Red Devil 4-Pin Fan Simulator – Mini Version (Plug & Play)
The Red Devil Mini 4-Pin Fan Simulator is designed for users running miners in oil immersion cooling systems. It’s compatible with popular mining machines like Antminer, Innosilicon, and Ebit, as long as they use a standard 4-pin fan connector.

This independent core speed simulator solves the common issue of miners failing to start due to missing or unrecognized fans. It replicates actual fan speed signals and sends them to the miner’s control board, ensuring smooth operation without needing a physical fan.

This Mini Version is compact, reliable, and fully plug-and-play — a perfect solution for advanced cooling setups.
