https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=233764 --- Comment #15 from Conrad Meyer <cem@freebsd.org> --- (In reply to gosha-necr from comment #13) > pciconf -r pci0:0:24:3 0x64 > 72240005 HTC_TMP_LMT: python3 -c 'print(((0x72240005 >> 16) & 0x7f) * 0.5 + 52)' 70.0 I.e., 70 "°C" in whatever scale Tctl is on is "max," I guess. Given that seems low, there is probably an offset on that scale. I don't know what it is, and the Power and Thermal Document does not seem to be published :(.

It seems like the total offset can't be much more than 5-10° since 100°C is quite hot for a CPU. But given HDDtemp of 28°C, I don't know. That'd suggest 17°+ offset, which makes for a throttle at 107°+. Extremely hot. -- You are receiving this mail because: You are the assignee for the bug.help
