Hi Guys,

Please can you help me with my heat issues... i have 3 GTX 285's in Tri Sli currently in a Lian Li ARMORSUIT PC-P80B case and they get rediculously hot... its not a case airflow issue as i have had the side off with a desk fan blowing onto them and they still hit over 100C in OCCT. So watercooling it is !

Could you guys possible suggest which parts to buy/would be compatible as i do not want to buy the wrong things, i am obv reading up on all the watercooling jargon but just eases my mind if i have some advise from the pro's :) plus not many guides on watercooling TRI SLI set ups.

So i need to watercool Tri Sli BFG 285GTX OC2's and might as well watercool my i7 CPU while im at it.

Please let me know what you think will work best.

Many Thanks !!!

Big radiators. Several of them. What can you fit in your case?

Dual loops is the sensible route here, or leaving the i7 out of the loop. A laing ddc 18W with xspc top and whatever radiators you can fit.

You can of course put the i7 in the loop as well, with two loops it doesn't really matter if the water temperature is 40 degrees or so. Graphics cards are happy with higher temperatures than processors, hence two loops
 
2x PA120.3's for duel loops.

i7 and 1x 285 on one loop.
Other 2 285's on the other loop.

I would go with 2x Laing DDC 18W pumps, but with the ResTops, as its easier than 2 bayres'.

Then just tubing blocks coolant barbs etc..
 
thanks to everyone who replied/advised, helps a lot ill do a little more research and post back with what im going to buy just in case i make some noobish mistakes.

Hey mate, yeah it got shut down after all the flamers/trolling lol

Yeah build going well, just need to sort the heat issue out as those 285's get real hot in crysis and i want to see how far i can push my i7 too :D
 
EK GTX 285 SLI Plexi x3
EK Supreme i7 Clear
Thermochill PA120.3 120mm Triple Radiator x2 or 120.3 + 120.2
XSPC DDC 18w Ultra Pump/Reservoir x2
And the tubbing ect.Do you wanna cool nb and sb as well?IF so,then dependly what motherboard you got look for dedicated set from Ek.

looks like heatkiller blocks are the way forward, they seem to have better performance than the EK blocks. They do some nice GTX295 blocks also but i think you have to have them parallel rather than in series if cooling tri sli.

Can anyone explain to me the pro's and con's of this ?

Cheers,

I think if you had a powerful enough pump then it would be fine to run your GPU loop in series. The actual temperature throughout the loop will be the same, it's the flow rate that you need to worry about.

Obviously if you were to split it up and have, say, one GTX within your CPU loop, then that would raise the overall temp of the loop and perhaps effect your overall CPU clocking.
 
cool so think ill go with the 3 gpu's in 1 loop and the i7 in the other. Ill use 2 Thermochill PA120.3 120mm Triple Radiators some Masterkleer 7/16" Tubing - 1m with PrimoChill ICE Non-Conductive Coolant (32 oz.) - UV Brite Green.

only thing left to do is decide on HeatKiller or EK Blocks :D

and also the pump i reckon XSPC DDC 18w Ultra Pump/Reservoir x2 (just can someone confirm i will not need to by a seperate reservoir with these pumps ? Im assuming not but some of the reservoirs seem huge so not sure if it will be enough with the pump/res combo's...)

Thanks Again !
