Iceriver AL3 KS5M Fan Speed Simulator | 4-in-1 Spoofer for Water Oil Cooling & Silencer Mods
The Iceriver AL3 KS5M Fan Speed Simulator is a high-performance 4-in-1 fan spoofer built specifically for the Iceriver AL3 and KS5M miners. When you upgrade your stock cooling to a water-cooling loop, oil-immersion bath, or silencer box, the firmware still expects to see live fan-tach signals on every channel — without them, the rig throws fan errors and stops hashing. This emulator feeds clean simulated RPM signals across all four channels at once, keeping the AL3 or KS5M operating uninterrupted while your custom cooling solution does its job.
The standard 4-pin Square 5557 connector drops in cleanly where the original fan harness used to live, so installation is a one-step plug-and-play operation with no firmware changes required. Ideal for ASIC operators who pursue cooling-system upgrades without compromising hash-rate stability.
4-in-1 Cooling Fan Spoofer — Perfect for AL3 & KS5M Modifications
- 4-in-1 functionality — controls all four fan channels with a single device.
- Plug-and-play installation — uses a standard 4-pin Square 5557 connector for direct fitment.
- Optimised for cooling mods — ideal for air-to-liquid conversions, silent mining setups, and oil-cooled rigs.
- Prevents miner errors — emulates realistic RPM signals to avoid shutdowns triggered by missing tach data.
- Compact and reliable — designed for continuous duty in production mining environments.
Why AL3 and KS5M Operators Need a Fan Spoofer
Stock Iceriver firmware monitors fan RPM continuously. The moment the controller stops seeing tach pulses on a channel, it raises a fan-fault flag and halts hashing — protective behaviour in factory configuration, but a problem the moment you re-route airflow through a silencer box, oil tank, or aftermarket fan stack with non-standard tach signals. The simulator removes that friction: feed the controller the signals it expects, and the miner runs at full hash rate while your custom cooling stack carries the thermal load.
