Ultra Thin Ice Tower Cooler for Raspberry Pi 4B

Description

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.

Features

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

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.setmode(GPIO.BOARD)
GPIO.setup(Fan, GPIO.OUT)

p = GPIO.PWM(Fan, 50)
p.start(0)

try:
    while True:
        temp = sp.getoutput("vcgencmd measure_temp|egrep -o '[0-9]*\.[0-9]*'")
        # print(temp)
        if float(temp) < 48.0:
            p.ChangeDutyCycle(0)
        elif float(temp) > 48.0 and float(temp) < 60.0:
            p.ChangeDutyCycle(100)
            time.sleep(0.1)
        elif float(temp) > 60.0:
            p.ChangeDutyCycle(100)
            time.sleep(0.1)

except KeyboardInterrupt:
    pass
p.stop()
GPIO.cleanup()

• Save it and test it
