My case temps have increased by 5-6C (with both sides on) ever since i've upgraded to my new rig. I know the 7800GTX runs hot 24/7, but I never really looked into it.
So I install ATI tool, open up the nvidia drivers settings to look @ the temps, record the idle temp, then run ATI tool for 5 minutes.
7800GTX @ 470/1270, stock cooling
Idle - 41C
Load - 82C
That kinda scared the crap outta me. I know the card can handle that, but its still a concern to me.
So I pick up some rubber bands and a cheapo 80mm fan. I take out the gtx, and try to think how i can mount this 80 on there. I took off the plastic cover, and placed the 80mm fan there. But...I couldn't find a secure way to keep the card there. The rubberbands kept slipping.
This stumped me for a little while until I realized that the stock amd fan was a smaller size, and pushed a decent amount of air. So I look through my computer boxes and find the stock amd heatsink/fan, and take off the fan along with the screws.
What great luck, you can screw that (70mm?) fan right into the fins of the 7800gtx's heatsink, right above the core.
So with the stock 7800gtx fan blowing air towards the core, and this 70mm fan blowing down at it, its being cooled from two angles.
I boot my pc back up, and get the nvidia drivers and ati tool setup.
7800GTX @ 470/1270 w/ 70mm fan added
Idle - 38C
Load - 59-60C (it wouldnt stay @ 60 for more than a few seconds)
I got excited, so I put the clocks back up to my benchmark clocks
7800GTX @ 490/1320 w/ 70mm fan added
Idle - 40C
Load - 59-60C (happened again)
Load after 20 minutes - 58-59C
After 90 minutes - 57-58C
After 8 hours and 14 minutes - 57-58C (GTX @ 490/1340)
And to think I still haven't put on AS5 yet
whats really cool is that my temps are almost as good as the 7800gtx w/ nv silencer 5, rev3. Only 1-2C warmer than that, woot!
PICTURES WOOT!
