There's no way in a month of Sundays you'll reduce your GPU remps by 10-15degC by putting the rad before them. 2-3degC tops at max load.
Proposed water cooling project STH10
- Thread starter Kropsky
- Start date
Not yet Schizo - saving for it. Will order at end of the month. How about your build? Any pics yet?
To get the best temps you'd be better off complicating the loop by going:
Res
Pump
Rad
CPU
Rad
Gpu1
Gpu2
back to Res
Your rads will remove pretty much all of the heat that is in your rig by the time the fluid has passed through them, most of the heat removal will have happened after passing through just ONE of them. The temp delta will be negligible over the second rad.
If you aly them out as I suggest, then any heating done by the CPU will be removed by the rad, then the GPU's will receive COLDER fluid to cool them, resulting in lower GPU temps.
If I make a rough guess at the temp throughout the loops:
Res - 44
Pump -45
Rad - 30
CPU - 70
Rad -30
Gpu1 - 42
Gpu2 - 45
back to Res
Using your layout I'd guess the temps would be
Pump - 30
res - 30
Cpu - 70
Gpu1 -55
GPu2 - 60
Rad1 - 30
Rad2 - 29
Back to pump -30
The temps may or may not be accurate, but they reflect what is happened. How do I know? I went from a loop like yours to 2 loops and this is exactly what I saw.
Now mine is
res
Pump
phobya 360 rad
CPU
Swiftech 120 rad
and back to Res
and
Res
Pump
Swiftech 2.120 Rad
GPU1 (GTX 480)
GPU2 (GTX 480)
Swiftech 2.120 Rad
and back to Res
Get a colder feed into you GPU's.
Admittedly my GPU's not a Socket 2011, but it is an i7 950 @ 4.2Ghz on 1.45v 24/7 folding.
My heat exchange must be quite efficient because I've not had the heating on in my room now for 3 years. I sometimes leave my door open to warm the rest of the house...
Thanks for this.
Yes, I will be going res-pump 1 - pump 2) rad (top) cpu- gpu1 - gpu2 - rad 2 - back to res. I have opted for x2 pumps for later upgrades and in case of failure. One pump will be in bottom (for priming the system), the other in the top chamber. There is an issue with gravity I suppose, pumping styraight upwards, but this is mitigated by pumping water downwards as well, so hopefully that'll be OK.

I must say that is wrong in so many ways!

OP
Running blocks/RADs in Parallel will reduce the restriction and improve the flow in many loops.
having 2 loops vs single loop is not a better way of having a loop.
Liquid will come to its equilibrium over time - so putting a RAD before a block will not reduce the temps of a block after that!
GTX480 is a good RAD but prepare to run your fans at speeds over 1000RPM for better results.

Hi. I was going for single loop but with two pumps. Pump 1 down below, going to pump 2 on top, which then goes to rad 1 up top (480), then CPU, GPU1 and GPU2, to another rad below (560), finally to res. No good?

Your loop confuses me a bit! Can you update the case diagram?
Compression fittings in my build log are EK 1/2"ID 3/4"OD PCS fittings(But soon to be changed)
I run GT fans on my GTX480RAD as well but have to ramp up the speed over 1000RPM when gaming(I just put it on 100% as they make little noise for me)

OK. I'll try and be clearer.
I want to have a pump in the bottom chamber of the case, which will connect to a pump in the top chamber of the case. From there, I will connect this top pump to a radiator (480) also in the top chamber. This then leads down to the CPU, which connects to the first and then second GPU. The loop then continues down to the second radiator (560) in the bottom chamber, which in turn connects back to the reservoir (in main chamber).
Basically, I wanted two pumps both to cover failure of one, and for future upgrades or additional watercooling. I have to have a pump below the res to prime the thing, and I thought by having a pump in the top it will help with pressure.
Hope that is clearer.

D5 can handle over 3 meters of head pressure(3.1 - 3.7m). So you will be fine with just 1 x D5 for those blocks and RADs, but if you need the redundancy and all that another D5 would not hurt!
