Stock fans often fail first on long-running ASIC miners — swapping in this original-spec Nidec restores proper thermals and prevents cascading chip failure.\u003c\/p\u003e\n\u003ch3\u003eW12E12BS11B5-07 Fan Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eFeature\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eW12E12BS11B5-07\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eNidec\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize\u003c\/td\u003e\n\u003ctd\u003e120 x 120 x 38 mm (12038)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBearing\u003c\/td\u003e\n\u003ctd\u003eHigh-precision double ball bearing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage\u003c\/td\u003e\n\u003ctd\u003e12 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent\u003c\/td\u003e\n\u003ctd\u003e1.65 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower\u003c\/td\u003e\n\u003ctd\u003e14.8 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRotation Speed\u003c\/td\u003e\n\u003ctd\u003e6000 RPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAirflow\u003c\/td\u003e\n\u003ctd\u003e180.15 CFM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector\u003c\/td\u003e\n\u003ctd\u003e4-pin PWM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Miners\u003c\/td\u003e\n\u003ctd\u003eAntminer S9, S19, S20, S21 series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e380 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003eBrand New\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eWhen to Replace Your Antminer Fan\u003c\/h3\u003e\n\u003cp\u003eTypical fan failure symptoms on Antminer S9 \/ S19 \/ S21 include: rising chip temperatures at constant ambient, increasing fan noise with rumble, miner throttling hashrate below nameplate, or outright fan-stall errors in the control panel logs. Running a miner with a weakened fan will eventually damage hashboard ASICs — far more expensive than a fan swap. The W12E12BS11B5-07 is a drop-in replacement for the stock Antminer fan with matching RPM and static-pressure profile.\u003c\/p\u003e\n\u003ch3\u003eWhy High Static Pressure Matters\u003c\/h3\u003e\n\u003cp\u003eAntminer hashboards are packed with dense heatsink fins. Ordinary case fans move a lot of air in open space but stall against dense finstacks — a high-static-pressure fan like the Nidec W12E12BS11B5-07 maintains airflow through the restriction, keeping silicon junction temperatures in safe range. The double ball bearing is rated for long-duty 24\/7 operation and is the same bearing grade used on Bitmain's original fan orders.\u003c\/p\u003e\n\u003ch3\u003eRelated Antminer Cooling Fans\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/en-th\/products\/w12e12bs11b5-07-antminer-s21-s19k-fan-12cm-4pin-square\"\u003eW12E12BS11B5-07 – Antminer S21 \/ S19K 4-pin Variant\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/en-th\/products\/df1203812b2un-martech-antminer-l7-s19-cooling-fan-12cm-fancooler\"\u003eDF1203812B2UN Martech L7 \/ S19 12cm Fan\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/en-th\/products\/antminer-s19kpro-cooling-fan-12cm-square-4pin\"\u003eAntminer S19K Pro 12cm 4-pin Cooling Fan\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/en-th\/products\/original-martech-7000rpm-cooling-fan-antminer-l9-s19kpro-s21-ks5pro\"\u003eMartech 7000 RPM Cooling Fan – S21 \/ S19K Pro \/ L9\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eKeep your Antminer hashing cool and steady.\u003c\/strong\u003e Order online or \u003ca href=\"mailto:contact@lys-sz.com\"\u003econtact us at contact@lys-sz.com\u003c\/a\u003e for bulk pricing and farm-scale fan replacement programs.
