Among other startup scritps in my laptop, I use this for setup the temperature threshold:

root at camibar:/root # cat .setcooling.sh
#!/bin/sh
sysctl hw.acpi.thermal.user_override=1
sysctl hw.acpi.thermal.tz0._PSV=65C
sysctl hw.acpi.thermal.user_override=0

Default value is 101C, which I think is excessive optimistic value.
