Discharge the bulk capacitors with an insulated discharge tool (PSU caps hold dangerous voltage even after disconnect). Open the PSU housing, disconnect the 4-pin fan connector, unscrew the fan, install fresh fan with correct airflow direction matching the original, reconnect and reassemble.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will a generic 60×60×38mm 12V fan work?\u003c\/strong\u003e\u003cbr\u003eA: Possibly, but verify: (1) 4-pin PWM with tach signal — generic fans without tach trip fan-error; (2) airflow rating matches the original (the PSU's thermal design assumes a specific CFM); (3) connector pinout matches.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How long do these PSU fans typically last?\u003c\/strong\u003e\u003cbr\u003eA: Under continuous mining duty in typical farm conditions, expect 18-30 months MTBF on the fan bearings.
