Frequently asked questions
Which Whatsminer models is this fan for?
The KZ14038B012U fits the Whatsminer M20 / M21 / M30 / M31 / M32 / M50 / M60 series. Older M20 / M21 use the linear 6-pin KF2510 plug, while M30 through M60 generations use the square 4-pin 5557 plug.
Can I mix this fan with other 140mm Whatsminer fans?
Yes, provided the replacement fan matches the 7200RPM / 300CFM / 12V 7.2A class. Mixing different RPM specs across the four fan positions will trigger controller warnings and unbalanced cooling.
Is the fan original or a clone?
This is the authentic KZ-branded KZ14038B012U, the same reference shipped in the original Whatsminer enclosures.
What lead time should I expect for bulk orders?
Lead time depends on quantity and stock at order time. For farm-scale fan swaps, contact us with the model breakdown and we will quote turnaround along with shipping options.
