I tested Q-Fan earlier this week:
K8V, cheap OEM HSF, 3200+
Q-Fan on, system idle: The temp ocillates between 43C and 52C (This
happens at 4-5min intervals)
Q-Fan on, system under load: The temp tops at 61C, then falls to 48C
Q-Fan off, system idle: 36.5C
Q-Fan off, system under load: 48C
It looks like there are only two fan speeds... The 9C variance at idle
with Q-Fan turned on can't be good for the long term life of the CPU,
since I've heard that thermal expansion and contraction are bad for CPUs...
I run my box 24x7 doing scientific calculations, so Q-Fan really doesn't
matter for me... I do plan to get an Alpha 8150 HSF this week though...
Note that the numbers I listed above were with Cool'n'Quiet disabled...
