Title:
  Fans switching on and off every 10 seconds after update to kernel
  5.8.0-34

Bug description:
  After updating via apt dist-upgrade from kernel 5.4.0-59 to kernel
  5.8.0-34 the fan on my machine started switching on (for an instant)
  and off every 10 seconds even when idle with CPU at 48/50°C.

  Switching back to previous kernel solves temporary the problem, i.e.
  fans are always off with light desktop work.

  The new behavior is really annoying and I guess not healthy for the
  fans.

  I'm on latest Dell bios, with every other package updated.

  Di something in the thermal policies change between those two kernels?
  Is it possible to go back to previous behavior ?

  Thanks in advance for help
