Replacement fan for Antminer S7 S9 OC11

This 12 V cooling fan carries the QFR1212GHE designation and draws 2.70 A through a 4-pin connector. It is built as a direct replacement for Bitmain Antminer S7, S9 and OC11 units and has been well tested for that role. The 12038 form factor matches the original equipment specification.

Miners needing a drop-in 12 V 4-pin replacement

Buyers who need a fan for a different voltage, a different connector layout or a different frame size should look elsewhere. The part is specialised for the listed Antminer models and is not a general-purpose case fan.

Questions about this item

Does this fan need a 4-pin PWM header on the controller board?

Yes, the QFR1212GHE uses a 4-pin connector that plugs directly into a matching header on the Antminer S7, S9 or OC11 controller.

Can I keep my existing Antminer S7 power supply when I fit this replacement fan?

The fan draws 2.70 A at 12 V from the miner's own 12 V rail, so the original power supply remains unchanged.
