Need Advice on Coolign CPU & Tri SLI please

I have recently started a project in a TJ07.

Am intending to cool a QX9770 overclocked 4ghz and 3x TRI SLI GTX280's

I originaly decided to run 1x feser xchanger 480cm quad rad in the bottom EK 150cm Res and DDC 1T ULTRA Pump.

However am getting gremlins as to the GTX's heating my CPU up too much.

What do you guys think will it heat the CPU or will the difference be negligible? I would rather the one 480cm rad for neatness As I can't see a really nice place for anymore rads to go except modifying the roof:eek:, and mounting another pump will make it that much more complex.

Any thoughts???
 
For one of my projects I'm actually in quite a similar position.

I too was thinking of using a Feser 480 in the bottom of a TJ07, but also maybe trying to squeeze a dual rad at the end of the PSU. I haven't measured yet, but it _seems_ possible.

With tri-280's and a QX I think you're going to be asking a bit much from that Quad rad. You could probably optimise it slightly by placing the CPU directly after the Rad in your loop, but at the end of the day I think you're going to see a continual increase in water temperature under load as the GPU's pump in more heat than the rad can take out.
 
I have made the loop so that the CPU is first, I think you coul dget another 240cm behind the 480 but it would be very very tight and you could no longer place a pump down there I reckon
 
A pump res combo is good for small spaces but a proper res will even out your temps.

Place the CPU as the first block in the loop for best CPU temps.

If you find the temps are too much you may have to run a second loop for the CPU, that would need a double rad.

Like Jim said one quad rad won't cut it. I say 2 loops. One tripple rad for the gpus and a double rad for the cpu.

Get a decent pumps like a ddc and get a res top. Reliable pump and a res in a small package.

Not to take the jam out of your doghnut but tri-sli runs like a dog from what i have read.
 
Ok as I thought really, gonna run dual loops with a 240 xchanger (no room for a 360 and don't want a 360 in the roof, think it looks a little tacky) another ek res and ddc ultra xspc top to match the current cpu ddc ultra xspc.

cheers guys.

p.s Tri SLI gtx 280's is unstoppable, but overkill fow all except crysis

hopefully will get some pics up here if I ever get it done LOL

Thanks Guys
 
If you have the money go for triple but yer it'll only get you good bench scores and a playable game on Crysis MAXED

and max in future realeases...farcry2 looks demanding for example....but yeah nothing an SLI Setub or possible one GTX280 could muster I guess.
 
for best results run 2 loops one for the gfx cards and another for the cpu. that way u have planty of oc'ing headroom to work with
 
Hmm well 4x120mm rads which don't use tubes (like the old EVO series from aqua-computer) can handle roughly 1300W of heat, which is way more than any TRI-SLI and QX9770 cpu can push out. Also, it really doesn't matter much in what order you tube your blocks since the in and out temp differential ain't more than a few C's.. What you should do is make sure that you do tube things so that it doesn't look like a warzone in your computer. The ID of the tubes doesn't matter much for performance either, 1/2" ID system compared to a 8x1 (10/8 tubes) gave me allmost no benefit at all (no overclocking headroom difference at all).. Also you need to decide on what kind of tubing you want, push on fittings can be easier to bend around the case and don't require any sleeving to reduce kinks..

2 Loops are very good, if you can afford the extra stash both cash and space wise. 2 loops is more tubes and more mess..

3 SLI cards, if you're using 2 slot waterblocks you're making airflow more reduced than what it need be, aqua-computer have 1 slot blocks for most cards. Not sure how they work in a highflow 1/2" ID system though.

Also, Tri SLI currently have huuge issues with graphical glitches in several games, more so than quad SLI. But, you go with what hardware you've got, sounds like it's blazing fast.

What you can do though is use 2 cards for 280 SLI and the third for multiplemonit desktops (sli, trisli or quadsli only works on 1 monitor) and then you can add it (a bit of hassle but) when you need the "Tri-SLI" performance..

Theoretically it should be easy but I have a triple and and dual with Q6600 and SLI 8800GTXs and that I toasty at best and I have done the thermodynamics to maximise cooling as best as possible.

You can have that setup but you WONT hit 4GHz not by a long shot. 3.6GHz would be highest prolonged use (4GHz for suicde run only). You'll have to get inventive to keep that sort of hardware cool. Which IMO means at least two radiators and hopefully 2 loops which after doing my large WC setup in a TJ07 I can say you will have to be very small fingered and have a grip like a rock climber.
 
it was as a remark to RJwilson's Q6600 clocking :D

And why did you go with the 9770? 9650 clocks just aswell and costs quite abit less.. It's about preference I guess but..

I know thatnow lol would have had a qx9650 if i was more aware, impulse buy to be honest:)

Hrm.. Thought the Q6600 clocked well even on air.. ohh well :D

What would you call well? It will hit 4GHz not stably yet but I can play CSS. It is still toasty with my massive rads though so the 4x120 wont be enough for an even more mental setup.

Oh I didn't realise you have such little peripheral hardware so that will make it much easier to tube. Nice install too bit neon for my likes though.
