Specially designed for the Whatsminer M20/M21 series, this plug-and-play fan spoofer ensures your device continues to operate smoothly by simulating the required fan signals. It enables consistent performance and uninterrupted mining even in customized cooling environments like oil immersion, water cooling, or hydro exhaust systems.

Why Choose This Fan Simulator?

This compact and efficient unit bridges the signal gap when fans are removed, allowing the miner or PSU to operate safely without triggering fan error alarms. Built for reliability, it’s an essential tool for professional miners optimizing their rigs for advanced cooling solutions.
