Given the sensors-detect output, looks like Winbond w83627hf.

Be more specific please.  Output from 'uname -a' will suffice.

[I ask this because there has been a lot of w83627hf driver work recently -
for 2.6 kernels this happens in mainline (as opposed to lm_sensors CVS).]

OK, could you please send the output of 'sensors'.

One more question... does your BIOS have any kind of automatic fan controls?
They are usually on the same BIOS screen that shows temperatures.
