Aluminum Brick Case
It is aluminum Brick Case which is supporting 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.
NOTE: Raspberry Pi 4B is not included in the package, require additional purchase.

How to assemble
- 1. Fix 3510 Ultra-quiet Cooling Fan as following figure
- 2. Conect fan cable to GPIO Pin:
** 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
- 3. Insert Raspberry Pi 4B and 3510 Ultra-Quiet Cooling Fan into the case, and fix it with M2.5 Flat head screws.
- 4. Fix the aluminum bottom cover to case with M2.5 flat head screws.
- 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.
- 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 #!/usr/bin/python3 import RPi.GPIO as GPIO import time import subprocess GPIO.setmode(GPIO.BCM) GPIO.setwarnings(False) 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'") if round(float(temp)) >= 45: dc = 100 pwm.ChangeDutyCycle(dc) print("CPU Temp:",float(temp)," Fan duty cycle:",dc) time.sleep(180.0) if round(float(temp)) >= 40: dc = 85 pwm.ChangeDutyCycle(dc) print("CPU Temp:",float(temp)," Fan duty cycle:",dc) time.sleep(120.0) else: dc = 70 pwm.ChangeDutyCycle(dc) print("CPU Temp:",float(temp)," Fan duty cycle:",dc) time.sleep(60.00) except KeyboardInterrupt: pwm.stop() GPIO.cleanup() print("Ctrl + C pressed -- Ending program")
- Save it and execute it in a terminal:
