A10 part cooling fan

[iherbak]

Hi,

I have a rev b A10. My part cooling fan stopped working.
If i measure the voltage when it is at 0% it reads 24.3 but when i put it to 100% it reads 19.3.

Any idea what has happened?

Thanks

Hi，is the cooling nozzle fan not rotating?
You can try to toggle it by hand to see if it is caught by a foreign object,
or you can try it by replacing an interface on the adapter board.
