CRS317 fault led ON running ROS

RouterOS General
1

Hello, have a couple of CRS317 running latest betas and on one of them fault LED is constantly on.
On the device with fault led OFF the output of system health print is:

[admin@MikroTik] > system health print 
  cpu-temperature: 36C
       psu1-state: ok
       psu2-state: ok
       fan1-speed: 0RPM
       fan2-speed: 0RPM

on the device with fault led ON the output differs:

[admin@MikroTik] > system health print 
  cpu-temperature: 31C
       psu1-state: ok
       psu2-state: ok
       fan1-speed: 0RPM
       fan2-speed: 0RPM
       fan3-speed: 0RPM

When running swos the fault LED is OFF on both devices. Is there any way to find out why the fault led is on or turn it off completely?

Suffering from the same problem. Fault LEDs are running without any reason. After restart switch then Fault LED gone for some time.

quick answer to myself

/system leds set 32 disabled=yes

This was a small error in the firmware.If you are on a recent firmware do:
/system health detect-fans
and let the system reboot
That will get rid of the fake fan3, and the fault led condition
