Cooling solutions for eVGA GeForce 8800GTX

post #1 of 8
Thread Starter 
What I was wondering is if I go to overclock with RivaTuner will my card be cooled properly by the stock cooling? My Idle is like 52C and 60C max on full load.

If so does Zalman or anybody have *good* cooling solutions for the 8800GTX?

Anyone here have any experience overclocking the 8800GTX?

Well i have an 8800 GTS 640mb, so i'm not to far from your situation.

60C load is fine, i don't remember the exact number, but i know they can go higher.

First work on your case airflow if at all possible, those things need fresh air.
If that doesn't work or is not possible, then go aftermarket cooling.

Or you could reseat the heatsink with some AS5, that normally drops temps a degree or two.

Your temps are better than my GTS. I idle at 54C and load temps of around 72C with 100% fan speed with Riva Turner.

Supposedly, few GPU coolers cool better than the stock G80 cooler, and those few only win by a degree or so, even if they might be quieter. The new Zalman VF-1000 (I think that's what it's called) is supposed to be better, but who knows.

I've tried several coolers for my 8800gtx, including stock, stock plus slot cooler, thermalright HR-03 plus, and finally the Swiftech MCW60

My temps were:

Stock
Idle 60C
Load 83C

Stock + Slot Cooler mod
Idle 55C
Load 83C

HR-03 plus
Idle 42C
Load 52C

Swiftech MCW60
Idle 38C
Load 42C

I've also increase my GPU overclock from 626/1000 with the slot cooler, to 655/1000 HR-03, and still testing with the MCW60 but up to 670/1000.

So in the end I'm really suprised how lowering the temperature continues to increase overclockability. I figured I'd have to have it volt-modded to get as far as I have....nope





Just got my PSU this evening, so I've been busy installing and testing. Anyhow my vote goes towards the Swiftech MCW60, I think it probably cools better than the full coverage blocks.

There seems to be a lack of products out there to cool the GTX. I looked awhile and gave up, finally decided I'd cut 2 holes in the side of the case and mounted 2x 120 high cfm fans pointing at my GTS. Temps dropped more than 10 degrees celcius. Currently surfing at only 48C. Haven't seen it reach 60C even after hours of Oblivion (while oc'd).
The fans also lowered my chipset temps by about 5C. 2x fans approx. $20., best investment in my case.
