re: HSF temperatures: Athlon64 FX Temps.

Default Settings
2.2GHz w/Retail HSF 2.2GHz w/Venus 12
Idle: 37 Degrees C 31 Degrees C
Load:
51 Degrees C 42 Degrees C
Case Temp :
33 Degrees C 31 Degrees C

These don't seem to cool to me...

Well, a good HSF can achieve about 0.3 degC per watt. Intel is targeting 0.23 degC per watt for its new Prescott fans. Under full load, the Venus 12 had an 11 degree rise in temperature from case temperature to CPU temperature. That implies it was dissipating 11/.3 watts, or 37 watts.

Even if we assume that this new Venus fan is achieving Intel's Prescott design spec of 0.23 degC per watt, the Athlon 64 FX was only dissipating 48 watts.
