Description Bitaxe Fan by Caizhu-Fan: 40×40×20 mm, 5 V DC High-Performance Bitaxe Replacement Fan for Max, Ultra, Supra, & Gamma Upgrade your miner’s cooling with the exact OEM Bitaxe replacement fan designed for every single chip Bitaxe model. This Bitaxe fan keeps your ASIC stable and quiet, even during heavy overclocks. Detailed Overview Precision OEM Engineering Caizhu-Fan manufactures this 40 mm Bitaxe replacement fan on fully automated lines to ISO-certified tolerances. The dual-ball-bearing hub is rated for 70,000 hours of continuous duty at 45 °C inlet temperature, ensuring years of 24 ⁄ 7 mining without bearing squeal or shaft wobble. Brushless Efficiency A sensor-less three-phase driver eliminates brush arcing, lowering electrical noise that can corrupt BM1370 hash calculations. The five aero-profile blades generate up to 9 CFM at 7,500 RPM yet draw only 0.24 A from the 5 V rail, preserving power budget for overclocking. Perfect Thermal Match for Dark Horse Mounted on the Dark Horse pin-fin heatsink, the concentrated airflow penetrates the dense fin field, and sweeps heat off hotspots on the ASIC, VRMs, and MOSFETs. Plug-and-Play Installation A four-pin Micro JST or PWM connector mates directly with the Bitaxe PCB header; no crimping or soldering. Four self-tapping screws index into standard 40mm heatsink bosses, so the swap takes less than two minutes.
