Iceriver Fan Speed Simulator – RX0 KS1 KS2 KS3 KS3M KS3L KS5L Miner Spoofer

Iceriver Fan Speed Simulator | RX0 KS1 KS2 KS3 KS3M KS3L KS5L Fan Spoofer

The Iceriver Fan Speed Simulator is a high-performance 4-in-1 fan spoofer built specifically for Iceriver RX0, KS1, KS2, KS3, KS3M, KS3L, and KS5L miners. When you swap the stock fans for an oil-immersion bath, an air-cooling rebuild, or a silencer box, the miner's firmware still expects to see live fan-tach signals on every channel — without them, the rig throws fan errors and shuts down. This emulator mimics those signals on all four channels at once, keeping the miner happy and your custom cooling solution online.

Designed for crypto mining farms, home miners, and silent-mining enthusiasts, the simulator is a must-have accessory for anyone running custom cooling. It is fully plug-and-play — no firmware changes are required — and works across the entire compatible Iceriver line so a single part covers most of a mixed fleet.

4-in-1 Fan Emulator — Silent Cooling & Miner Protection for Custom Setups

• Compatible with multiple Iceriver models — RX0, KS1, KS2, KS3, KS3M, KS3L, KS5L.
• Prevents miner errors and shutdowns caused by missing fan tach signals after fan removal.
• Supports oil, air, and silent cooling mods — works equally well with liquid immersion baths, repurposed PC fans, or silencer boxes.
• One controller replaces four fans via the 4-in-1 simultaneous simulation function.
• Plug-and-play — no firmware flashing or configuration step required.

Why Iceriver Operators Need a Fan Spoofer

Stock Iceriver firmware monitors fan RPM continuously and triggers a hash-board fault as soon as it loses signal on any channel. This is fine in factory configuration but becomes a problem the moment you re-route airflow through a silencer box, switch to an oil-immersion tank, or reduce noise with quieter aftermarket fans whose tach signal sits outside the expected range. The simulator removes that friction by feeding clean, expected RPM data to the controller — letting the miner run at full hash rate while your cooling stack does its job.
