Need cooler temps in loop.

post #1 of 19
Thread Starter 
I am running 2- 480's OC to 800/1600/1900 and a 260 stock. All have EK blocks. NB/SB Black freezer and a Apogee XT for CPU.
I have a black ice 480 and a 240 pull config. in a 800d case.
mpc 655 pump

My temps were running in the low 60's when folding until I added the 260. Now they have jumped up 10c. And I turned the cards down from 900 with lower voltage and the CPU back to stock from 4.4.

260= 69-72c
480= 68-71c
480= 54-58c
cpu= 57c
room temp is about 21c

I know 70c is not that bad for the heat I am generating, but I want to crank things back up and leave them for a few days while folding.

My question is... would I see a difference in temp by adding another rad ?
I only have room for a GTX 92 or 80. I want to keep everything inside..

Thanks...

Can you add some fans for a push/pull config? What fans are you using currently?
You can change your fans out for ones with greater static pressure and cfm output.

GentleTyphoon 120 mm @ 1850rpm when folding. rated air flow = 98 m³/h
I only see a 3c temp drop from the fans being @ 50% vs 100%

whats your water temp under load (after 20 minutes)? Would be good to see what your temperature delta is between ambient and water temp - that way we can see how much you'd benefit from another rad

Are the GPU blocks connected in series or parallel? If they are connected in series you definitely have a restriction problem that's causing laminar flow. The CPU block and radiators are some of the most restrictive blocks around and the 655 isn't that powerful of a pump so it could be having trouble.
