PFC1212DE is a heavy-duty high-speed 12038 axial fan sized at 120x120x38mm. It runs at DC12V 4.80A and reaches up to 7000RPM to produce ultra-high airflow and static pressure. Equipped with dual ball bearings, this fan can sustain nonstop 24-hour operation under high-load mining environments. It efficiently expels massive heat from Antminer S7, S9, D3, L3 and E9, preventing overheating and hash drop caused by high temperature. Standard mounting spacing allows simple direct swap for old failed fans, an essential aftermarket spare part for mining rig repair and upgrade.
