KF2510 4P Straight Vertical Connector 2.54mm Pitch — Cooling Fan Socket
The KF2510 is the de-facto 2.54mm-pitch wire-to-board connector family used across most ASIC control boards for cooling-fan headers and low-current signal harnesses. This 4-pin straight (vertical) male variant is the part you need to re-pin a damaged fan header on a control board or to build a custom fan harness for a repair bench, simulator board or fan-extension cable.
Tight contact geometry and solid 9-12A current handling make it a reliable choice for the linear 4P fan connectors found on legacy Antminer, Whatsminer M20-series and many silencer / simulator setups.

Where the KF2510 4P sits in an ASIC miner
The KF2510 4P linear connector is the fan header on a wide range of older ASIC control boards — most notably the linear 6P / linear 4P fan ports on Whatsminer M20 / M21 series control boards and on several Antminer and Avalon controllers from the 12V fan era. It is also the connector used on most third-party fan simulators, blower silencers and adapter cable kits for crypto miners.
Typical use cases on a repair bench
Common reasons to keep a stock of KF2510 4P verticals on hand: rebuilding a fan header that has been ripped off the control board, re-terminating a fan extension or simulator pigtail, replacing a melted female-mate header, or building a custom test harness for bench-running PSU + control board combinations.
Common failure symptoms (where this part is the fix)
- Fan not detected — miner halts with "fan error" because the header pins are bent / oxidised
- Intermittent fan RPM signal due to a cracked solder joint at the connector base
- Header physically broken off the control board during fan removal
- Melted plastic housing from a high-current fan stall
- Loose female mating to a worn male header
Frequently asked questions
Is this the same connector as on the Antminer / Whatsminer fan headers?
The KF2510 2.54mm family is widely used for linear 4-pin fan headers on multiple ASIC control boards including Whatsminer M20/M21 series. Always cross-check the original part on your specific board before ordering.
Do you sell the matching female crimp housing and terminals?
The female housing, crimp terminals and pre-crimped harnesses are available on request — contact us with your pin-count and quantity.
Can I solder this directly to a PCB?
Yes, it is a through-hole vertical header designed to be soldered into a 2.54mm-pitch PCB footprint.
What's the difference between linear 4P and square 4P?
Linear 4P (this KF2510 family) places the four pins in a single row at 2.54mm pitch. Square 4P (Molex 5557-style) arranges the pins 2×2 and is electrically incompatible — you need an adapter cable to bridge the two.
