New to WC: Advice for i7-2600K and 2xGTx580 loop(s)

post #1 of 6
Thread Starter 
Hi,

After plenty of reading - I've decided to spend some of my long saved bonus on WC'ing and upgrading my PC. This will be my first time watercooling - i've thought about doing it the last 2 PC builds I have done, but have finally decided to jump now. I'm OK with building PC's, sleeving, re-wiring fans/molex looms etc so not a complete modding noob - I just need some confirmation/advice on the loops and config from people with more knowledge and experience than I...

Current setup (all air cooled):
Antec 1200
ASUS Maximus IV Extreme-Z
Intel i7-2600K
MSI twin Frozr GTX580
16GB G.Skill Ripjaws 1600
ASUS Xonar DX soundcard
OCZ Vertex 3 240GB SSD
+ some other HDD, Blu-ray etc

What I am thinking of getting/upgrading:
PC Upgrades:
Case-labs case (exactly which one depends on the rads needed and ofc some future upgrade proofing)
Corsair AX1200 PSU
2nd GTX580 for dual SLI setup

Watercooling stuff:
CPU Block - EK Supreme HF Acetal
MB Block - EK-FB ASUS Max4 Extreme - Acetal +EN (Nickel)
2 x GFX Block - EK-FC580 GTX+ - Acetal +EN (Nickel)
21 x Res(s) - EK Multioption X2 advanced 250
2 x Pump(s) - MCP655 vario
2 x Radiator(s) - XSPC RX480 or 360 (depending on needs)
Fans - Scythe GT AP15 fans for rads (most likely just push) (+ a few for case/HDD cage)
1/2" ID 3/4" OD Masterkleer Red tubing Primochill Primoflex Pro - Distilled water + coil
Bitspower comp fittings
Aquaero XT 5 Controller + Poweradjust
1x Aquaero copper block

So onto the specific questions
1) Should I go for one or dual loops?
For dual loop I was thinking - Loop1: CPU+MB+Aquaeroblock, Loop2: 2xGTX580

2) Are 2 x 360 Rads enough for all these?
Would 360's as opposed to 480's give me problems for possible future upgrades? I dont want to be forced to use a bigger case next time I upgrade. I'd prefer to keep the AP15's low speed so its quiet if posisble.

3) Is it worth cooling the MB?
Is it worth cooling the aquaero? I hear they can get pretty toasty

4) Should I parallel or series the GPU's?

If you want to block the mobo and you get the caselabs then yes do CPU/Mobo and GPUs loops

You're getting two rads so you might as well. And yes 2 RX360s in push pull with low RPM GTs would be fine.

If you can afford to do both then you might as well. Mobos do get hot but they are made to stand the heat.

You're only going to see about 1C difference in series.

BTW, If you wanted to do a single loop then you could just about fit it all in the antec.(GPU 360 rad on the back would have to go outside.), well you could do the dual loop, too even.

Change that to Primochill, its the best tube around IMO.

Thanks for the response,

I think I will stay away from the EK nickel blocks until its clear what is going on with the reports of plating/corrosion problems even on EN versions. The copper+Acetal stuff from EK doesnt look too bad anyways and is a little bit cheaper too.

I had a look at primochill tubing on a few sites, looks good. I might get a metre of two of it and the masterkleer and see how I like both for look, and bend etc. I did read some advice saying to buy cheaper tubing (like masterkleer) for first builds as changing the loops a lot is quite likely on your first time watercooling.

I'm still uncertain of single vs dual loop and if I should go for M8 case + 2 x RX360 or MH10 + 2 x RX480 rads.

You can run everything in a single loop if you desired to, but running dual loop give you more flexibility on maintenance on the loop setup if you want to change out certain parts.

2 X RX360 is enough to cool the entire setup even if you expand in the future. Unless you want more room in the case, RX480 won't be necessary.

I am begining to think the following might be the best approach - since this will be my first watercooling project

I will go for a caselabs M8 rather than MH10
It saves approx £150 of the total cost of the project through both a cheaper case & shipping and cheaper rads. The 2x 360 rads should be enough for now and the M8 has enough room for the two I am planning in the roof and more if needed later (sides, bottom, even a ped)

I will also go single loop and remove the MB block and aquaero block
The loop will be
OPTION1: Res >> Pump(s) >> Rad >> Rad >> CPU >> GPU >> GPU >> Res
OPTION2: Res >> Pump(s) >> Rad >> CPU >> Rad >> GPU >> GPU >> Res

Single loop should look cleaner, and be easier to start with. If I fancy Dual loop system later I can buy and extra res and new tube/fittings.

With regard to single loops - is it best to use 2 pumps for a loop of this size? and should I go with my originally planned MCP655 or 2x355?
post #6 of 6
2 pumps kind give you a backup measure in case 1 of the pump fails, with your loop I don't see having 2 pumps helps, 2X355 is too much head pressure for that loop.

A single mcp655/355 pump will run that loop without much problem. Just to point out more pump = more heat dump into your loop, however if you going with 2X360 the effect is minimal. Personally I prefer the MCP655 over the MCP355 due to lower noise level and speed variable option.
