Public bug reported: I installed an update yesterday, and since then the fan on my T420 started spinning at the highest speed all the time.
I see that the two/three last updates included acpid and linux-image- generic. I noticed this with BIOS 1.34 an upgrade to the latest 1.36 did not help. Setting options thinkpad_acpi fan_control=1 also did not help.
