Need Help With Hot End Fan Control

Hello,
I have two of the same aftermarket fans on my Ender 3 MKS Gen L - https://www.digikey.com/product-detail/en/sunon-fans/MF40202VX-1000U-A99/259-1955-ND/6198973 . One controls the part cooling, the other the hot end cooling. The part fan changes speed through the slicer per usual, but trying to set speed for the hot end fan through Marlin doesn't work. I'd like to set the fan to 80%. I have tried to set lower values i.e 190, 200 etc to no avail. The fan seems to stutter or kind of click repeatedly but does not spin. It only works at full speed.
I know I can use a buck converter or solder in a resistor but I'm trying to avoid that if possible.

define E0_AUTO_FAN_PIN 7 //JL
define E1_AUTO_FAN_PIN -1
define E2_AUTO_FAN_PIN -1
define E3_AUTO_FAN_PIN -1
define E4_AUTO_FAN_PIN -1
define CHAMBER_AUTO_FAN_PIN -1
define EXTRUDER_AUTO_FAN_TEMPERATURE 40 //JL - 50
define EXTRUDER_AUTO_FAN_SPEED 255 // full speed

Here's my :
