Venice A64 939 runs super cool?

Archived from groups: alt.comp.hardware.overclocking.amd (More info?)

I heard that the 90 nm A64 parts run cool, but I didn't expect this.
Motherboard monitor and the MSI util 'Core Centre' both report idle CPU
temps lower than or equal to the case temp, typically around 20-25
degrees. Granted its winter here and room temps are usually around 17
degrees. Cool 'n' quiet is not enabled. Temps are only a few degrees
higher under load.

MSI Neo2 with Venice 939@2400Mhz.
Thermaltake Silent Boost HSF (Cold to the touch)

Is this what other people are seeing?

Yes, but they are not. Under load the CPU temp climbs above the case
temp by a few degrees. A very cool CPU. The HSF is cold to the touch,
even with the fan cranked down to half speed.

what board you running with that 64 3000???

The only way the CPU temp can be less than the system/case temp is there has
to be something creating lots of heat very near the case temp sensor.
We're all on the same page that there's no air cooling that can make the CPU
temp lower than it's 'ambient' - yes?

Well, forced convection, aka wind chill is what cools the cpu below the
case temperature. This is only possible because the 90nm parts run so
cool in the first place. Once the CPU is under load its temperature
climbs above the case temperature.
