About the Product
Whatsminer Power Supply Fan Simulator for Immersion Cooling
Optimize your Whatsminer PSU with this high-quality Fan Simulator, designed for models P10, P11, P20, P21, P21D, P21E, P21B, P221B, P221C, P222B, and P222C. Specifically engineered for Whatsminer official power supplies, this simulator replaces the stock fan and allows seamless use with hydro, oil, and air blower turbine cooling systems.

Efficient Speed Controller for Noise Reduction & Longer Lifespan
By simulating fan operation, this plug-and-play controller reduces operating noise, extends power supply life, and ensures stable mining performance. It delivers precise fan speed control to maintain efficient cooling in immersion setups without triggering fan errors.
