Humming noise from heated bed, TEC 4

The TEC 4, can give a humming noise from the bed heater. Especially when it is near its setpoint temperature and the printer is idle.

The temperature controller quickly starts to control the temperature to an as stable as possible temperature. This switching happens at high frequency which is audible. This causes no issues. At the time of writing we are working on a fix to lower the noise level.
