Hi, the motors and the computer of my polargraph getting hot while drawing. Is it advisable to cool them with fans or does it not matter?

They'll get a little hot yes. They heat up quite fast particularly if the motors stay locked in position, still.

They can be tuned to run weaker but cooler (http://www.polargraph.co.uk/2013/02/tuning-stepper-drivers-for-strength-and-subtlety/).

Adding fans does no harm but I've never needed to. Sometimes I stuck heatsinks on the motor drivers, but it was for looking neat, not because I needed it!

The motors get less efficient as they warm up, which is why a small buzz usually gets louder.
