I have Removed Kali linux from USB and Installed Raspberry Pi official but fan stops after boot.
it's an active cooler
below 50°C, the fan does not spin at all (0% speed)

at 50°C, the fan turns on at a low speed (30% speed)

at 60°C, the fan speed increases to a medium speed (50% speed)

at 67.5°C, the fan speed increases to a high speed (70% speed)

at 75°C the fan increases to full speed (100% speed)
testing:
fan run at full speed

Code:

pinctrl FAN_PWM op dl
back to auto

Code:

pinctrl FAN_PWM op a0
stress

Code:

yes >/dev/null & yes >/dev/null & yes >/dev/null & yes >/dev/null & 
end test

Code:

pkill yes
