    I would contact support.  I am not sure if it has to go to zero before it warns that there is an issue.  

    Can you see the fan?

    hi ccku


    Support won't be able to make much of a determination beyond the suspicion that perhaps this fan is starting to get sticky and rotate slower and may eventually fail.


    We do not implement independent fan speed control so they should all at about the same speed, you have grounds for an RMA now, but if it's not causing increased temp, perhaps keep an eye on it and if it keeps going lower then consider RMA during a maintenance window.
