Description CircleCode 2017-04-04 08:05:48 UTC

hardware: thinkpad X1 carbon 4th gen (type : 20FB)
OS: Arch linux
kernel: Linux R2D2-X1 4.10.6-1-ARCH #1 SMP PREEMPT Mon Mar 27 08:28:22 CEST 2017 x86_64 GNU/Linux

after wake up from suspend, fan goes at full speed and never goes down.
Even a restart is not sufficient to stop it, I must switch laptop off and on again.

Temperatures indicated by lm_sensors are low and do not explain this speed.
