Re: 6600 GT AGP and TEMP
Before I had 72 deg C on my 6600GT card with the standard fan.
I removed the fan and heatsink and re-fitted it, and it dropped to 63 deg. With the same components.
Probably the wacky mounting of the heatsink (it is just pulled to the circuit board using two plastic pins) results in poor conducting of the heat from chip to heatsink. No matter how much fan you mount on that, the chip will still run hot as a result.
