My How-To on building a fully automatic, stand-alone ESPHome / D1 Mini based 5-24V PWM PC Fan Controller - Ideal for keeping any equipment cabinet or WLED controller cases cool.
Using a DALLAS temperature sensor it'll control the fan speed, from 0 to 100% automatically - based on a threshold temperature you set in Home Assistant.
This project also features an ALARM Function that will alert you if the fan has been running at MAX speed for longer than 10 seconds!
