Ultra Thin Ice Tower Cooler for Raspberry Pi 4B

Ultrathin ice tower01.jpg


This is an ultra-thin ice tower cooler that only supports Raspberry Pi 4B. It includes ultra-thin fans and supports fan speed regulation. The speed can be controlled by programming the GPIO pins of the Raspberry Pi, and the heat sink is ultra-thin.


  • Ultra Thin
  • Support fan speed regultion
  • Support Raspberry Pi 4B ONLY
  • Good Heat dissipation effect


 NOTE: Raspberry Pi 4B is not included in the package, need additional purchase.

How to assemble

  • 1. Fix the bracket to ICE tower cooler with M2.5 screws.
  • 2. Peel off the protect film of thermal pad and paste it on top of CPU and Memory chip.
  • 3. Fix the copper pillar to the bracket.
  • 4. Fix ICE tower cooler to Raspberry Pi 4B with M2.5 nuts.
  • 5. Connect Red wire to Raspberry Pi's GPIO on 5V
  • 6. Connect Black wire to Raspberry Pi's GPIO on GND
  • 7. Connect Blue wire to Raspberry Pi's GPIO on TXD

Package Includes

  • 1 x Ultra Thin ICE Tower Cooler
  • 4 x Screws
  • 1 x Screw driver
  • 4 x Thermal Pad

How to control fan speed

  • Default OS: Raspberry Pi OS
  • GPIO 14 is connected to fan pwm controller pin, you can just testing by using this code and modify it as you well.
  • Create a file named fan_control.py
  • Copy and paste following code
import RPi.GPIO as GPIO
import time
import subprocess as sp

# initializing GPIO, setting mode to BOARD.
# Default pin of fan is physical pin 8, GPIO14
Fan = 8
GPIO.setup(Fan, GPIO.OUT)

p = GPIO.PWM(Fan, 50)

    while True:
        temp = sp.getoutput("vcgencmd measure_temp|egrep -o '[0-9]*\.[0-9]*'")
        # print(temp)
        if float(temp) < 48.0:
        elif float(temp) > 48.0 and float(temp) < 60.0:
        elif float(temp) > 60.0:

except KeyboardInterrupt:
  • Save it and test it
