Eventhough I can hear the fan running, every userspace interface I have poked seems to say it's at 0RPM. /proc/acpi/ibm: status: disabled speed: 0 level: 0 /sys/devices/platform/thinkpad_hwmon/fan1_input: 0
This is true also for Thinkpad edge 530. They changed once again the EC config it seems. This bug is likely a dup of bug #43048 If someone want a tester or would just mind to explain me the basis of this stuff so I can just write it myself, make a whistle.
*** Bug 43048 has been marked as a duplicate of this bug. ***
Also affects Thinkpad E540.
