Description

This is a thin and lightweight heat sink, equipped with a 3510 ultra-quiet cooling fan, and the fan supports PWM speed regulation, which is perfectly compatible with Raspberry Pi OS. Other systems need to manually write python or C code to drive the fan speed through PWM.
NOTE: Supports Raspberry Pi 4B Only, Automatic speed control function only supports Raspberry Pi OS.

Features

  • Lightweight and silent
  • Support PWM control speed regulation
  • Compatible with official system configuration
  • Easy to install and fix
  • Good heat dissipation effect

How to enable auto adjustable fan

  • Turn on Raspberry Pi and login.
  • Open a terminal and typing:
sudo raspi-config
  • Navigate to 4 Performance Options -> P4 Fan and select YES-> Input or keep it as 14->OK->input temperature in degrees should the fan turn on, for example: I'd like turn on the fan when the temperature reached to 65 degrees, input 65 and press Enter.

How to enable it via Programming

  • Make sure RPi.GPIO library has been installed.
  pip freeze |grep RPi.GPIO 

If feedback is:

RPi.GPIO==0.7.0

means library is OK.

  • Open a terminal and create a file named: pwm-fan-control.py
  • Copy and paste following code into the file and save it.
import RPi.GPIO as GPIO
import time
import subprocess

GPIO.setmode(GPIO.BCM)
GPIO.setup(14, GPIO.OUT)
pwm = GPIO.PWM(14,100)

print("\nPress Ctrl+C to quit \n")
dc = 0
pwm.start(dc)

try:
    while True:
        temp = subprocess.getoutput("vcgencmd measure_temp|sed 's/[^0-9.]//g'")
        if round(float(temp)) >= 65:
            dc = 100
            pwm.ChangeDutyCycle(dc)
            time.sleep(0.05)
        else:
            dc = 0
            pwm.ChangeDutyCycle(dc)
            time.sleep(0.05)
except KeyboardInterrupt:
    pwm.stop()
    GPIO.cleanup()
    print("Ctrl + C pressed -- Ending program")
  • Execute it by typing:
python3 pwm-fan-control.py 
  • The fan will be turned on when the CPU temperature is reached to 65 degrees.
