==Aluminum Brick Case ==

==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.

<pre>NOTE: Raspberry Pi 4B is not included in the package, require additional purchase. </pre>

==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 configure PWM Fan==
<pre>We are assume that you are using Raspberry Pi OS (Official).</pre>
* 1. Press Ctrl+ ALT + T or click terminal Icon to open a terminal and typing: “sudo raspi-config”
[[File:0138Step1.png|left|800px]]
 
* 2. Navigate to '''4 Performance Options'''
[[File:0138Step2.png|left|800px]]
 
* and navigate to '''P4 Fan''' and select YES.
[[File:0138Step3.png|left|800px]]
 
* Keep '''14''' as default.
[[File:0138Step4.png|left|800px]]
 
* select yes, input a temperature in degrees should the fan turn on, Recommend setting to '''60''' degrees.
[[File:0138Step5.png|left|800px]]
 
* 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.

===Demo Code===
* Here is a demo code, it will help you to control the fan speed according to the temperature of CPU.
