Hi all!



I am a noob at all of this so be gentle, but feel free to tell me anything you see that doesn't make sense or you'd like to know why I picked something. Last time I made a watercooling build was about the time fish tanks went out of style for water cooling. Yeah, that long ago. I didn't do a good job then, but hopefully this time around... And yes, I am actually making two identical builds, apart from coolant color. My wife wanted a new computer while I was at it.

Without further ado, here's the current plan for the build!

The general idea is to go black with plexi / nickel blocks apart from coolant which is undecided atm. We'll see how it goes in practice but that's the general thought.

General non-cooling parts
Case: Phanteks Enthoo Primo - Big, honking Full Tower with loads of room and prepared for water cooling.
PSU: EVGA SuperNova G2 1600W - Should be plenty of power for what I'm putting in it.
Motherboard ASUS x299-Deluxe - Nice 10 PWM board with loads of goodies.
CPU: Intel i9-7900x - 10 cores. Overkill? Yes. But I can always... Nah, I won't lie. I just wanted it.
Memory: 64GB (4x16GB) Corsair Vengeance LPX 3000MHz CL15 DDR4. - Do I NEED 64GB today? Does anyone? Video editing 4k ? Maybe (I don't do that). I am a software engineer but 10 cores and 64GB of memory is overkill, even for me unless I run VMs. Loads of VMs. At the same time. Yeah, overkill.
Graphics cards: 2x MSI GeForce 1080 Ti EK X in SLI - I'm sure I absolutely need it to pull out that extra FPS.. Yeah, I'll keep telling myself that.
Storage: Samsung 960 EVO 1TB - Apart from the whole "it's awfully expensive", it's probably the sanest choice in this build. I can always add some rotating disk or an SSD for storage if I need it.
Monitor: ASUS PG348Q 34" 21:9 Ultrawide gaming monitor - Absolute joy to use for software development. It's the only thing I bought that I can actually use yet.

Cooling bits and bobs:
CPU Block: EKWB EK-Supremacy EVO X99 - nickel - Nickel base with plexi top. Hope to replace it with EK's Monoblock for the x299-Deluxe when it comes.
GPU Blocks: The one that comes on the graphics cards. Nickel base/plexi top/black backside - Fits the general build and I don't have to void warranty to install it. Easy choice.
Pump/Reservoir combo: Alphacool Repack - Dual Laing D5 Station incl. 2x Alphacool VPP655 pumps - After going through loads of ideas I ended up with this since I really wanted two pumps and it was the only one I found and as I was ordering from Alphacool anyway it was an easy choice.
Radiator (Top): Alphacool NexXxoS UT60 Full Copper 480mm 60mm thick radiator in push/pull pushing air out of the case - I think it should fit there as it's in front of the motherboard even if it hangs that low. Might be a pain to get cables in but I'll get it to work.
Radiator (Bottom]: Alphacool NexXxoS Monsta 480mm 86mm thick radiator in push/pull pushing air out of the case. - It fits. I wanted it. Yeah.
Fans (Radiator): 16x (8x Top, 8x Bottom) Noiseblocker NB-Multiframe M12-P PWM 120x120x25mm - Should be pretty good for what I want.
Fan (Rear): One of the 140mm fans that came with the case pulling air into the case - Good a place as any to put a case fan to blow air into the case. Possibly change the fan to something else down the line.
Fan(s) (Front): One or two of the 140mm fans that came with the case pulling air into the case - I don't know if the lower one won't be just pushing air in to .. nowhere really so I may end up not mounting it, but we'll see when everything gets here.
Fans (Side): The last two 140mm fans that came with the case pulling air into the case - I think I can place the computer in such a way that this is all doable this way.
Fan splitters: 2x or 3x Phobya 1-to-8 powered PWM splitters - The motherboard has 12 (!) PWM capable fan connectors (can be configured for either constant voltage, PWM or voltage regulation individually. I intend to drive 1 of the outputs to a Phobya splitter and drive the top fans with it, then the same for the bottom and use the PUMP and AIO connectors to drive the two pumps and the rest of the fans from the motherboard OR possibly drive the other fans from a splitter. All depends on cable lengths, etc.
Tubing: Alphacool Eisrohr 13/10mm PETG - Even though I've never done it I thought I'd give hard tubing a go and most places I read says to use PETG tubing, so I am.
Fittings (Hard): Alphacool Eiszapfen 13mm compression fittings - black - Should be pretty and safe enough.
Fittings Bent (Hard): Alphacool Eiszapfen 13mm compression fitting 45 degrees rotatable - black - Look at next item for description where this goes.
Y-Splitter: Alphacool Eiszapfen Y-connector 45 degrees rotatable - black - The pumps have two outlets, one will have a straight line going into the Y and the other one will have the above 45 degree fitting feeding it into the Y.
Temperature sensor: Alphacool Eiszapfen temp sensor G1/4 - chrome (black was unavailable) -I wish it was black but it'll connected to the Y-splitter above and it'll be behind the side panel so it hopefully won't be too visible.
Flow sensor: Alphacool flow indicator G1/4 with RPM signal - plexi - Undecided where I will put this, but it'll be.. somewhere. And it will be connected to the motherboard for RPM signaling.

