Introduction

Overview

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
  • 4010 speed-adjustable Fan with PWM

The PWM pin can be connected to TXD(GPIO14)/GPIO12/GPIO18.
When used with FAN Adapter, the default PWM pin is D12(GPIO12) ,You can switch to TXD or D18 by modifying the 0R resistor.


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(GPIO14)/D12(GPIO12)/D18(GPIO18) or connect to FAN Adapter (default pwm pin is D12(GPIO12))

How to control fan speed

  • Controled by Raspberry Pi OS:
We assume you have a Raspberry Pi OS installed.

1.Connect the pins of the cooling fan to the Raspberry Pi or FAN Adapter.Make sure you have already connected the Red wire to 5V, Black wire to GND pin, and Blue Wire to PWM (can be connected to TXD(GPIO14)/GPIO 12/GPIO18).

2. Turn on Raspberry Pi and login, open a terminal and enable Fan control as following Steps: Typing following command in terminal:sudo raspi-config
3. Navigate to Performance options
4. Navigate to Fan
5. Select yes
6. Input 12 means using GPIO12 as PWM output Pin.

If you connect to TXD(GPIO14),pls using GPIO14 as PWM output Pin

7. Change threashold trigger temperature to 60 degrees.
8. Confirm it.
9. Navigate to Finish and reboot Raspberry Pi as it required to take effect.


In this case, the fan will be triggered to rotate only when the CPU temperature of the Raspberry Pi reaches 60 degrees, otherwise the fan will not spin.

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.py
  • Copy and paste following code into the file and save it.

Demo1

import RPi.GPIO as GPIO
import time
import subprocess

GPIO.setmode(GPIO.BCM)
##Set to false, other processes occupying the pin will be ignored
GPIO.setwarnings(False)
GPIO.setup(12, GPIO.OUT)
pwm = GPIO.PWM(12,100)

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

def ReadTemp():
        # view CPU temperature 
        file = open("/sys/class/thermal/thermal_zone0/temp")
        cpu = float(file.read()) / 1000
        file.close()
        print('CPU temperature is: %2.2f' % cpu)
        time.sleep(5)

try:
    while True:
        temp = subprocess.getoutput("vcgencmd measure_temp|sed 's/[^0-9.]//g'")
        ReadTemp()
        if round(float(temp)) >= 40:
            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")

Demo2

import RPi.GPIO as GPIO
import time
import subprocess as sp


# initializing GPIO, setting mode to BOARD.
# Default pin of FAN Adapter is physical pin 32, GPIO12; 
Fan = 32  #if you connect to pin txd physical pin 8, GPIO14,then set to :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()

Run Demo code

  • Execute it by typing:
python3 pwm-fan.py
  • The fan will be turned on when the CPU temperature is reached to 65 degrees.
The PWM control pin in the code needs to be changed according to the GPIO pin actually connected.
  • If you connect TXD (GPIO14), the corresponding number in the code needs to be changed to 14;
GPIO.setup(14, GPIO.OUT)
pwm = GPIO.PWM(14,100)

if it is connected to FAN Adapter, the default is to connect D12 (GPIO12), run the code as follows:

GPIO.setup(12, GPIO.OUT)
pwm = GPIO.PWM(12,100)
