Your description is somewhat generic, so the best I can do under the circumstances is to give you a generic suggestion. Add something like hw.acpi.thermal.tz1.passive_cooling=1 hw.acpi.thermal.user_override=1 hw.acpi.thermal.tz1._PSV=75C to /etc/sysctl.conf and reboot. Please, note that on my laptop, relevant thermal zone is TZ1, which might or might not be the case for you -- if it is not -- change tz1 to whatever is appropriate. If this does not work, things, which are needed to help you further, include: 1. output of uname -a 2. output of sysctl hw.acpi.thermal 3. output of sysctl dev.cpu 4. output of grep powerd /etc/rc.conf 5. output of sysctl dev.acpi_ibm It would be good to have output of (#5) from several points under the load. Also, please, consider following advice on cleaning up dust and possibly re-applying the thermal paste given elsewhere in the thread -- on my 2-year old laptop doing both shaved about 3C from the normal operating temperature.