Drain system:
The lower radiator will sit a little raised due to the pulling fans and the radiator inlet/outlet ports will be to the front of the case leaving the drain port on the radiator facing back in the case. I plan on making a hole in the case mesh right there and first putting an extender (if needed), a 90 degree bend, a ball valve and a plug. This means that when I go to drain the system I can just remove the plug, insert a soft tube with compression fitting, crack open the ball valve and draining should be easy. When done I'll just close the ball valve, replace the plug and voilá - drained system. Depending on how far from the edge of the case the radiator actually sits I might turn around the extender/l-connector/extender completely to have it closer to the case.
Tubing (Soft): Alphacool AlphaTube HF 13/10 (3/8" ID) - clear - Just your normal soft tubing.
Fittings (Soft): Alphacool Eiszapfen 13/10mm compression fitting - deep black - No reason why they can't be pretty at the same time, eh?
Extender: Alphacool Eiszapfen extension G1/4 outer thread to G1/4 inner thread - deep black - Connected in the drain plug in the lower radiator to get the connector out of the case in the back. This may not be needed.
L-Connector: Alphacool Eiszapfen L-connector rotatable G1/4 outer thread to G1/4 inner thread - deep black - Just a 90 degrees rotatable connector so the ball valve doesn't stick straight out through the back of the case.
Extender: Alphacool Eiszapfen double nippel rotatable G1/4 outer thread to G1/4 outer thread - deep black - To connect the L-connector to the ball valve and making it easy to have the valve pointing the way I want it to (up most likely).
Ball valve: Alphacool Eiszapfen 2-way ball valve G1/4 - deep black - Nice ball valve connected to the adapter.
Plug: Alphacool HF screw-in seal plug G1/4 - deep black - Just in case the ball valve doesn't hold pressure, this will seal the deal.

Coolant and Dyes:
Coolant Alphacool CKC Cape Kelvin Catcher - Seems good from what I've read.
Dyes Mayhems Standard dyes - I have picked a few colors and will decide on what I do when it's time to fill the system. It's highly likely our systems won't be the same colors.

So how do I run my loop?

