Hi@ster,

1.Impact on the system

The board temperature is too high.

2.Possible cause

Fan failure, such as stalled.

3. Processing steps

Run the display fan command to check the current fan status, check whether the fan board is registered and whether the speed of each fan is zero.

If it is not registered, please reseat the fan board once and see if the problem disappears.

If the fan speed is zero, replace the fan as soon as possible. Hope to help you!
