Active Cooling for Raspberry Pi

Features：

1. High-speed fan with powerful cooling performance

2. Fan speed can be controlled via programmable PWM

3. Open-source control code provided, cooling solution ensures more stable operation, superior performance, and quieter cooling for Raspberry Pi

Control Code Functions：

1. Real-time monitoring of Raspberry Pi’s CPU temperature

2. Fan activates when CPU temperature reaches the set value

3. Multiple temperature threshold settings corresponding to different fan speeds

4. Real-time monitoring of Raspberry Pi’s operating frequency

5. When the Raspberry Pi’s operating frequency reaches the maximum limit, the fan runs at full speed regardless of whether the cooling temperature threshold is reached, for smarter heat management

6. Program is written in Python, making it easy for DIY
