This \u003cstrong\u003e2-wire fan speed simulator\u003c\/strong\u003e generates the RPM signal the PSU expects, allowing it to operate \u003cstrong\u003ewithout a physical fan\u003c\/strong\u003e.

Whether you are converting a single home miner to silent operation or deploying hundreds of units into an immersion tank, one simulator SKU handles all models.\u003c\/p\u003e\n\u003ch3\u003eWhen and Why to Use a PSU Fan Simulator\u003c\/h3\u003e\n\u003cp\u003eThe PSU firmware monitors fan tachometer feedback. If the signal disappears (fan unplugged or dead), the PSU shuts down to protect itself from overheating. The simulator provides a continuous tach signal regardless of whether a fan is spinning, so the PSU stays powered on. Use this device when you route PSU exhaust through a silencer duct with its own fans, when the entire miner operates submerged in dielectric fluid, or when you replace the stock PSU fan with a quieter aftermarket blower wired separately.\u003c\/p\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eDisconnect the PSU from mains. Unplug the original 2-wire fan connector from the PSU fan header. Plug the simulator's connector into the same header. If you are keeping external airflow (silencer duct or aftermarket fan), wire that fan to its own 12 V source. Reconnect mains and verify the PSU powers on without error. The simulator draws negligible current — under 10 mA.\u003c\/p\u003e\n\u003ch4\u003ePSU Fan Simulator – Compatibility\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding: 6px 12px;\"\u003eParameter\u003c\/th\u003e\n\u003cth style=\"text-align: left; padding: 6px 12px;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eType\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e2-wire fan speed emulator\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCompatible PSUs\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eAPW3++, APW7, APW8, APW9, APW12, APW17\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCompatible Miners\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eS17e–S19XP, L7, K7, D7, KS3, KA3, E9, HS3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eFunction\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eNoise reduction \/ immersion compatibility\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCondition\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eRelated PSU Fan Simulators \u0026amp; Cooling Accessories\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/iceriver-psu-fan-speed-simulator-bph3640-power-supply-cooling-replacement\"\u003eIceriver PSU Fan Simulator – BP-H-3640\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/avalon-psu-2-in-1-power-supply-fan-simulator-immersion-cooling-avalonminer-asic\"\u003eAvalon PSU 2-in-1 Fan Simulator – Immersion\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/ipollo-psu-fan-simulator-immersion-cooling-power-supply-performance\"\u003eiPollo PSU Fan Simulator – Immersion Cooling\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/avalon-psu-power-supply-fan-simulator-enhanced-cooling-noise-reduction\"\u003eAvalon PSU Fan Simulator – Noise Reduction\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eConverting miners to silent or immersion operation at scale? \u003ca href=\"mailto:contact@lys-sz.com\"\u003eContact us at contact@lys-sz.com\u003c\/a\u003e for volume pricing on simulators.\u003c\/p\u003e\n\u003cp\u003eWorldwide shipping from our Shenzhen warehouse.\u003c\/p\u003e","brand":"LYS Shenzhen","offers":[{"title":"Default Title","offer_id":43504272736435,"sku":null,"price":2.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/6710\/4179\/files\/antminer-bitmain-apw12-fan-speed-simulator-immersion-hydro-silent-oil-cooling-power-supply.webp?v=1744553910","url":"https:\/\/lys-sz.com\/products\/antminer-apw12-bitmain-psu-fan-speed-simulator","provider":"LYS Shenzhen","version":"1.0","type":"link"}
