New To WC, Advice Requested

post #1 of 16
Thread Starter 
First off hi!
I've been lurking the forums for years and have been building computers for a long time. After getting my new setup going for about a year I've decided to go WC for the first time.

I have a 800D case, i7/920/3.6Ghz, 2x XFX HD6950 (bios modded), Gigabyte X58-UD3R, Corsair HX750 using a H50 for the cpu and stock on the video cards. I primarily use this system for gaming and just recently purchased the vid cards which are fairly noisy and get really hot. I had to underclock my vid cards to get it from over heating. My primary goals for this build being (priority in the order listed):

Noise
Reliability
Temperature

I want to cool primarily my video cards as those are where most the issues are coming from but I figure I'd cool the cpu while I'm at it. My aim is not to have the coolest system out there but to reduce noise (my vid cards are like jet engines right now), get temps down (45C> cpu, 65>gpu loaded) I'd like any suggestions have to offer. Below is what I've come up with by reading around, let me know what you think.

Loop:

Res > Pump > 360 Rad > CPU > 120 Rad > 2 GPUs > Res

Parts:

Pump: Swiftech MCP35X = $90
Res:Swiftech Reservoir for MCP35X pump ~$20
360 Rad: looking around ~60
Single Rad: Feser X-Changer 120 = $30
VGA Block:2x EK FC6970 Nickel + Acetal ~$210
CPU Bloc: EK Supreme HF Nickel + Acetal Rev2 ~ $80
Tubing: Tygon R-3603 Tubing - 7/16in. ID X 5/8in. OD x10ft ($3.50x10)=$35
Fans: 4x Gentle Typhoon AP-15 = $62
Fittings: XSPC G1/4" Barb, 1/2" ID (4x) = $8
Antimicrobial: silver kill coil = $4
Liquid: Distilled water
Drain Port: Danger Dan threaded T + Plug = $6
TIM: Shin Etsu X23-7783D for GPU, Indigo Xtreme for cpu = $38
Hose Clamps: Using 7/16" tube with 1/2" barbs, so probably won't need it
Misc: Teflon Tape = $1

Shipping:$12
Total: $626

I'm hoping to keep pricing below $600, so I'll probably have to get some of those parts used or if anyone has suggestions for alternates with similar performance. If possible I'd like to mount thing internally but it's not a requirement so any suggestions in this department would be appreciated.

Thanks!

Why not get a rasa 360 and 2 ek blocks for ur gpu. Would save u allot of money andwoyld be just as good as ur custom set up. Main advantage wosuld u be getting rid of ur unesessary expenses ie tubing etc. Plus u can easily upgrade this system for future addons

I would put a 360 rad in the top and a 240 rad in the bottom, wait that's exactly what I did in my 800D case and the temps are good. I started out with this kit,
http://www.crazypc.com/products/h2o-220-xt-9378.html
and built it up from there. I did replace the tubing with tygon and have since replaced the barb fitting with bp compression fittings.

do you want to save 150.00-200.00 or make it look really nice

best for price.
get a rasa 240mm rad kit it will do the cpu and if you want you could add motherboard blocks to that loop as well (110.00) www.sidewindercomputers.com

ek water blocks for the gpus (I have the ek's they are great)
swiftech mcr420-qp rad (480mm) or you can get by with a mcr320-qp (360mm)

the rasa kit pumps 750l/ph so you should be fine

if you want a little better use the rasa kit as loop 1

get a swiftech micro res and a 355 pump and build a second seperate loop for the gpus

the 800d will fit a 480 in the top with just a little work
the cosmos s case will also fit a 480 in the top with a little imagination as well

your next and best alternative is as follows

Item Options Unit Price Qty. In Stock Cost
Swiftech MCP355 / Laing DDC 12v DC High Performance Pump [remove]

$69.95 Yes $139.90
XSPC Rasa CPU Acetal water block [remove]

$48.95 Yes $48.95
XSPC Acrylic Dual 5.25in. Reservoir for Two Laing DDC's [remove]

$49.95 Yes $49.95
Swiftech MCR420-QP Quiet Power 4X120mm - Matte Black [remove]

* Choose your fittings : x2 Bitspower Shining Silver 1/2in. ID Barb (+4.00)

$73.95 Yes $73.95
Swiftech MCR220-QP Quiet Power 2X120mm - NEW Matte Black [remove]

* Choose your fittings : x2 Bitspower Shining Silver 1/2in. ID Barb (+4.00)

