A generic 140mm PC fan will mount mechanically but won't meet the static-pressure requirement at the operating point — the result is hashboard chip junction temps that drift up by 5-10°C, hash-rate drop, and intermittent fan-error fault codes. The GH14038BZW-1 matches the original airflow \/ pressure curve and the controller sees a normal RPM tach.\u003c\/p\u003e\n\u003ch3\u003eReplacement Procedure\u003c\/h3\u003e\n\u003cp\u003ePower down the miner and disconnect mains. Remove the chassis fan grille screws and lift out the failed fan. Note the original connector (4-pin or 6-pin) and order the matching variant. Plug the new GH14038BZW-1 into the controller header — the airflow arrow should point in the same direction as the original (intake or exhaust depending on the slot). Power on and verify the controller dashboard reports normal RPM and that all hashboards stay within their target temperature range.\u003c\/p\u003e\n\u003ch4\u003eGH14038BZW-1 Fan Specifications\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;\"\u003eModel\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eGH14038BZW-1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eDimensions\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e140×140×38mm (14038)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eVoltage\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e12VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCurrent\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e4.5A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eConnector\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e4-pin or 6-pin (specify on order)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eBearing\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eDual ball bearing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCompatibility\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eWhatsminer M20 \/ M21 \/ M30 \/ M31 \/ M32 \/ M50 \/ M53 \/ M56 \/ M60 series \u0026amp; selected Avalon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eOperating Temp\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e-10°C to +70°C\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 Whatsminer 140mm Fans\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kz14038b012u-ball-bearing-cooling-4pin-fan-14cm-whatsminer-m30-m31-m32\"\u003eKZ14038B012U 4-pin – Whatsminer M30\/M31\/M32\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kz14038b012u-ball-bearing-cooling-fan-14cm-whatsminer-m20-m21-6pin-6p\"\u003eKZ14038B012U 6-pin – Whatsminer M20\/M21\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/pfc1412he00-14cm-high-speed-cooling-fan-8000rpm-whatsminer-avalon\"\u003eDelta PFC1412HE-00 140mm 12V 9A – Whatsminer \/ Avalon\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/whatsminer-4pin-fan-simulator-immersion-cooling-p21-p221-p222\"\u003eWhatsminer 4-pin Fan Simulator – Immersion Cooling\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eStocking GH14038BZW-1 fans for a Whatsminer service line? \u003ca href=\"mailto:contact@lys-sz.com\"\u003eContact us at contact@lys-sz.com\u003c\/a\u003e for case-quantity pricing. Worldwide shipping from our Shenzhen warehouse.\u003c\/p\u003e","brand":"LYS Shenzhen","offers":[{"title":"4 pin square","offer_id":41718900719795,"sku":null,"price":9.5,"currency_code":"USD","in_stock":true},{"title":"6 pin linear","offer_id":41718900752563,"sku":null,"price":9.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/6710\/4179\/files\/GH14038BZW-1-12V-14cm-140x38mm-14cm-High-Speed-Cooling-Fan-Fast-RPM-Whatsminer-Avalon_4.webp?v=1747885371","url":"https:\/\/lys-sz.com\/products\/gh14038bzw-14cm-cooling-fan-8000rpm-whatsminer-avalon","provider":"LYS Shenzhen","version":"1.0","type":"link"}
