You did not mention your version of FreeBSD. I think, I have seen this
problem in 5.x and then doing 

sysctl hw.acpi.thermal.tz0.active=0

followed by

sysctl hw.acpi.thermal.tz0.active=-1

was the workaround.

I am running -CURRENT now and I don't see this problem. However, ability
to force active cooling level seem to disappear as well ;)

Output of

sysctl -a hw.acpi.thermal 

right after boot will help as well as your ASL dump (see Handbook for
directions on how to get one).
