Sometimes (during portupgrade or other high load) CPU temperature becomes very high, and laptop can shutdown due to very high temperature (more than 100 in Celsius). And CPU fan stops at such moments (or works at very small speed), but sysctl -a | grep "tz0.active" shows "hw.acpi.thermal.tz0.active: 0". What is also strange: if sysctl variable "hw.acpi.thermal.tz0.active: 1" I see that cpu fan is running. If in this moment I send "sysctl hw.acpi.thermal.tz0.active=0" than cpu fan stops. If I send "sysctl hw.acpi.thermal.tz0.active=1" I see that cpu fan works again. But I saw several times "hw.acpi.thermal.tz0.active: 0" and cpu fan worked at high speed. Is this problems with my hardware or with acpi? It seems that I do not face this problem when run Windows on this laptop. I will appreciate your answer!