The Dual Pump/Reservoir combo unit is obviously sitting in a 5.25" slot at a good height.
One of the outlets from the pumps goes via fitting, tube, fitting into the Y.
The other outlet goes through a 45 degree fitting, through a tube, a fitting and into the same Y.
The other end of the Y is connected to the temperature sensor, which neatly is inner thread-inner thread. Saves me getting an adapter. The adapter goes to a fitting and through a tube into the CPU block inlet.
The outlet of the CPU block goes to the top radiator inlet.
The top radiator outlet goes down into the top graphics cards I have not decided if I will go parallel or serial between the graphics cards.
Instead of using a terminal I will simply be using fittings and tube to connect them, so either two tubes between the graphics cards or one tube (and plug whatever holes need plugging). The outlet of the second graphics card will go to the front of the case to the inlet of the bottom radiator.
The bottom radiator outlet will go back up to the inlet of the pump/reservoir combo unit, completing the circuit.
Somewhere in a Good Position(TM) I will place the flow sensor as well, either visible (maybe close to the graphics cards) or hidden (maybe near the pump/reservoir combo or by the bottom radiator).

I can already hear "pics or it didn't happen!" - Well it hasn't happened .. yet.

Pics will however come! Both when I have all parts and some during the build which will hopefully start this weekend but if not then early next week. All depends on when the Alphacool stuff comes.

I have received everything EXCEPT:

Anything from Alphacool - don't know why it's taking time, payment was flagged as accepted monday morning but it hasn't shipped yet according to their site. Well, now I know and it should be shipped today or tomorrow. Apparently 3 minutes before me someone ordered the CPU block so they were out when I finally ordered... I have removed it from the order and they will ship it without it.
EK CPU blocks - Being shipped to a local store and ready for pickup Thursday or Friday this week.
PSUs - ETA is next week unless I find them somewhere else but anything high powered is basically sold out everywhere.

Some changes happened. The CPU blocks from Alphacool were out so I removed them from the order and the CPU blocks I will be going with are now the EK-Supremacy EVO x99 from EKWB. They are currently being shipped to a local store.

Alphacool just mailed me that the package is ready for shipping and will hopefully arrive early next week.

That leaves the PSU. It .. is .. a .. headache. Basically sold out everywhere I look.

If anyone knows where to get hold of something like an EVGA G2/P2/T2 or Corsair HX(i)/AX(i) at 1300W or more, let me know. Or something else with quality.

// Stefan

Update:

Loads of components are here already.

Alphacool delivery scheduled for this coming Monday (the 10th). PSUs are hopefully here Wednesday-Friday this week. We'll see.

Build will actually commence today with some easy stuff like putting in the NVMe SSDs, CPUs, CPU Blocks, Memory and screwing it into the case. Yes, the risk is that I have to remove it from the case again but at least they're not in the way.

Also will start removing superfluous stuff from the cases like unused cables, 3.5" cages, etc.

// Stefan

Ok, so there's been progress.

Both motherboards are in, with CPUs, CPU blocks, memory, SSDs in the correct place, all inside the case.

Machine #1 has gotten a lot further (basically we're finishing up this one and then switching to the other one).

It has a temporary EVGA G2 850W PSU inside of it as I am .. still.. waiting.. for .. the.. PSUs.. A company said that they can get hold of 6 with no issues and I should have them this Wednesday or Thursday. I called them today and guess what? They haven't received them and they don't know when they will.

On a scale from unprofessional to professional they go really, really low. They have my money, which of course they can give back if I so wish, but they don't actually have any PSUs or a way to get hold of them. I will not name and shame them. If they would've at least called me / mailed me telling me that "oops, seems we CAN'T get hold of them!" then at least I would've known.

Ok, rant over.. for now.

Side view of almost everything installed except graphics cards and water cooling parts.


Front view.


Side view of other side. Yeah, loads of cables but what else can I do with them?


Rear view. That's how I ended up doing the drain, it's connected to the bottom of the radiator so draining shouldn't be an issue.


Last we did before sleep was to get the dual pumps/reservoir installed, but I haven't snapped a picture. I'll fix that later.

After sleeping we installed the graphics cards with the tubing between them. I'm going parallel for the looks.


More updates to follow.

// Stefan

Also,

the reason why there is a piece of paper sticking out from the fitting going to the pumps is because we did a few tests.

