Well I guess the crucial question has already been asked, though not
answered by you if I am not mistaken. Do you run the SMP kernel, or do
you not? If you are running a kernel without SMP support, your second
CPU will not get any load, and by there not get as hot, which could
explain why the fan is running slower.

I am not sure whether this is totally correct though. I am not an
expert in this matter.