$44.95 Yes $44.95
Bitspower G 1/4in. Silver Shining Fitting for 1/2in. Tubing #BP-WTP-C01 [remove]

$2.25 Yes $13.50

Subtotal: $371.20
Total: $371.20

add your gpu cards for the best loop still around 600.00
all these parts where from www.sidewindercomputers.com

the above parts list would be your best loop for your cpu and gpus
it would be a dual loop 1 for cpu (and motherboard if you wanted later)
the 2nd loop for the gpus only

use the 240 for the cpu loop and the 480 for the gpus, you could squek by with a 360 instead of a 480 but the cost is neglegable for it

swiftech rads are rated best over all, dollar for dollar check skinnielabs

First off, welcome to the forum

I like what you have going there with your part choices, shows that you have done some research. I would not recommend the Rasa kit for your loop, mainly because the pump is a bit weak when it comes to pushing through 2 rads, a CPU block and two GPU blocks. If you can get the Rasa RX360 kit and replace the pump for less than getting the parts you need separately then it might be an idea.

The only thing that I did not like on your list were the NF-P12s. They do not perform well as radiator fans at all; check out Martin's testing for results.

I know you already have them, but if you want a low cost replacement, Yate Loon mediums are a good bet. For a noise / performance fan, look at the Scythe GTs, unbeatable performance but quite expensive.


Couple of cost saving options for you to think about;

Switch the EK Supreme for an XSPC Rasa block, a bit less performance but a lot less cost.

Look at getting a GPU only block, rather than a full cover. They are cheaper and you can use them on future cards, but you will need some method of cooling your vram / vreg.

Go for 7/16" barbs with the 3/8" ID tubing (or 1/2" barbs with 7/16" tubing). This removes the need for clamps as the tubing will need to be stretched over the barb, and forms a tight enough seal by itself. Slightly cheaper with a clean look.

Can a 240 mount on the bottom of the case without any modifications? I'd probably have to remove my HDD tray?

While having a dual loop system sounds tempting I think that might be more that I can chew on a new build. Plus I'd have to buy two pumps and rezs. But it looks like most people are suggesting XSPC rad's as a better $/performance.

Thanks, it was probably long over due

If figured I probably couldn't get away with it seeing as most people use the Gentle Typhoons. I'll definitely look to see if I can get some.

Sounds good but I don't know how else I'd cool the vram/vreg so I'll probably just end up paying the premium on the blocks. It's unfortunate that there doesn't seem to be as many options as the GTX480's but it is relatively newer.

Will the press fit of the tube be enough? I'd be afraid of my friends messing with my computer and accidentally pulling a hose off, though it may not be an issue if it can be tugged on lightly.

Anyway, Thanks for all the great information. Also what opinions does everyone have about the combined rez/pump/rad that I mentioned? Will that pump be enough for the system I spec'd out?

because the rasa kit isn't near as good as a custom loop...

If I were to go with a separated pump, rez, and rad any suggestions in that department? I'm thinking about this with the pump, rez, and quad rad mounted behind the case so I don't have to have two rads.

The price / performance king is still the Swiftech QP series, and they perform reasonably at all fan speeds. The XSPC RX and BlackIce SR1 series are good for low air flow, and the BlackIce GTX series are good for high air flow, but they tend to be a bit more expensive. If you haven't already read it, Skinnee's 360 rad roundup has some great information. The results for heat dissipation against fan speed at high performance level look like this:

You can get away with it. They will work but they wont perform well, even from a noise / CFM perspective. Comparing the results for the Yate Loon medium (blue line) against the NF-P12 and the Gentle Typhoon from Martin's test you get this:



Lower and to the right is better. As you can see, at full speed the NF-P12 is quite noisy, a resonance issue which happened on my sample too, and it also doesn't push much air. It will work, just not as well as a cheap Yate Loon (~$5 each) and nowhere near as well as a GT.

Yes, using a larger size barb than the tubing will be tight. You will need to heat the end of the tube to get it on, either with some hot water or a hair dryer, and it will not pull off easily. In fact to get the hose off the barb you will probably have to cut it off.

The pump in that system will be more than enough, the MCP35X is a beast. I can only assume that the radiator will perform the same as a normal MCR320QP as it is basically the same thing. The only thing I would be wary of is if the res/rad/pump combo fits in your case. I don't know how much extra space there is in the 800D at the end of the rad mounting, might be worth a measure.
