4pin fan speed controller / remover / simulator / spoofer for Whatsminer
The Whatsminer 4pin fan speed emulator is a modification accessory designed specifically for Whatsminer that utilizes a square 4pin fan connector. It is widely used in projects involving the conversion of miners to water cooling, immersion cooling, or noise-reduction setups. By sending a simulated fan speed signal to the miner’s control board, the emulator prevents fan-related error alerts and stops the miner from automatically shutting down when the original fans are removed. It facilitates a quieter operating environment, making it an excellent choice for home-based mining and small-scale mining facility upgrades.
1. Eliminates fan error alerts during cooling modifications
By simulating a valid fan speed signal, it prevents the Whatsminer from triggering fan-failure protection and shutting down after the original fans have been removed for water or immersion cooling upgrades.
2. Plug and play, easy to operate
It adopts a standard square 4-pin interface adapted to the Whatsminer control board, requiring no complicated firmware modification, making installation simple and plug-and-play.
3. Enables quiet mining
An ideal accessory for home mining, allowing for the removal of noisy original fans to create a much quieter mining environment.
4. Compact and lightweight
Features a compact, lightweight design, making it easy to install inside the miner’s chassis.
Suitable for Whatsminer models equipped with a square 4pin fan connector, including the M60S++, M60, M50, M50S, M33S, M32S, M31S, M30S, M20S, and others.
