Water cooling in 650d?

Hi guys, I want to build a watercooled computer using the 650D with 2x gtx 580 or 2x gtx 590,

To be honest, I don't think it's possible for the gtx590 water cooled in the 650d cause there isn't much room for big radiators...

but i really want to keep the tower a midsize tower, is it possible to cool 2 gtx 580s + CPU

with maybe 280mm radiator up top with 2 140mm exhaust fans.

with maybe a 200mm radiator behind the intake fan.

with maybe a 120mm radiator at the rear exhaust fan.

I want to know if I can stuff enough water cooling in the 650d to adequately cool off 2x gtx580/gtx590 and CPU.

Also... will making the CPU and GPUs have a separate loop help cooling performance?

Here's the link to my build http://www.tomshardware.com/forum/323296-31-650d-water-...

With a custom loop I don't see why not. Here is an example of a cutom loop in a 650d using 2 GTX 480's. the GTX 480 is roughly the same size as a GTX 580 at 10.5" and the GTX 590 is only a half inch longer at 11".





Here is the build log, maybe it will help.

OH MY GOD THANK YOU FOR FINDING THIS. :ouch: 

But my question is will the config he has, Slim Dual 120mm Radiator XSPC RS240 and Phobya 200mm Radiator cool i5 2500k OC and 2 gtx 580s at OC as well.

If mounting a radiator off of the back of the case wouldn't bother you, I would recommend doing that as well... you would definitely be able to overclock with a 200mm rad, a 2x120mm, and a 3x120mm hanging off of the back of the case with something like this...

That would be my suggestion because you would need some serious fans in push pull if you planned on cooling all of that with a RS240 and 200mm Phobya, and an overclock would probably be out of the question.

What if I just want to water cool the 2 gpus, and use a h50 or something basic for the CPU, will the 200mm rad at the intake and another 2x 140mm uptop cool the gtx 580s? Or maybe 2 200mm rads to cool 2 gtx 580s?

You could do that but your i5 2500k is going to need some love with an LCS...it isn't going to perform much better than your current 212 in push/pull.

The GTX480 TDP is 250 watt, where a GTX580 FTW Hydrocpper is 263 watt.

This guy used a single 200mm radiator in the intake and cooled both GTX 480s, why can't I use a 280mm exhaust up top to cool 2x gtx 580s? I don't need chilly 40C temperatures, as long as they'are lower than 55C I am happy.

that leaves the 200mm radiator to cool the i5 2500k, which is sufficient since sandy bridges don't even run hot, even at 4.5ghz mine doesn't even hit 60C.

Another thing is.. can I have a single loop with 2 radiators?

I was thinking

Res > Radiator > GPU 1 > GPU2 > Radiator > CPU > Res (This may be difficult to achieve)

or

Res > Radiator > CPU > GPU 1 > GPU 2 > Radiator > Res

(Not sure if water cooling CPU plus 2 GPUs are going to be okay without going through radiator between them.)

Yes, most people here run a single loop with 2+ radiators...including me.

Loop order doesn't matter; temps really won't be much different than maybe 1-3C at different points in the loop (actual water temp, not temp reporting software readings).

You can cool with those components if you want; do you happen to know the heat watts dissipated by each of those rads at the fan speeds you want? I'm thinking you are still looking at a poor delta, but it doesn't appear that is a priority. (Update: See below)


1,764,000/1,784,320= Phobya is ~98.8% total volume of the MCR320, with similar FPI and thickness. I'd assume it would perform similarly, percentage-wise? (We haven't seen too many benchmarks of this rad vs. most other 120mm/140mm rads.)

I guess my real question is this: most GPUs run in the mid 60's Celsius with the stock air cooling...so why is the magical number of '55C' that important? You are going to drop this much cash on a water loop for temps that might be possible using an aftermarket air cooler for these cards and some good case fans. I understand this is your build and you have an idea of what you want, but given the hardware you are wanting to cool, you are selling yourself way short on the potential for your loop. Just my opinion...trying to help and list alternatives. I just don't understand people that are dead set on water cooling and also dead set on 'only using X-amount of radiators' in the loop'. Usually, one or the other has to give somewhere...unless performance is less important than saying 'I have a water cooling loop' in your case.

Edit: I did some quick math and compared the Phobya 200mm vs. the MCR320; interesting results.

Phobya 200mm = 245x200x36mm (1,764,000 mm^3 total volume)

MCR320 = 410x128x34mm (1,784,320 mm^3 total volume) ~500 watts, 2000rpm fans


That being said, I think you could do well with a 200mm and a 2x140 (you mentioned a 280 in the initial post...meaning a 2x140?) I'd make sure you have fans in the 1800 rpm range and 65+ CFM.

Rubix, you're awesome :) 

I am very new to all this water cooling stuff so yea, I'm so glad you're around to help me out.

Alright, saying that the Phobya 200mm + 2x 140mm is enough to cool two GTX 580s and the CPU, is the delta temp going to be okay? or is it really not worth the water cooling?

The reason I want to go water cooling is cause I love computers, and I built my first one not too long ago and I'm itching to build another one with water cooled components.

Also because I want a smaller case that doesn't sacrifice power, and one that's not as loud as my HAF X because the fans on my GTX 560 Ti's sound like jets.

Keep in mind, my plan is to get 1 gtx 580 hydrocopper2 and add another one later down the road.


-----------------------------------------------------------------------------------------------------------------------------------------------------

So I'm thinking Phobya 200mm at the front of the case with intake (push/pull) config using the two 200mm stock fans that come with the CM 650d case, unless you think those stock fans are too crappy for the radiator.

And buying two 140mm fans 1800rpm range and at 65+ CFM? What about high static pressure? is that important?

Which fans should I look at? How about these?

As for the 2x 140mm radiator, which one to get?

Here's an article I read to pick out these two, they seem to perform similarly unless I'm missing something.

Black Ice SR1 280 ($115)

or

MagiCool Slim dual 280 MC ($60)

http://www.frozencpu.com/products/12705/ex-rad-230/Magi...

suggestions welcomed.

EDIT: What if I added a small 120mm radiator at the rear exhaust like this into the loop? making that 3 radiators for the entire
loop would this ensure I can cool GPUs + CPU?
