Overview
MARTECH 120 mm PWM miner cooling fan
This high-speed axial fan is built for heat removal in compatible ASIC mining systems. Its rated specifications are 120 × 120 × 38 mm, 12 V DC, 2.7 A, 32.4 W and 6000 RPM, with four-wire PWM speed control and double-ball-bearing construction.
Match the installed fan
Select the required miner group, square 4-pin or 4-pin connector, and Original or Replica option. Compare the original fan label, mounting pattern, connector housing, electrical pinout and airflow direction because connector shape alone does not confirm wiring.
Install and test
Disconnect mains power, preserve the required airflow direction and keep the cable clear of the blades. After startup, confirm fan detection and stable speed reporting before returning the miner to service.

The unit price applies to one fan. The minimum order quantity is 10.
