https://bugzilla.kernel.org/show_bug.cgi?id=210457 --- Comment #7 from Thorsten (s-cvhajmmblfsofmpsh@xxxxxxxxxxxxxxxxxxxx) --- Probably it's the same issue. However, here we know that the main issue is that the first entry of /proc/acpi/ibm/thermal is erronously -128 some (or most) of the time (so the fan is just a symptom, not the issue). temperatures: -128 -128 0 0 0 0 0 0 0 0 1 0 0 0 0 0 Iirc, the first entry is /sys/devices/platform/thinkpad_hwmon/hwmon/hwmon*/temp1_input (By the way, the second entry being -128 is fine) -- You may reply to this email to add a comment.
