Aluminum Brick Case

Zp-0138-7.jpg

Descriptions

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. 

Features

  • Easy to assemble
  • Acrylic Top Cover
  • Ultra-Quiet Cooling Fan
  • Adjustable Speed (PWM)
  • Precise Positioning
  • Beautiful and Stable
  • Support Raspberry Pi 4 model B Only

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”

  • and navigate to P4 Fan and select YES.
0138Step3.png


  • Keep 14 as default.
0138Step4.png


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

  • 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
#!/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:
python3 fan_control.py
