Any part cooling fan always on 100%

I just went through a huge mess with having to reinstall everything and now my initial issue is still going on.

My 4028 fan turns on full blast when the printer boots up. I got the PWM wire properly connected as far as I can see, I got the fan pin in right. I can't get it to go at anything below full blast even when it's set to 0% on mainsail.

I followed the setup in the docs, found out the pin in the docs is an always on and shouldn't be used so put it in PD15. No jumper between the PWM pins. So don't know why it's not working.

Never had this issue with the 7530 fan I had before and it was just a 2 pin.
