Acer C740: pch_wildcat_point-virtual-0 Unusually High Temperatures

[jasonmerc]

I'm running Firmware 4.12 from MrChromebox's repo for my Acer C740. Totally stock chromebook hardware wise, other than a 128GB SSD I put into it. For some reason, when running "sensors" on my Kubuntu 20.04 install it shows "pch_wildcat_point-virtual-0" running at an extremely high temperature. Everything else is normal, 40-50C. This wildcat thing though can go above 100C easy.

Here is copied output from the "watch sensors" command:

_**coretemp-isa-0000 Adapter: ISA adapter Package id 0: +44.0°C (high = +105.0°C, crit = +105.0°C) Core 0: +43.0°C (high = +105.0°C, crit = +105.0°C) Core 1: +43.0°C (high = +105.0°C, crit = +105.0°C)

BAT0-acpi-0 Adapter: ACPI interface in0: 11.54 V curr1: 447.00 mA

pch_wildcat_point-virtual-0 Adapter: Virtual device temp1: +95.0°C

acpitz-acpi-0 Adapter: ACPI interface temp1: +42.8°C (crit = +104.0°C)**_

I don't understand what could be causing this. No part of the chromebook feels hot. I even applied fresh thermal paste to the heatsink. If any other logs are needed please let me know

EDIT: Just to clarify, I'm posting this here because it appears others have had similar issues when flashing custom firmware: https://www.reddit.com/r/chromeos/comments/cvrnai/chromebox_high_temperature_after_flashing/

I'd guess it's a kernel bug, otherwise a coreboot bug. Either way it's nothing to worry about

FWIW, same here with an ASUS Chromebox 2 (CN62). It reports 90+ degrees all the time. Moves a little with system activity, but not much. Ohter temps look okay.
