GPU temp reality check

post #1 of 6
Thread Starter 
Greetings,

I need a reality check before I go completly insane or do something stupid to my loop.

I'm running an i7 960 completly stock and a GTX 580 completly stock. CPU temps I'm fine with but the GPU idle temp seems a bit high at 40C.
I'm running a dual 180mm rad with dual Silverstone Air Penetrators in a pull config. My GPU block is the EK all copper block. My CPU block is a DT5 Noz. My TIM is Phobya HeGrease Extreme Thermal Paste.

Here are my temps:

Idle:
Ambient - 26.1C (Yeah, this room is an oven)
Rad IN - 33.1C
Rad OUT - 32.2C
CPU - 26C
GPU - 40C

Full load running Prime95 and Furmark for an hour:
Ambient - 26.1C
Rad IN - 38.1C
Rad OUT - 36.1C
CPU - 46C
GPU 50C

Should I stop looking at the temp monitors and get on with life or could this loop be doing better?

So you have a single 360mm rad?

If so, with that high of an ambient I would say the only way to decrease those temps is to add more radiator or a better pump.
A. What pump are you running?
B. In my personal op, i think your temps are fine.

Seems like the loop is doing great.

It's a dual 180mm. This one from FrozenCPU

http://www.frozencpu.com/cat/l3/g30/c95/s1551/list/p1/Liquid_Cooling-PC_Water_Cooling_Radiators-180mm_Dual-Page1.html

My pump is a MCP655 with a speed control. I've turned it down to 3.0 l/min but to doesn't make any difference if it's running at 1 l/min or 5 l/min.

Then I would say a GPU Reseat might net you 2-5c but otherwise your temps are fine.

Just depends how nitpicky you want to be thumb.gif

What you're saying makes sense as I redid my loop and part of it was applying the Phobya HeGrease to my GPU block. The grease didn't go on very well because as I spread it to cover the GPU and it seemed to dry out very quickly. It kinda turned gritty and clumpy... (lack of a better description)

It wasn't like some of the other thermal grease I've used in the past where it stayed semi-fluid even after years of use.
