Whatsminer Fan Adapter Cable 4-Pin Male to 6-Pin Female
The Whatsminer Fan Adapter Cable bridges a 4-pin male connector (control-board side) to a 6-pin female connector (fan side). It lets you connect a 6-pin Whatsminer cooling fan into a 4-pin control board header without splicing or re-pinning the harness.
Repair shops use this adapter when swapping older 4-pin Whatsminer chassis fans for newer 6-pin units, or when stock 4-pin fans are spec-out but only 6-pin replacements are available. Plug-and-play, no firmware change required.

Compatibility
Designed for Whatsminer cooling fans using the 6-pin linear connector, mated against a Whatsminer 4-pin control-board fan header. Confirm pin keying on your fan and your control board before purchase — Whatsminer ships both 4-pin and 6-pin variants depending on the chassis generation.
Where the adapter fits
One end of the adapter plugs into the existing 4-pin male header on the Whatsminer control board; the other end accepts the 6-pin female connector from the replacement fan. The adapter is short enough to route inside the chassis without blocking airflow. For the reverse direction (6-pin male to 4-pin female), see the related Whatsminer adapter cable below.
Common failure symptoms before adapter use
- Replacement fan ships with a 6-pin connector but the control board only exposes 4-pin headers
- Mismatched fan throws a fan-stop alarm at boot due to no pin coverage
- Repair shop has bulk 6-pin Whatsminer fans on shelf but legacy 4-pin chassis to retrofit
- Mixed fleet of M20/M21/M30/M31/M50 units with inconsistent fan-header generations
- Operator wants to avoid splicing or de-pinning the original Whatsminer harness
Frequently asked questions
Does this adapter carry PWM and tach signals?
The adapter routes the conductors present on both ends so the control board can read tach and command speed where supported. Confirm your specific fan and header pinout before ordering — Whatsminer fan headers differ slightly between generations.
Will it fit Antminer or Avalon fan headers?
No — the connectors are sized and keyed for Whatsminer. Antminer and Avalon use different fan headers; see the dedicated 4-pin linear to square ATX adapter kit in related products.
Can I use this on the PSU fan header?
The adapter is built for control-board fan headers, not PSU-internal fan harnesses. For PSU fan refresh, use the OEM 2-pin or 4-pin PSU fan directly soldered to the PSU PCB header.
What if my fan is 6-pin male and the board is 4-pin female?
Use the reverse-direction Whatsminer Fan Adapter Cable 6-Pin to 4-Pin listed in related products.
