Part cooling fans not winding up...

Printer Model
Hi, blind guy again. I'm getting dreadful prints, and noticed that the part cooling fans on either side of the head don't appear to be winding up. I've got a Revo hot end and the it's direct drive.

I have a couple of questions:

1. Aside from using the k Klipper web interface to turn up the part cooling fans, are there any other tests I can do? I did use some GCode, M something or other to turn them on and I can feel them almost vibrating, as if there is power going into them but they are simply not getting moving.

Secondly, is it possible to put on a fresh config for the printer into Klippe? I'm concerned I've messed something up in my attempts to tune.