Since I don't have any other way of cooling the CPU we did a short loop with soft tubing where we connected one of the pumps (plugged the other and didn't give it power) to the CPU block and back to the pump/reservoir and checked if it POSTed (using an old Radeon 5870).

Good news : It works!
Bad news: It leaked. A little.

We thought we had checked all the fittings, etc to see that we had all the o-rings as we should and .. seemed to have missed one. We had a very tiny leak from the in-port to the reservoir. About 1 drop every 2 minutes. It was due to a missing o-ring. Now, we haven't tested to see if it leaks with the o-ring there but we're confident that was the only issue. No other leaks in the system.

I've done my first bend! First attempt without using a tool. Obviously a heat gun and a silicon insert but all done by hand and to me it looked good. It's the one that goes from the temp sensor after the Y-connector after the pumps to the CPU block.

Won't share a picture until more tubing is installed. We're currently working on bending the tube from the CPU to the upper radiator.

// Stefan
 
#6 ·
Some more progress made, but didn't spend too much time on it unfortunately.

Done bends:

Reservoir/Pumps (really temp sensor after Y-connector) > CPU block (1 bend).
CPU block > Upper radiator (2 bends).
Lower graphics card > Lower radiator (2 bends).

Left to do:
Upper radiator > Upper graphics card (4 bends probably).
Lower radiator > Reservoir/pumps (3 bends).

This is on system #1, the other one we haven't gotten as far on yet.

We're going to get started on it in a few hours and hope to be able to fill it with water this session.

Looking at the last picture up there makes me wonder if it may not be nicer to have the PCI-E cables coming in from the side... What do you guys think?

Thanx!

They are huge but to be honest, when you're holding the Monsta in your hands and looking into the case anything smaller would feel small. Even the 60 feels small if it'd go to bottom.

Since last we've had some things happen.

I thought one machine was done yesterday but then we noticed two boxes with flow sensors lying unopened. Argh!

Decided that if we have to empty it off fluids to install the temp sensor we may as well do some other changes as well...

One annoyance is that the CPU FAN and CPU OPT fan headers can only work according to the temperature of the CPU. I mean, it's not illogical but if I'm water cooling it I may want to base it on something other than the CPU temperature, like say .. the water temperature. We had the upper radiator fans connected to CPU FAN and lower radiator fans connected to CPU OPT.

The tubing near the graphics cards was a major source of turbulence and I had a feeling that was giving me worse performance.

So off we went draining the system (second time..) and did the following:

Install the temp sensor vertically just before the inlet into the reservoir. Pictures in a little bit.

Switch from Parallel to Serial arrangement of graphics cards.

Move fans to different motherboard connectors.
Current mapping is:
CPU FAN - Pump 1 - We can get the rpms but the pumps don't support controlling by default. Alphacool 655T.
CPU OPT - Pump 2 - Same as above.
CHA 1 (Chassis 1) - Phobya PWM splitter connected to upper radiator's fans (pushes air out of the case).
CHA 2 (Chassis 2) - Phobya PWM splitter connected to lower radiator's fans (pushes air out of the case).
W PUMP+ (Water Pump) - The top front mounted 140mm Phanteks case fan (pulls air into the case).
AIO (All In One) - The rear 140mm Phanteks case fan (pulls air into the case).
M2 Fan - Flow meter with RPM signaling.
EXT1 (External 1 on ASUS Fan board) - The bottom front mounted 140mm Phanteks case fan (pulls air into the case).
EXT2 (External 2 on ASUS Fan board) - The top side mounted 140mm Phanteks case fan (pulls air into the case).
EXT3 (External 3 on ASUS Fan board) - The bottom side mounted 140mm Phanteks case fan (pulls air into the case).

I had the machine on over the night doing stress testing of the GPUs. Only a mild overclock at ~1950MHz on both cards. Temps on the graphics cards were 59 and 66 degrees respectively.

Now I've had it stress testing the same for about an hour and temperatures have stabilized at 56 and 59 degrees respectively - so I was right! Serial is better for me.

