Whatsminer 6pin Fan Simulator for Immersion and Oil Cooling Systems
The Whatsminer 6pin fan simulator is a plug-and-play device that replaces the stock cooling fans when running your miner in an immersion or oil cooling setup. Without this simulator, the miner firmware detects missing fans and shuts down. This spoofer sends the correct PWM signal to the control board, allowing the M20, M21 series Whatsminer units to operate normally in liquid-cooled environments without any firmware modification.

Why You Need a Fan Simulator for Immersion Cooling
Whatsminer firmware performs continuous fan speed monitoring. When the miner is submerged in dielectric fluid and the fans are physically removed, the control board registers a fan failure and triggers an automatic shutdown. The 6pin fan simulator solves this by emulating the fan tachometer signal. This is a standard requirement for any professional immersion cooling deployment — without it, your miner simply will not run. The linear 6-pin connector matches the Whatsminer fan header directly, so installation takes seconds.
Choosing the Right Fan Simulator for Your Whatsminer
Whatsminer models use different fan connector types depending on the series. The M20 and M21 series use the 6-pin linear connector covered by this product, while some M30 and newer models use a 4-pin ATX connector instead. Always verify which connector your specific model requires before ordering. For large-scale immersion deployments, contact us for volume pricing.
