SHLF1212CHE-03 120mm Cooling Fan 6000RPM – QFR1212GHE Equivalent for Antminer
The SHLF1212CHE-03 is a 120×120×38mm cooling fan rated at 12V / 2.7A, spinning at 6,000RPM with double ball bearing construction. It delivers 210CFM at 64dBA and serves as a direct equivalent to the QFR1212GHE, fitting Antminer miners that use the standard 120×38mm fan form factor. The counterclockwise rotation design matches the Antminer chassis airflow configuration.
Why Double Ball Bearings Matter
Mining fans run at maximum RPM continuously for months. Sleeve-bearing fans degrade quickly — lubricant evaporates, the bearing seizes and the fan stalls. Double ball bearing construction provides a hardened steel race that lasts significantly longer under sustained high-RPM loads, maintaining consistent airflow and quieter operation over the fan's service life.
Installation
Power off the miner. Disconnect the old fan and remove mounting screws. Insert the SHLF1212CHE-03 with the airflow direction matching the chassis configuration (intake or exhaust as applicable). Secure, connect and power on. Verify a stable RPM reading and normal chip temperatures in the dashboard.
