hey, i recently bought the pironman5 case and everything works fine except the pwm ice cube tower cooler. i tried many things, i check the conections and everything is fine (it turns on when i turn my pi on) but it stops and never turns on again. i did a few stress tests and it reached 62 degrees celsious and it didnt turn on. i also reinstaled the os on the sd card (oficial raspi sd card) and updated the system. The fan doesnt turn on. what should i do?
Hi, had the same issue.
Step1:
sudo pinctrl FAN_PWM a0
Step 2: I put these lines in the /boot/firmware/config.txt
#Fan PWM
dtparam=cooling_fan=on
dtparam=fan_temp0=50000
dtparam=fan_temp0_hyst=5000
dtparam=fan_temp0_speed=75
dtparam=fan_temp1=60000
dtparam=fan_temp1_hyst=5000
dtparam=fan_temp1_speed=125
dtparam=fan_temp2=67500
dtparam=fan_temp2_hyst=5000
dtparam=fan_temp2_speed=175
dtparam=fan_temp3=75000
dtparam=fan_temp3_hyst=5000
dtparam=fan_temp3_speed=250
Step 3:
reboot

Please also check whether the pins of the Pi 5’s fan interface are properly aligned and connected to the heatsink connector.
Some users have encountered bent pins on the Pi 5’s fan interface due to misalignment with the heatsink connector, which prevented the connection from being established. Without a proper connection to the heatsink connector, the cooling fan will definitely not work.
Please refer to the attached image for clarification.
