YD120625BH 60mm PSU Cooling Fan for Bitmain APW12 / APW17
The YD120625BH is a 60x60x25mm 12VDC cooling fan built into the Bitmain APW12 1215a and APW17 1215a power supplies. With a 5000 RPM rated speed and a draw of 0.38A at 12V, it provides the focused airflow needed to keep the PSU's primary-side MOSFETs and secondary-side rectifiers within thermal limits during 3000-3600W continuous output.
A dead or seized PSU fan is the most common root cause of thermal shutdowns on aging APW12 / APW17 units — the PSU runs hot enough to trip its over-temperature protection within minutes of boot. Swapping in a fresh YD120625BH is a quick, low-cost fix that restores normal duty cycle without a full PSU replacement.

Compatibility
The YD120625BH 60x60x25mm form factor matches the internal fan slot of the APW12 1215a and APW17 1215a PSUs. For the 6025 alternative used on the same APW12 / APW17 platforms, see the YD6025HSL / HD6025M12B options in related products.
Where the YD120625BH fits
The fan is mounted internally inside the APW12 / APW17 chassis, blowing across the primary-side MOSFETs, EMI filter section and secondary-side rectifier heatsinks. Replacement requires opening the PSU shell — discharge the bulk caps before working inside, and unsolder / re-solder the 2-pin power lead to the PCB header (or splice with crimped Faston terminals).
Common failure symptoms
- PSU runs hot to the touch within 5-10 minutes of boot
- Over-temperature shutdown logged by the miner controller
- Audible bearing rattle or grinding from the PSU enclosure
- Fan visibly stalled when looking through the PSU exhaust grill
- PSU output sags under load — secondary-side rectifier overheating
Frequently asked questions
Does the YD120625BH come pre-wired?
Yes — the fan ships with a short pigtail. Most APW12 / APW17 repairs require splicing or re-soldering to the PSU's internal 2-pin fan header. Confirm polarity before powering up.
What's the difference between YD120625BH, YD6025HSL and HD6025M12B?
All three are 60x60x25mm 12V 6025-class PSU fans for the APW family. RPM ratings and bearing types vary — match against the spec label on the original fan, or contact us with a photo.
Is this the same fan used on APW3 / APW7?
APW3 and APW7 PSUs typically use a different 60mm or 80mm fan variant. For APW3 / APW7 fan refresh, see the HD6025M12B, FD6025B12H or PSAD16025BM options.
Can I run this fan at higher voltage?
No — 12V DC rated. Overdriving it will burn the bearing and the motor windings within minutes.
