The chamber fan is terribly loud at 100%, which is the default speed for printing PLA on the textured build plate

I think PLA + textured PEI is a common use case. People complain about the noise on Reddit

Could the toolhead thermal sensor be used for closed loop control of the chamber fan? This would reduce the noise for customers operating in cooler climates

There is a chamber temp sensor that could be used for this purpose. I’m skeptical that the chamber fan has any useful effect on chamber temps, though, as it doesn’t seem to exhaust much air.

Or just alter the Gcode so you set the fan to 70% or so. It is barely noticeable at 70%.

While allowing us to set a “chamber temperature” and try and regulate it with the chamber fan would be nice I don’t think it even exhausts enough air to really matter.
