I always start by blowing the dust out of the fan vents. Yes, I know "Windows works fine", but please start with that. Your machine is sufficiently old that if you've never done that, it's probably time anyway. Next: 1. build with ACPI_DEBUG on (acpivar.h) and acpi_debug set to something more than 20. 2. Watch for acpitz messages in dmesg as your fan changes speed (or doesn't). Note that enabling that debug level will lead to a ton of spam in dmesg, you may instead decide to just set the dnprintfs in acpitz.c to regular printfs (especially those in acpitz_setfan and acpitz_refresh) in order to avoid seeing unrelated debug messages from elsewhere in ACPIland. -ml > > OK, now some info: > > =========================== > $ uname -mrsv > OpenBSD 5.7 GENERIC.MP#881 amd64 > =========================== > > Taken immediately after boot (I just noticed the itherm0 temperatures > were broken at that time...).