I can also report that with my setup I have ~320 liters per hour which equals 1.4 GPM (Gallons per minute).

I don't want to leave the machine running with CPU @ 4GHz going full tilt as well as the graphics cards as the draw at the wall is then ~880W and I have a EVGA G2 850W PSU in it right now (since I'm still waiting for the 1600W ones...). Now, I know that the 850W isn't at the wall but actual delivered and the efficiency isn't 100%, so I should be safe but I'd rather not push it.

I will however do some tests to figure out the temps with everything going full on.

All temperatures reported are with the same not quite aggressive fan speeds.

So!

Pictures!

Here are pictures from before and after the last changes. Enjoy.

Before the changes:

Side view with tubing.


Parallel cooling of graphics cards. Loads of turbulence here.


CPU block.


Side view showing rear fan.


Front view. The big cover in front of the front fans is removed on purpose for air flow.


Side view (other side).


Rear view.


Drain solution.


I stuck the Thunderbolt 3 card in between the graphics cards.


After the changes:

Side view with tubing and flow meter.


Flow meter installed.


Graphics cards now running in serial instead of parallel.


CPU block.


Lower tubing.


I plan on adding more pictures later of when it's running, etc. I also plan on getting some LED strips since it really is dark in there and the fluid is not showing off at all, especially the front.

The flow meter was an interesting problem. After figuring out where to stick it we cut the tube and mounted everything and started filling the system. When we turned the pumps on the flow sensor was rotating as it should but then at some point it stopped. I don't know when or why - it just did. Some googling led to a thread somewhere that pertained to a different flow sensor and that particular one can't be mounted vertically. I spent over an hour trying to find any wording on the box, on the page, threads, etc if the Alphacool flow meter can or can't be mounted vertically and there simply is no word on it at all.

So we started planning on where can can move it, how we can test if it works or doesn't in vertical until it just ... started up. Just like that, after quite a long time and it's running fine. Now, I am really happy as I was not looking forward to using a whole pipe to replace the one we cut.

Anyone know anything about this issue? Can you mount the Alphacool flow meter vertically or not? I mean it works now - yes, but I want to know any other word.

If I don't hear anything I'll contact Alphacool and ask them myself.

Any other info or pictures you all want?

Oh and yes - the thing is really, really heavy. It was no fun moving it.

Very nice rig Stefan. Your build was very helpful to me as i am/was working on my upgrade today. I upgraded from a corsair 760t full tower case with 2 evga 970ti in sli to moving everything into the same case you have. And also my first attempt at putting in a 16od 12id petg custom loop. I spent about 6hrs today started the transfer. I also have the same bottom rad as you except its the monsta 360 as i put in a alphacool 240x46mm rad in the front and same rad as you on top except its a 480x30mm. I went with everything else ekwb. I have quite a few questions for you if you dont mind answering them to help me out a bit as we have very similar builds.
Again i would like to say you have a great rig and looking forward in exchanging tips. 1 fellow phantek enthoo primo owner to another.
I am off to sleep for the night.

What kind of SLI scaling are you getting with this rig? I am just wondering because with my X299/7900X setup it worked much worse than only single card. However I went back to X99 and all works great again with 2x1080TIs.

If I'm able to help out somehow I'm really happy!

Bring it on!

I haven't tried any gaming tests yet at all.

I am planning on running some tests soon but I'll let you know.

What board do you run it on?

Nice job. I think my fully w/c and filled Primo weighs something like 78 lbs... so I know your (back) pain
biggrin.gif


If your PWM control doesn't work out you may be able to pull PWM signal from the GPU like I did, but it could be a lot of hassle to change over to that.

Also I don't think that plastic plate in the front blocks so much airflow, but a really huge bottleneck for these cases and big radiators on the bottom is the bottom. Since the case basically has a shroud all the way around the bottom except for about 2-3mm "feet" and only the back is open, it has pull almost all of the air through that small gap in the back.

