Direct OEM-style replacement when the original cover cracks, gets lost during maintenance, or simply wears out after years of farm duty. Two variants cover the \u003cstrong\u003e4-pin and 6-pin fan-header layouts\u003c\/strong\u003e across the Whatsminer M-series lineup.\u003c\/p\u003e\n\u003cp\u003eWhy this matters for fleet maintenance: control boards exposed to airborne ash, sand, or shed dust degrade much faster than enclosed boards. A missing case lets contaminants accumulate on the SoC heatsink and around the connectors, shortening service life and triggering intermittent communication faults that look like board failures but are actually contamination issues. Replacing the missing cover is a few-dollar maintenance task that prevents much more expensive board replacements down the line.\u003c\/p\u003e\n\u003ch3\u003eWhy You Need This Case\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDust + ash protection\u003c\/strong\u003e — keeps mining-shed contaminants away from the control board's connectors and SoC.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhysical impact protection\u003c\/strong\u003e — survives the bumps and drops of maintenance handling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaintenance cycle efficiency\u003c\/strong\u003e — clean board = faster diagnostic, fewer false-positive failures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-pin \/ 6-pin fan-header variants\u003c\/strong\u003e — match the existing miner's control-board layout exactly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect-replacement design\u003c\/strong\u003e — plug-and-play install, no modification.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eWhatsminer Control Board Case Specifications\u003c\/h4\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\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eControl board protective case\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eWhatsminer control boards (most M-series models)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFan Port Variants\u003c\/td\u003e\n\u003ctd\u003e4-pin (4P) \/ 6-pin (6P) — specify on order\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eDust + debris + impact protection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstallation\u003c\/td\u003e\n\u003ctd\u003eDirect replacement, no modification\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUse Case\u003c\/td\u003e\n\u003ctd\u003eWhatsminer fleet maintenance and refurbishment\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e~0.2 kg\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\u003eFAQ — Whatsminer Control Board Case\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: 4-pin vs 6-pin — how do I know which one I need?\u003c\/strong\u003e\u003cbr\u003eA: Look at the fan-header connector on the existing control board. 4-pin (4P) is the older layout; 6-pin (6P) is the newer Whatsminer M-series convention. Match the existing miner's connector type when ordering — the case cutouts are sized to one layout only and won't fit the other.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will it fit all Whatsminer models?\u003c\/strong\u003e\u003cbr\u003eA: Compatible with most Whatsminer M-series control boards. The 4P \/ 6P split covers the dominant layout variants; if the existing case is missing entirely, hold a replacement next to the board to confirm cutout alignment before powering on.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why does the case affect miner reliability?\u003c\/strong\u003e\u003cbr\u003eA: Mining-shed environments are dirty. Without a case, dust accumulates on connector pins (causing intermittent contact), on the SoC heatsink (causing thermal throttling), and around the I2C \/ UART signal lines (causing communication errors). All three failure modes look like control-board faults on diagnostic, but the root cause is contamination — fixed by keeping the case in place.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Bulk pricing for fleet maintenance?\u003c\/strong\u003e\u003cbr\u003eA: Yes — email contact@lys-sz.com for case-quantity Whatsminer control board case pricing.\u003c\/p\u003e\n\u003ch3\u003eRelated products\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/whatsminer-cb4v10-h6-control-board-m20-m30-m31-m32\"\u003eWhatsminer CB4 V10 H6 Control Board\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/whatsminer-cb6-v5-control-board-m33s-m33s-m53-m53s-m53s-m63-m63s-hydro-miners\"\u003eWhatsminer CB6 V5 Hydro Control Board\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/whatsminer-m60-m50-m30-hashboard-tester\"\u003eWhatsminer M60 \/ M50 \/ M30 Hashboard Test Fixture\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/fan-simulator-water-oil-immersion-cooling-4pin-atx-whatsminer\"\u003eWhatsminer 4-pin ATX Fan Simulator\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWhatsminer fleet operators stocking control board cases by the case?
