Control the PWM of your laptop cooling pad fan using ESP32 via USB, based on your Windows CPU/GPU temperatures, taken from AIDA64.

How it works

• Gets temperatures from AIDA64
• Filters them by CPU and GPU sensors
• Takes the maximum int value among all temperatures
• Sends PWM command (Dimmer {value} by default) to the serial device

AIDA64 Preparation

Getting CPU Temperature appeared to be harder on my Windows 11 i9-13900HX than flashing and connecting ESP32! The only working way I found was AIDA64 via WMI. If you can get your CPU Temperature easier - good for you!

• Run AIDA64
• In AIDA64 Preferences->External Applications->Enable writing sensors to WMI
• In AIDA64 Preferences->External Applications0>Enable Temperature sensors
• Keep AIDA64 open

Serial Device Preparation

Example: ESP32_Tasmota

• Connect your Serial Device via USB
• Attach a device pin to the fan PWM
• Attach the device Ground pin to the fan Ground

Script Preparation

• Create .env and fill it using .env.example

Script Execution

GUI

• Use pre-built binaries or run build.cmd

Console

• Run run.cmd or python -m source
