I am experimenting with different clocks on the 8800GT. My case doesn't have the best cooling (Only one low speed fan that runs air through the cpu heatsink), and I'd like to know if having a fan right next to the card would interfere with/damage the card.I know hard drives are sensitive to that stuff, but I've never tried on any type or card before.

Crysis Benchmark with fan: 71 degrees
Crysis Benchmark without fan: 82 degrees

I've never heard of a graphic card being adversely affected by a regular case fan, so I think you're safe.

Your best bet of course is to install a 120mm fan in both the front and back, pushing air from the front to the back.

Your gpu should have a fan installed that pushes air out the rear socket.

Of course, if you've got more than a couple hdds, I'm always leery about moving air from the front (since the hdds get hot).

If you have a top fan or a side fan, best make those intakes and have the front and back fan outtakes.

for crysis & an 8800 those temps arent too bad (a shade warm)
make sure the fan is ramping to 100% duty cycle in games. 8800 will kick the bucket at around 92-95c

I am using riva tuner 2.06 and a custom set of fan profiles (low level) thru riva's background gpu monitor. works well but I want to code my own solution and build it as a windows service, or hope nvidia fixes the auto fan settings in the drivers - which ever comes first.

Since the 8800GT is a single slot card, the only cooling it has is the small fan, which isn't enough. Anywhere wast 49% and that fan just sound horrendous...

lol, guess I'm only familiar with the 8600gts (mine took up two slots and had a large fan on it), which I thought would be similar :o)

Someone told me you could overclock in RivaTuner 2.06, but I can't find where to.. Could someone direct me to where it is?

Thanks!
