I'm sure if you did that it would be louder than a VF900 on minimum. The stock fan is small and shallow, it's not going to shift any serious heat.There's nothing wrong with the cooler people just don't turn the fan up.
Modest overclock - core 656 mem 946 - max temp recorded by ATI tool while running Crysis was 58 degrees. Any suggestions for how much further I should push the clocks anyone?
