KY12038B12DN 120mm Cooling Fan 12V 2.8A | Antminer S21 S19 L7 KA3 KS3 Replacement
The KY12038B12DN is a 120mm high-performance cooling fan designed as a direct replacement for damaged or worn-out fans across a wide range of Antminer models: S21, T21, S19, S19j, S19 Pro, S19 XP, S17 Pro, T17+, L7, D7, KA3, KS3, T19, and the full 17 and 19 series. Running at 12V with 2.8A draw, it delivers 267 CFM airflow at 6000 RPM through high-precision double ball bearings for extended lifespan. PWM temperature control and speed measurement provide intelligent cooling management.
KY12038B12DN Fan: 267 CFM Airflow with Double Ball Bearings
The double ball bearing construction is critical for mining fan longevity — sleeve bearing fans typically fail within 6-12 months in the continuous 24/7 operation and dusty environments common in mining facilities. Ball bearings last significantly longer and maintain consistent airflow throughout their lifespan. The 6000 RPM motor pushes 267 CFM through the 120×120×38mm frame, matching or exceeding the stock fan specifications on all supported Antminer models. The 65 dBA noise level is standard for high-performance mining fans.

Antminer Fan Replacement & Cooling Alternatives
A failing fan causes overheating, thermal throttling, and eventual miner shutdown. Replace immediately when you notice increased noise, vibration, or rising chip temperatures. The KY12038B12DN is a drop-in replacement — disconnect the old fan, connect the new one, and the miner's PWM controller automatically adjusts speed based on temperature. For S21-specific fans, see the Delta PFM1412DE 140mm S21 Fan. For Avalon miners, the Avalon 120mm 12V 9A Fan covers the 1346/1366/1466/1566 series. For noise reduction, the Gen2 ASIC Miner Blower Silencer fits most major miner brands.
