>Release:        FreeBSD 5.3-BETA7
>Organization:
>Environment:
Stock FreeBSD 5.3-BETA7 ISO Disk 1, i386
>Description:
FreeBSD is disabling the fan causing the system to overheat and shutdown. 

hw.acpi.thermal.tz0.active=0
>How-To-Repeat:
N/A.
acpi0: <COMPAQ RSDTBL> on motherboard

>Fix:
set hw.acpi.thermal.tz0.active=1 in /boot/loader.conf and reboot, but then the fan is always on (unless you manually set hw.acpi.thermal.tz0.active to 0). the other option would be to disable acpi.
