Aluminum Case With ICE Tower Cooler For Raspberry Pi 4B


It is aluminum case with ICE tower cooler for Raspberry Pi 4 model B ONLY. It can protect the Raspberry Pi well and dissipate heat well through adjustable-speed fan. We strongly recommend using the official Raspberry Pi operating system, which can directly configure the fan to adjust the speed according to the CPU temperature through the raspi-config command.

Other operating systems may require you to write software yourself and send PWM signals to the fan through GPIO pins to control fan’s speed.


  • Easy to assemble
  • Acrylic Top Cover
  • ICE Tower Cooler
  • Adjustable Speed Fan
  • Precise Positioning
  • Beautiful and Stable
  • For Raspberry Pi 4 model B Only


  • Product Outlook


Package Includes

  • 1 x Aluminum case
  • 1 x Acrylic Top cover
  • 1 x Aluminum bottom cover
  • 1 x ICE Tower cooler
  • 2 x ICE Tower bracket
  • 4 x Copper pillar
  • 2 x M2.5 screws for ICE tower brackets
  • 4 x M2.5 Flat head screw
  • 2 x Thermal Pad
  • 1 x hex wrench
  • 4 x Hexagon socket head screw for Top cover
  • 2 x Rubber anti-slipper pad
  • 1 x Instructions

How to assemble

  • 1. Fix the bracket of ICE Tower Cooler as following figure
  • 2. After peeling off the protect films on Thermal pad, Paste Thermal pad on Raspberry Pi 4B’s CPU and fix the ICE Tower Cooler with copper pillars.
  • 3. Connect fan cable from ice tower cooler to Raspberry Pi on GPIO Pins.
    • Connect the red wire from Fan to 5V Pin on Raspberry Pi 4B’s GPIO Pin
    • Connect the black wire from fan to GND Pin on Raspberry Pi 4B’s GPIO Pin
    • Connect the Blue wire from fan to GPIO14 Pin on Raspberry Pi 4B’s GPIO Pin.
  • 4. Insert Raspberry Pi 4B and ICE Tower Cooler into the case.
  • 5. Peeling off the protect film from Acrylic Top Cover and fix it with hexagon socket screws.
  • 6. Paste the rubber anti-slipper pad on the bottom of the case.

How to configure PWM Fan

We are assume that you are using Raspberry Pi OS (Official).
  • 1. Press Ctrl+ ALT + T or click terminal Icon to open a terminal and typing: “sudo raspi-config”

  • 2. Navigate to 4 Performance Options

  • and navigate to P4 Fan and select YES.

  • Keep 14 as default.

  • select yes, input a temperature in degrees should the fan turn on, Recommend setting to 60 degrees.

  • select yes and reboot your Raspberry Pi.



  • If you are using other OS on Raspberry Pi, please refer to how to generate PWM signal in your OS.

Demo Code

  • Here is a demo code, it will help you to control the fan speed according to the temperature of CPU.
#File Name: fan_control.py

import RPi.GPIO as GPIO
import time
import subprocess

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

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

    while True:
        temp = subprocess.getoutput("vcgencmd measure_temp|sed 's/[^0-9.]//g'")
        if round(float(temp)) >= 45:
            dc = 100
            print("CPU Temp:",float(temp)," Fan duty cycle:",dc)
        if round(float(temp)) >= 40:
            dc = 85
            print("CPU Temp:",float(temp)," Fan duty cycle:",dc)
            dc = 70
            print("CPU Temp:",float(temp)," Fan duty cycle:",dc)

except KeyboardInterrupt:
print("Ctrl + C pressed -- Ending program")
  • Save it and execute it in a terminal:
python3 fan_control.py
