The YD4028HBL is a 40 × 40 × 28 mm cooling fan sized for the Bitmain APW8, APW9 and APW9+ power supply units. The fan sits at the PSU exhaust, evacuating heat from the high-power switching components on the secondary side — quiet, reliable operation keeps the PSU running cool under continuous mining load.
Electrical: 12 V / 0.30 A — drawn directly from the PSU's internal housekeeping rail. Compact 28 mm depth fits the slim Bitmain PSU enclosure profile. Quiet operation also helps when the PSU is deployed in semi-residential or noise-sensitive sites.
Typical Use Cases
Failed PSU fan replacement — Bitmain APW8 / APW9 OEM fan worn out.
Bearing noise reduction — replace rattling factory fans with fresh unit.
PSU rebuild lines — bulk fan inventory for refurb stations.
Site service kits — common-failure spare for field maintenance.

FAQ — YD4028HBL PSU Fan
Q: APW8 vs APW9 fan position — same? A: Yes — both PSUs use the same 40 × 40 × 28 mm fan at the exhaust position. Drop-in replacement.
Q: Will it fit APW12 / APW17? A: No — those PSUs use larger 60 × 60 × 25 mm fans (YD6025HSL family). Check the PSU model before ordering.
