iBeLink 4-in-1 Fan Speed Simulator | Plug-and-Play Tach Spoofer for BM-N1Max, BM-K1Max, BM-S1Max, BM-S3 & BM-K1 Miners
The iBeLink 4-in-1 Fan Speed Simulator is a plug-and-play tach-signal spoofer for the iBeLink BM-N1Max, BM-K1Max, BM-S1Max, BM-S3, and BM-K1 ASIC miners. Replaces all four original chassis fans with a single connector that returns valid RPM feedback to the control board — so the miner runs normally with no fan-failure errors, no automatic shutdowns, and no firmware lockouts.
Designed for the two workflows where the original fans are removed or replaced: silencer enclosure deployments (large external ducted fan moves the air, original chassis fans removed for noise) and immersion / oil-cooling installs (heat extracted by the dielectric loop, chassis fans not needed). In both cases the firmware still expects four valid tach readings — the 4-in-1 simulator supplies them on a single plug.

FAQ — iBeLink 4-in-1 Fan Simulator
Q: Does the miner still need cooling without the chassis fans?
A: Yes — absolutely. The fan simulator only spoofs tach feedback to keep the firmware happy. Heat still has to leave the hashboards somehow. Use this with a silencer's external fan, or with proper immersion / oil cooling. Running with no airflow path will overheat the boards in minutes.
Q: Why one simulator instead of four single-channel spoofers?
A: Cleaner install, fewer connection points to fail, and lower cost per channel. A single 4-in-1 device matches the firmware's expectation of four valid tach signals with one plug — same end result as four separate spoofers, no risk of one channel disconnecting and triggering a fan-failure shutdown.
Q: Will the firmware detect the spoofer?
A: The simulator returns valid RPM-pattern signals that match what a healthy fan would produce. The firmware sees four working fans and runs normally. No firmware modification or unlock required.
Q: Bulk pricing for fleet immersion / silencer deployments?
A: Yes — email contact@lys-sz.com for volume pricing on iBeLink simulator multi-unit orders.
