Hi - My mac pro is giving me some trouble. The intake and exhaust fans are registering zero rpm (istat pro) but can be seen spinning and sound like they are at >1000rpm
It was really dusty inside - now cleaned up using compressed air. Just after the exhaust fan started registering and seemed to be functioning normally. Since it has reverted to a zero reading.
Is there a sensor on the board to clean?
I have tried SMC reset. Thanks
