A dedicated test fixture connects directly to the hashboard outside the miner chassis and scans every chip position individually, flagging any that do not respond, return incorrect data, or show abnormal voltage domains. This level of precision turns a multi-hour guesswork process into a 10-minute diagnosis.\u003c\/p\u003e\n\u003ch3\u003eHow to Use the Fixture\u003c\/h3\u003e\n\u003cp\u003eConnect the hashboard to the test fixture using the appropriate signal cable. Power the fixture and launch the scanning software — it will enumerate every chip on the board and display a pass\/fail map. Failed positions are typically highlighted in red, with the specific chip location (row and column) shown so you can match it to the physical board layout. Once identified, remove and replace the faulty chip using the corresponding KF-series tin tool and a hot-air station, then re-scan to confirm the repair was successful.\u003c\/p\u003e\n\u003cp\u003eThe fixture is compatible across the M20 through M31 family because these generations share the same signal protocol.

After powering on, confirm that the 12 V output reads within ±5 % on both rails using a multimeter or the miner's built-in voltage reporting. If you experience intermittent reboots, check the 20 A glass fuse on the input stage and inspect the output cable for damage before replacing the entire unit.\u003c\/p\u003e\n\u003ch4\u003eP21 PSU Technical Specifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eP21\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCategory\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSwitching Power Supply\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInput\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e200-277VAC 50\/60Hz 20A Max\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOutput 1\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e12V – 285A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOutput 2\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e12V – 12A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOutput Power\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3300W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCondition\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePlug Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eC19\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible Devices\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eWhatsminer M10, M20, M20S, M21, M21S\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eRelated Replacement Parts\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/20a-250v-glass-fuse-whatsminer-p21-psu-repair\"\u003e20A 250V Glass Fuse – Whatsminer P21 PSU Repair\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/bcx53-al-pnp-silicon-af-transistor-whatsminer-psu-p21\"\u003eBCX53 PNP Transistor – Whatsminer PSU P21\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/18p-data-cable-whatsminer-m21b-psu-power-supply-connection\"\u003e18P Data Cable – Whatsminer M21B PSU Connection\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/advanced-hr1001a-mps1745-llc-controller-whatsminer-power-supply-repair\"\u003eHR1001A LLC Controller – Whatsminer Power Supply Repair\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNeed a quote for multiple units or have questions about compatibility with your mining setup? \u003ca href=\"mailto:contact@lys-sz.com\"\u003eContact us at contact@lys-sz.com\u003c\/a\u003e — our team of mining hardware engineers is ready to help.\u003c\/p\u003e\n\u003cp\u003eWorldwide shipping from our Shenzhen warehouse.\u003c\/p\u003e","brand":"LYS Shenzhen","offers":[{"title":"Default Title","offer_id":41715946094771,"sku":null,"price":112.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/6710\/4179\/files\/P21-whatsminer-Switching-Power-Supply-PSU-3300W-C19-plug-m20-m21-crypto-miner_2.webp?v=1747103508"},{"product_id":"whatsminer-p21d-switching-power-supply-psu-3300w","title":"Whatsminer P21D Switching Power Supply PSU 3300W","description":"\u003ch2\u003eWhatsminer P21D Switching Power Supply 3300W – Replacement PSU for M20S, M21S, M30S \u0026amp; M31S\u003c\/h2\u003e\n\u003cp\u003eThe \u003cstrong\u003eWhatsminer P21D\u003c\/strong\u003e is a \u003cstrong\u003e3,300 W switching power supply\u003c\/strong\u003e for the \u003cstrong\u003eM20S (62–70 T), M21S (50–58 T), M30S and M31S\u003c\/strong\u003e.

Verify in the dashboard that all hashboards are detected and hash rate reaches target. The P21D's 34 dB noise level makes it one of the quieter options in the P21 family.

A failed NCP1399AC causes the PSU to produce no output or oscillate erratically, often with audible transformer buzz. The operating temperature range of \u003cstrong\u003e-40°C to 125°C\u003c\/strong\u003e provides ample margin, but cumulative stress over months of continuous operation eventually takes its toll.\u003c\/p\u003e\n\u003ch3\u003eReplacement Procedure\u003c\/h3\u003e\n\u003cp\u003eDisconnect mains and discharge all capacitors.

A failing fan causes the PSU internal temperature to climb, accelerating electrolytic capacitor degradation and eventually triggering thermal shutdown or permanent damage. Replacing a worn fan with the PFR0612DHE costs a fraction of a full PSU replacement and can extend the life of the power supply by months or years. For mining farms running multiple Whatsminer units, keeping spare PSU fans in stock is a basic preventive maintenance practice.\u003c\/p\u003e\n\u003ch3\u003eSelecting the Right PSU Fan for Your Mining Power Supply\u003c\/h3\u003e\n\u003cp\u003eMining power supplies use various fan sizes depending on the manufacturer and model. Whatsminer PSUs typically use either 60mm or 80mm fans. Always check the physical dimensions and connector type of your original fan before ordering a replacement. If you need a different size, we stock a full range of PSU cooling fans for Whatsminer, Bitmain, and Avalon power supplies.\u003c\/p\u003e\n\u003ch3\u003eRelated PSU Cooling Fans for Mining Power Supplies\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/da08025b12ug-power-supply-cooling-fan-8cm-microbt-whatsminer-p21-psu-cooler\"\u003eDA08025B12UG 80mm PSU Fan for Whatsminer P21\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/ffb0412vhn-4cm-4028-cooling-fan-power-supply-unit-psu-apw9-apw8\"\u003eFFB0412VHN 40mm Fan for Bitmain APW9 PSU\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/psad16025bm-12vdc-6025-6cm-cooling-fan-crypto-miner-psu-power-supply-bitmain-apw3-apw7\"\u003ePSAD16025BM 60mm Fan for Bitmain APW3 APW7 PSU\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/afc0612d-6025-delta-cooling-fan-power-supply-unit-psu-bitmain-apw3-apw7\"\u003eAFC0612D 60mm Delta Fan for Bitmain PSU\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eKeep your Whatsminer PSU running cool.\u003c\/strong\u003e Order this replacement fan now or \u003ca href=\"mailto:contact@lys-sz.com\"\u003econtact us at contact@lys-sz.com\u003c\/a\u003e for bulk orders.

