RN104 'Fan System in enclosure Internal speed is below threshold. (0 rpm)' message
Hey all, This morning on my RN104 I got the error message "Fan System in enclosure Internal speed is below threshold. (0 rpm)", However the fan is running flat out, sounding almost like a hair dr...
It sounds like the tachometer signal from the fan isn't working. Obviously, use warranty replacement if that's an option. Otherwise, hopefully, it's the fan itself and a fairly easy fix by replacing it. If it's the monitor circuit, there's nothing you can do save add a "pad" that lowers the fan speed (but does nothing to correct the NAS's ability to monitor or control the speed).
Welcome to the Community!
Do you notice if there's a change in the temp of the NAS itself? or the drives might be running hot.
If you still have warranty on your RN104, which is 3 years it is best to contact Support so they can issue you RMA if needed.

Hey Marc_V
Thank you for your reply.
Both drives are maintaining a steady 19 to 20 degrees C (68 degrees F).
The CPU temp is a pretty steady 34 degrees C (91 degrees F).
I no longer have warranty on this product so I am happy to do whatever is economically viable to repair it.
Cheers,
Lawrence
