The Smart Cooling HAT keeps your Raspberry Pi running cool with an intelligent fan that automatically adjusts speed based on CPU temperature. In testing, it reduces board temperature by approximately 15°C, extending the lifespan and stability of your Pi. The HAT features a 40-pin pass-through header so you can still access all GPIO pins, plus an optional OLED display mounting position for real-time system monitoring. Three programmable RGB LEDs add visual flair with effects like breathing, rainbow, and waterfall patterns.
