D12BM-12D 120mm 4400 RPM Cooling Fan – Antminer L3+ / S9 / Whatsminer M3
The D12BM-12D is a high-speed 120 × 120 × 38 mm ASIC miner cooling fan built for repair and replacement of failed factory fans on Bitmain Antminer S7, S9, L3+, T9+, Whatsminer M3 and Ebang Ebit E9+. Durable ball-bearing design delivers high air volume and efficient cooling at the 4400 RPM rated speed under continuous mining load.
Electrical spec: 12 V / 2.3 A, 4-pin connector + 4-wire harness for direct drop-in replacement on most older ASIC miners and CPU coolers. The 38 mm depth provides extra blade volume for higher static pressure through the heatsink fin stack.
Typical Use Cases
- Failed factory fan replacement — old Antminer S9 / L3+ chassis fans wearing out.
- Higher-airflow upgrade — replace lower-speed OEM fans with 4400 RPM unit.
- Fleet field service — common-failure spare for site-maintenance kits.
- Refurb / resale — fresh fans on older miners going back to market.

FAQ — D12BM-12D Cooling Fan
Q: Replacing both intake + exhaust fans — same SKU?
A: Most older Antminers use the same fan SKU for both positions. Confirm the existing fan's part number and dimensions before ordering — some chassis use different intake/exhaust models.
Q: 4-pin PWM control supported?
A: Yes — 4-pin connector includes PWM signal wire so the control board can throttle speed dynamically based on hashboard temperature.
Q: Bulk pricing?
A: Yes — email contact@lys-sz.com.