If you have any issues or concerns and turning your fans up isn't working, I suggest putting some blocks of wood or something under the feet and lift it up 1" or so and then retest, to see if your bottom fans/radiator are being starved of fresh air.

#18 ·
Thanx!

And yes, I haven't weighed it but I have had to carry it 3 times so far with water
smile.gif
It's heavy!

PWM control: It's working perfectly fine now that I redid the connections. I did consider going with the PWM from graphics card route but decided against it. This way I can control it just fine.

Front plate: Really? Interesting, maybe I'll mount it again as it looks nicer with it.

Bottom: We have discussed raising it and haven't done it (yet). We just may do it though. A difference is that I'm not pulling air in through the bottom, I push air out:

Top and Bottom radiators: Fans push air out of the case. 16x 120mm 2000rpm fans through radiators, so restricted.

Rear, Front and side fans: Fans pull air into the case. 5x 140mm 1200rpm fans (I think 1200rpm) with no restriction.

But with a Delta T of 9 degrees, do you consider cooling inadequate when running graphics cards at 100% at 2.0GHz?

#19 ·
The front intake may be more important in your build with that airflow setup.. I suppose you can test with that panel on/off.

That's a great Delta T, so likely you won't have to change anything. You haven't tested with CPU OC and running 100% though have you?

Well I have but with a lower GPU OC due to getting to close to the limit of what the PSU can deliver. I was seeing 880-890W at the wall and I have an EVGA G2 850W PSU in the system while I wait for the 1600W to arrive.

I stressed everything for about an hour and it ran fine. Lower GPU clock and 4.0GHz, everything stressed at once. I can't remember the numbers now but they were not much different. Obviously the CPU temp was higher but I think I saw 53 C or so on the CPU.

Hi Stefan

Looks good there but...

I would expect bit better temperatures on GPUs with such rad space like you have, in my case I'm running EK XE360 360mm on top with 6*Phanteks PH-F120MP and on bottom Mayhems Havoc 240nm 60mm thick radiator with EK Vardar F3 1850RPM, delta during gaming right now is around 5-7°C but usually in colder weather my water delta is around 2-5°C

My GPUs temps are on top GTX1080Ti are in region 36-38°C with 2138MHz OC,middle GTX1080 with 2164MHz OC with temps in region 34-36°C and bottom GTX1080 with 2100MHz OC in region 34-36°C these temps are during the rendering and in gaming usually only Ti I use and temps are there in region 36-38°C as max

If budget allows then get Aquacomputer Aquaero and MPS flow sensor, Aquacomputer SPLITTY9 depending on amount of fans, if you are running same fans then add at least 2-3 and you should be good, through the Aquaero you can control any fans so easy and control fans based on water delta

Here is how it looks, at these pictures I'm still running at top Noiseblocker BlackSilent Fan XLP and tubing Mayhems UV White 13/10,right now I'm running EK ZMT 16/10mm and fluid for time being EK CryoFuel Blood Red





Hope this helps

Thanks, Jura

Hey. Jura.

Thanx a lot. Food for thought. I mean just looking at our two machines I should be killing you on cooling and the opposite is happening.

Two things I can definitely think are happening in my case:

1) Bottom constrictive.
2) Case fans are 140mm 1200rpm fans - maybe they don't simply push enough air into the case?

I looked into getting a fan controller earlier on but decided against it. I read about people having problems controlling various things and ended up with just saying "no, my motherboard has a total of 11 PWM outputs, I'll make do with setting up the BIOS or using something like SpeedFan to control everything."

And frankly, regardless of what I'd use, the temps still be the same, the controller might control RPMs of fans better, so they stay quiet when not needed more often and spin up faster when needed, but that's about it. My fan profiles are already fairly agressive.

I don't use Delta T for, but absolute temp for measurement.

