Five cables for fan reach

This pack supplies five 15.7 inch extension cables that connect a motherboard or controller header to a case or CPU fan. Each cable carries a TX4 four-pin male plug on one end and a TX4 four-pin female socket on the other. The black sleeved braid keeps routing tidy inside an ATX build. They are sold new and ready for immediate installation.

Extends PWM control by 15.7 inches

The copper conductors deliver 12 V and 5 V DC while preserving the PWM signal so fan speed remains under automatic control. A 3-pin TX3 fan will also run from the female end, though speed regulation then depends on voltage rather than PWM. The extra length clears large coolers or rear-exhaust layouts where the stock lead falls short. Builds that need longer runs or more than five connections will require additional cable.

TX4 male to TX4 female pinout

The decisive specification is the connector pairing: a four-pin PWM male header mating with a four-pin PWM female header. This matches standard motherboard fan headers and most modern case or cooler fans. If the target device uses a proprietary connector, a different adapter is necessary.

Questions about this item

Will the 15.7-inch extension reach a rear-mounted fan when routed behind a full-size ATX motherboard tray?

The 15.7-inch length adds enough slack to route behind a standard ATX tray and reach rear or top exhaust fans without tension.

How can I confirm the PWM speed signal is passing through the cable after installation?

In BIOS or fan-control software the connected fan should report RPM changes when the PWM duty cycle is adjusted, proving the fourth wire is active.

Does the pack include any adapters for 3-pin headers or must I buy them separately?

Each cable has a TX4 female end that accepts a 3-pin fan plug directly, so no separate adapter is required for 3-pin fans.