You should see a clean 24MHz sinusoid or square wave. No output or distorted output (low amplitude, jitter, drift) indicates failed crystal. Note that scope probing the crystal pads can sometimes pull the oscillator off-frequency — use a high-impedance probe.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can the same crystal work on M20S or M30S hashboards?\u003c\/strong\u003e\u003cbr\u003eA: The 12-54MHz family covers multiple Whatsminer hashboards but the specific frequency varies by model.

When the miner is submerged in dielectric fluid and the fans are physically removed, the control board registers a fan failure and triggers an automatic shutdown. The 6pin fan simulator solves this by emulating the fan tachometer signal. This is a standard requirement for any professional immersion cooling deployment — without it, your miner simply will not run. The linear 6-pin connector matches the Whatsminer fan header directly, so installation takes seconds.\u003c\/p\u003e\n\u003ch3\u003eChoosing the Right Fan Simulator for Your Whatsminer\u003c\/h3\u003e\n\u003cp\u003eWhatsminer models use different fan connector types depending on the series.

The simulator removes the fan entirely; the PSU gets its cooling from the coolant it sits in, and the fan-speed signal is synthesized so the firmware is happy.\u003c\/p\u003e\n\u003ch3\u003eRelated Whatsminer Immersion \/ PSU Parts\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/whatsminer-m50-conductive-copper-sheet-p221b-p222b\"\u003eWhatsminer M50 Conductive Copper Sheet – P221B \/ P222B\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/whatsminer-brand-new-p222b-power-supply-unit-psu\"\u003eWhatsminer P222B Power Supply Unit\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/vf60381bx-q23u-s9h-whatsminer-power-supply-p221-p222-6cm-fan\"\u003eWhatsminer P221 \/ P222 6cm PSU Cooling Fan\u003c\/a\u003e\u003ca href=\"\/products\/fan-simulator-plug-and-play-water-oil-immersion-cooling-4pin-square-avalon-lovecore\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eConvert your Whatsminer PSU to silent immersion operation.\u003c\/strong\u003e Order now or \u003ca href=\"mailto:contact@lys-sz.com\"\u003econtact us at contact@lys-sz.com\u003c\/a\u003e for cable-version confirmation and bulk pricing.

Confirm in the dashboard that the fan reaches normal RPM within 5-10 seconds and that hashboard temps stay within their target range.\u003c\/p\u003e\n\u003ch4\u003eKZ14038B012U 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;\"\u003eKZ14038B012U (6-pin variant)\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;\"\u003e7.2A\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;\"\u003e6-pin (Whatsminer M20 \/ M21 pinout)\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 \/ M20S \/ M21 \/ M21S\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 140mm Whatsminer Fans \u0026amp; Adapters\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\/gh14038bzw-14cm-14038-high-speed-cooling-fan-8000rpm-whatsminer-avalon\"\u003eGH14038BZW-1 140mm Fan – Whatsminer M20-M60\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/whatsminer-cooling-fan-adapter-cable-6pin-4pin-control-board\"\u003eWhatsminer 6-pin to 4-pin Fan Adapter Cable\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/6pin-whatsminer-fan-simulator-immersion-cooling-m31-m31s\"\u003eWhatsminer 6-pin Fan Simulator – Immersion Cooling\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eRestocking 6-pin KZ14038B012U fans for an M20 \/ M21 fleet? \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":"Default Title","offer_id":42303388582067,"sku":null,"price":9.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/6710\/4179\/files\/KZ14038B012U-12V-Ball-Bearing-Cooling-Fan-14cm-Whatsminer-M20-M21-series-6pin-Power-Interface_6.webp?v=1744698625"},{"product_id":"c19-female-power-plug-socket-adaptor-for-ac-cord-250vac-16a-whatsminer","title":"C19 Female Power Plug Socket Adaptor for AC Cord 250VAC 16A Whatsminer","description":"\u003ch2 style=\"text-align: left;\" data-mce-fragment=\"1\"\u003eUpgrade Your Power Connections with the C19 Female Power Plug Socket Adaptor\u003c\/h2\u003e\n\u003cp data-mce-fragment=\"1\"\u003eUpgrade your power connections with the \u003cstrong\u003ereliable C19 female power plug\u003c\/strong\u003e socket adaptor.
