4028 fan setup MantaM8P 1.1

Hello,
I have been trying for a few hours to get my pwm fan to work.
I can get it to spin at 100% power all the time, or not at all.
Here is my current config for the fan which doesnt work at all.
[fan]
pin:PC14
#tachometer_pin:^PC14
enable_pin:!4p_fan_part_cooling_pin
#tachometer_ppr: 2
#off_below: 0.0
cycle_time: 0.01
#tachometer_poll_interval: 0.0015
#shutdown_speed: 0.0
#kick_start_time: 2.0

Im trying to use the Fan4 and Fan5 headers on the board as I assume I will need one for the pwm and the other to supply power.
If anyone has any idea how I need to wire this and set the config I would greatly appreciate it.
