140mm 7500rpm Mining Cooling Fan

The SXDOOL PFC1412HE-00 is a 140mm case fan designed for high-static-pressure airflow in mining rigs such as the M30 and M31S. It spins at 7500rpm to deliver 380cfm at 15mmH₂O pressure. The unit runs on 12V DC with a 9A maximum draw and uses a dual ball bearing rated for 50000 hours.

6-Pin PWM Installation and Wiring

The fan connects via a 6-pin header providing two 12V lines, two grounds, a tachometer signal and a PWM control line. Correct polarity is essential; reversing the red and black wires can damage the motor or controller. The 38mm thickness requires clearance verification before mounting in standard chassis slots.

Suited for High-Density Mining Rigs

This fan suits operators replacing original coolers in compatible ASIC miners who need maximum airflow at 59dBA noise levels. It is not intended for quiet desktop builds, standard PWM headers limited to lower amperage, or enclosures that cannot accommodate a 38mm thick frame.

Questions about this item

How can I confirm the fan is running at the specified 7500 rpm after installation?

Connect the yellow tachometer wire to a motherboard header or fan controller and monitor the reported RPM in BIOS or software; it should read approximately 7500 rpm.

What comes with the PFC1412HE-00 and what must I source separately?

The fan unit includes the 6-pin connector with dual power, ground, tach and PWM wires; mounting screws and a PWM-capable 12 V power source are not included.

Which version suits a Bitmain M30 or M31S miner?

The PFC1412HE-00 is built for M30 and M31S models, delivering 380 cfm at 7500 rpm with a 6-pin PWM interface that matches those miners' fan headers.
