The issue seems to be = OS (FreeBSD) dependent. Context:=20 I am moving from Linux to FreeBSD, and when I first booted the FreeBSD 13.2-RELEASE DVD, I sensed a lot of unusual heat emanating. The heat persis= ts even after installation and it heats up again as soon as the installed syst= em is rebooted from a complete state of cool down and rest. This happens with = both when using the live DVD and after a freshly installed system, tested on both 13.2-RELEASE and 12.4-RELEASE. Observations: - This issue seems to be OS-dependent and it is noticeably cooler in Linux.= I confirmed this by reinstalling Linux to verify and installing freebsd-13.2-RELEASE again. - It's not just the different reported temperature, I can actually feel the heat, that's when I first noticed and decided to test further.=20 - Changing dev.acpi_ibm.0.fan: 1 -> 0 and dev.acpi_ibm.0.fan_level: 0 -> 7 settings did not do any good. - Powerd is enabled and running and seems it has no influence. - The issue persists both with and without acpi_ibm loaded. - The temperatures in Linux varies from 43-48 C, while FreeBSD temperature ranges from 53 to 59. This is mostly with CPU @~100% idle.
