evga 8800gts 512mb heat issues

post #1 of 14
Thread Starter 
Ok, this is my first SLI rig, so maybe I'm just being paranoid. But there is literally about 1-2mm (millimeters) between my two 8800s. This gives one of my cards almost no "breathing room", quite literally.

In HWMonitor the bottom card (which has a couple inches of clearance), is 61C idle, and the top card (which has 2mm of clearance from the fan), is 66C idle. These temps seem pretty high for idle. My 7900 in my laptop would hit 66C at full load, and it was OCed (in a frickin' laptop!).

How do I cool these things down, I'm afraid to even run 3DMark06, I predict about 80C load, maybe even slightly more.

EDIT: I should add my e8400 is idling around 39C right now in the case.

You will be fine bud. What precentage are you running your fans? my tri-sli board leaves plenty o' room between the cards, and I have aa lot higher idle temps at stock fan speeds. Your cards seem to run cool...

What is a good program to set video card OC/fan settings? Riva Tuner seems to be missing all those features for whatever reason. I've read it was great, but I downloaded it and it has no temps, no fan speeds, nothing...

Seriously RivaTuner seems vacant. Here is what I'm seeing when I open it.

Main Tab: Lets me setup multiple monitors, look at driver settings.
Settings Tab: Set if it goes in the tray, always on top, language, startup settings.
Power user tab: Change registry settings
Launcher: setup program settings
And about and links, that is it.

Thanks again, I guess RivaTuner wasn't recognizing the new GTSs. I also found a complete RivaTuner guide from another thread on here, got fan speeds setup properly.

Oh, and +rep

80, even 90C load won't harm the cards. In fact they will probably work quite happily at stock speeds at such temps.

Still with the stock cooler, in a moderatly well ventilated case, you should have an idle temp of 55C, give or take a few degrees. Does seem to be some serious crowding.

A cheap fix is to grab an extra 80mm or 120mm fan and just sit it on the bottom of the case blowing directly onto the cards. It lowered my 7950GT 5 degrees at idle and 8 degrees under load.
