Ultra Bee Dual-Fan Controller Cooling Kit

Just 20W of power can lower controller temperatures by 4–6°C (7.2–10.8°F) with minimal battery consumption. Considering that replacing a controller can cost nearly $700, keeping it cooler is a smart investment.

Powered by Japanese SANYO DENKI San Ace industrial-grade fans, this kit delivers strong airflow to quickly dissipate controller heat. Features a manual on/off switch, a precision-fit mounting bracket for a secure, vibration-resistant installation, and a simple two-screw, plug-and-play setup.
