The 52Pi New Colorful Ice Tower Cooler is inspired by the single-stack tower-style heatsink and fan (HSF) assemblies which dominate the desktop PC market. It includes thermal interface material (TIM) pads, mounting brackets and accessories for the Raspberry Pi 4 and Raspberry Pi 3 Model B/Model B+, a tiny screwdriver, and a small but full-color manual. new feature is using Compatible bracket and a color LED fan with automatic color change.
- Color LED fan with automatic color change
- Single-stack tower-style heatsink
- DC 5V Power in (Can be powered by the Raspberry Pi)
- 5mm copper tube
- Super heat dissipation
- Rated power 0.4W @5V, 0.08A
- Easy to setup
- Acrylic protection panel
- Plug and play
Adjustable Speed Fan (Upgrade version)
This is a fan that supports PWM pulse width modulation signal to control the speed, suitable for various DIY environments, you can program the blue pin and control the fan speed through the PWM signal. If you connect it to your Raspberry Pi, the latest Raspberry Pi OS will support Fan speed control via CPU temperature function, and you need to enable it by using raspi-config tool.
- Upgrade to 3 wire control, Red wire connect to 5V, Black wire connect to GND, Blue wire connect to GPIO(which support PWM signal output)
- Support PWM signal control fan speed.(Need programming)
How to connect it to RPi
How to assemble
Raspberry Pi 4B
- 1. Fixed the steel mounting fixer to radiator's heat dissipation cube with M2.0 screws
- 2. Fixed the steel mounting fixer to Raspberry Pi 4B’s mounting hole with M2.5 copper stick, and please make sure the heat dissipation is contact to CPU shield properly.
- 3. Fixed the copper stick to Raspberry Pi with M2.5 nuts.
- 4. Connect the red wire to GPIO 5V pin and black wire to GPIO GND pin.
How to control fan speed
- Controled by Raspberry Pi OS:
We assume you have a Raspberry Pi OS installed.
1.Make sure you have already connected the Red wire to 5V, Black wire to GND pin, and Blue Wire to GPIO 14 (TXD).
2. Turn on Raspberry Pi and login, open a terminal and enable Fan control as following Steps: Typing following command in terminal:
3. Navigate to "Performance options"
4. Navigate to "Fan"
5. Select "yes"
6. Input "14" means using GPIO 14 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.
NOTE: 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:
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'") print("Current CPU Temperature is: %f degree", temp) 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")
- Execute it by typing:
- The fan will be turned on when the CPU temperature is reached to 40 degrees.
