VF60381BX-Q23U-S9H Whatsminer PSU Cooling Fan | 60×60×38mm for P221 / P222 Series
The VF60381BX-Q23U-S9H is the 60×60×38mm cooling fan used inside the Whatsminer P221C, P222C, P221B, and P222B power supplies. The fan moves air across the PSU's internal heatsinks during continuous mining duty — when it fails, the PSU goes into overtemperature shutdown within minutes under load.
Electrical: DC 12V, 22.8W, 4-pin PWM connector with tach feedback (the PSU controller monitors the fan-speed signal and will trip a fan-error if no tach is present).
When to Replace the VF60381BX-Q23U-S9H
- PSU overtemperature shutdowns under load — fan dead, seized, or not maintaining required RPM.
- Audible bearing wear — grinding, ticking, or fluctuating speed before complete failure.
- Fan-error reported in miner log — controller can't read tach signal.
- Visible damage — broken blade, melted housing, or dust-clogged hub.

FAQ — VF60381BX-Q23U-S9H Fan
Q: How do I replace the PSU fan safely?
A: Power off and unplug the PSU from the miner and AC mains. 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.
Q: Will a generic 60×60×38mm 12V fan work?
A: 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.
Q: How long do these PSU fans typically last?
A: Under continuous mining duty in typical farm conditions, expect 18-30 months MTBF on the fan bearings. Dust accumulation accelerates wear — preventive cleaning extends life.
Q: Bulk pricing?
A: Yes — email contact@lys-sz.com for volume pricing.
