Hi,

Anyone have seen fan turned-on in 90% of the time?

I see that fan power-on when processor is up than 45?C and power-off 
when is under 45?C.

Temperature difference between 2 cores is 5?C in idle (Core1=45?C and 
Core2=40?C)

Local temperature is ~25?C, kpowersave is in "dynamic mode", my 2 cores 
(Intel T7500) is running 94% of the time in idle (checked with "top"), 
with clock in 800MHz.

The fan speed is ~2600RPM (always under 3000RPM), and I think that is 
not enough to cooling the processor, because is necessary 3min to 
decrease 1?C in Core1 and only 40sec to increase 1?C.

I think that is necessary a higher fan speed.

I see this in Debian Lenny (2.6.26-1) and 2.6.28.8 kernel... Maybe in 
other versions too.

Regards,
Renato