<=30 C - Radiator fans 50%, case fans 70%.
30 C - 40 C - Radiator fans 75%, case fans 90%.
>=40 C - Radiator fans 100%, case fans 100%.

All fans are set to the water temp meter for input and it's holding steady at between 44 and 45 C on full GPU load.

Please come with more ideas and feel free to tell me some of my conclusions are wrong.

// Stefan

I have about 4 inches from the end of the bottom monsta 360x86mm to the front rad 240x46mm so hoping that will allow better airflow coming in from the front and side. I have the same intent as you Stefan push/pull top and bottom both pushing air out of case and 1 140 fan in the back and 2 120's in the front pushing air into the case. One problem I came across was my lack of forsight and thinking ekwb configurator knew what it was talking about when I purchased everything. unfortunately I didn't get a 5 1/4 bay res, instead I got stand alone cylinder for res and pump will go in the back next to the psu. problem is my evga 1080ti ftw3's are monsters. had to take out both brackets and I see you still have I left installed. mine are to long and due to the size of the res there basically was no where to mount it.
the only thing I could come up with was to drill holes and mount it horizontally just above the bottom rad and just below the 2nd gpu. I have two of them in sli. my concern is air bubbles. I picked up a small res from amazon that works in a horizontal position that I can set at the bottom of the 5 1/4 drive bays. will post some pics to show ya what I mean. if it doesn't work I will have to go with a res like yours.
my son and I finished installing the gpu and cpu water blocks. never did that before lol. learning something new every time I upgrade this thing. Do appreciate your input and most def will need some help with fan and sensor installs.

I read about people having problems controlling various things and ended up with just saying "no, my motherboard has a total of 11 PWM outputs, I'll make do with setting up the BIOS or using something like SpeedFan to control everything."

And frankly, regardless of what I'd use, the temps still be the same, the controller might control RPMs of fans better, so they stay quiet when not needed more often and spin up faster when needed, but that's about it. My fan profiles are already fairly agressive.

I don't use Delta T for, but absolute temp for measurement.

<=30 C - Radiator fans 50%, case fans 70%.
30 C - 40 C - Radiator fans 75%, case fans 90%.
>=40 C - Radiator fans 100%, case fans 100%.

All fans are set to the water temp meter for input and it's holding steady at between 44 and 45 C on full GPU load.

Please come with more ideas and feel free to tell me some of my conclusions are wrong.

Hi Stefan

Bottom of Enthoo Primo is restrictive with filters installed,I'm running or using them too and this shouldn't cause high temperatures

Regarding the case fans,running them as well and they're pretty good and although they're not PWM fans but still with supplied Phanteks hub they can be controlled through the BIOS easily

If you are looking get better fans for front etc then have look on PH-F140MP or EK Vardar, BeQuiet Silent Wings 3 etc but I'm happy with them

Regarding the running the fans through the BIOS, been there and after switching to Aquaero and Aquasuite I'm not looking back at all

Absolute temp is good but still I would rather control my fans based on water or air delta which makes more sense for water cooling setups

44-45°C water temperature is bit high, in very hot weather conditions or high ambient temperatures 28-32°C my water temperature is around 1-1.5°C higher than ambient and under load usually is higher by 5-7°C depending on fan speed which I usually change more than often

Other thing with which I'm maybe wrong is orientation of yours CPU block, assume OUT on CPU block going to reservoir IN?

Hope this helps

Thanks, Jura

Forgot to add in my case bottom fans are set as intake, top fans as exhaust and exhaust fan is exhaust and case fans are set as intake

@FIDDY57

Thanks there

Regarding the fans all depends on fans used and how you want to control them,if you want go route of the standalone fan controller then Aquaero 5LT or 6LT are cheaper options than display version of the Aquaero

If you want go route of the BIOS this depends on motherboard and if motherboard have T sensor or can read T sensor, then you can control the fans based on water temperature which I would do,some motherboards do have these T sensors like Asus

Hope this helps

Thanks, Jura
