I have an EVGA 8800GT KO OC Edition GFX card. I noticed that it was quite hot to the touch (It also kept crashing when I was playing Fallout3, so I thought it could be a hardware issue) so I downloaded SpeedFan to see the actual temperature. Here are the results:
That's idle, not full load. I'm using RivaTuner but I have no way of telling whether or not it is working. I've set it so that if it reaches a temperature above 76 it will turn onto 100% fan speed. If I keep the fan speed at that level the temp drops down to 65C, is that ideal for idle? Under full load the GPU at 100% fan speed is at 75C.
I am still getting crashes to desktops whenever there is the slightest hint of the GPU having to work harder... is there a solution to this?
Psh, last night I had to rip my 8800GT out of my computer. I was trying to play Neverwinter Nights 2 with my 4830, and I started getting visual artifacts, so I wondered what was up. I checked Speedfan, and the 8800 was sitting (idle, as I wasn't playing on that monitor) at 88c, which I think was a wee bit much for just sitting there smothering my 4830.
I burned my fingers trying to get it out.
I'd suggest an aftermarket cooler. Zalman's VF1000 and VF900 are good choices, but make sure to buy a set of mosfet sinks as well, as the Zalman's only come with enough sinks for the RAM.
