K1 rear exhaust fan

Is it possible to control the speed of the K1’s rear exhaust fan with Creality Print?

Welcome to the Creality Forum @ObieWhistler

How do you want to control it…??

I know there is a section in the slicer where you can control cooling in Creality Print.

Also on the printer itself there is a control for the back fan.

I should have been more explicit. I would like to be able to set the rear fan speed in the profile on the “prepare” page. The cooling profile tab has controls for the extruder fan and the CDS fan, which I assume is the side blower, but it only has an enable for the chamber cooling fan, which I assume is the rear exhaust.
