Print head fan griding at start up

@Rainie - I already tried tapping on the controller unit and the fan noise is still present which indicates that the fan is faulty. Why can’t you replace the controller for me as the noise is too unbearable when using it for long periods at a time. The noise is even worse that the 2 fans on the 3d module.

Can we get the full part spec? What is the pin, wire length, etc. . .

@NilartPax Hi ,Which part do you mean?

The bottom fan on the printer module.
