Antminer Fan Speed Simulator 4-in-1 | Fan Spoofer + Voltage Stabilization Module
The Antminer Fan Speed Simulator 4-in-1 combines four fan-tach signal sources with voltage stabilization protection in a single plug-and-play module. The board feeds the miner controller a steady PWM tachometer signal on all four fan headers — letting the miner boot and run without triggering fan-error shutdown when the original fans have been removed for water cooling, oil immersion, or silencer-box deployment.
Compatible Antminer models: L7, D7, S17+, T17e, T17+, S17e, T19, S19, S19+, S19a, S19j, S19h, S19 Pro, Z15, and other models using the same 4-fan-header platform. The integrated voltage stabilization circuit smooths the supply rail on the simulator side, preventing brownout transients during miner startup. Gold-plated socket contacts for reliable connection.
When You Need the 4-in-1 Fan Simulator
- Water-cooling / hydro conversion — miner moved to closed-loop cooling; original 4 fans removed.
- Oil immersion deployment — fans removed to prevent oil damage to bearings.
- Silencer box install — external blower replaces internal fans for noise reduction.
- 4 dead fans — temporary fan-error bypass until replacement fans arrive.

FAQ — 4-in-1 Fan Speed Simulator
Q: Will my miner boot normally with the simulator installed?
A: Yes — the simulator generates valid tach signals on all 4 channels, satisfying the controller's fan-monitoring logic. The miner boots and runs without fan-error log entries or protective shutdowns.
Q: Do I still need physical cooling?
A: Absolutely — the simulator only spoofs the fan-tach signal; it does NOT cool anything. You must provide real cooling via water loop, oil bath, silencer box airflow, or replacement fans. Without actual cooling, the miner will trip overtemperature within minutes.
Q: Will it work on the newer T21 / S21 generation?
A: The T21 / S21 family uses a different fan header standard — check the related T21/S21 fan-speed simulator products for those models. The 4-in-1 fits the L7/D7/S17/S19/T19/Z15 family specifically.
Q: Bulk pricing?
A: Yes — email contact@lys-sz.com for volume pricing.
