Catalyst 9800-L-F fans failed after upgrade

[ppnlr]

After upgrading the 9800 from 17.9.4a to 17.9.5 an error appears:
*Sep 10 13:08:16.163: %CMRP_PFU-3-PFU_FANS_DEAD: Chassis 1 R0/0: cmand: The fans in the FM in slot 1 have all failed.
upon observation, I think the fans stopped, although if the device reloads, you will hear it running. I'm trying to rollback the version but I think the device reloads due to excessive heat.

I just turned off the device to cool down..then turn it on again and the error didn't reappear. tried to upgrade the software again just in case that's a bug.

  - Note that even in that case it can be useful to checkout the health of the controller
