Fan Extension Cable Kit

This pack supplies five 12 inch 4 pin PWM extension cables for routing case or CPU fans inside a computer chassis. Each cable splits one female connector into two male connectors so a single header can drive a pair of fans. The black sleeving matches typical build aesthetics.

Length And Splitter Headroom

At 26.2 cm each cable reaches from a motherboard header to fans mounted at the top or rear of mid tower cases without tension. The one to two splitter works while both fans draw within the header current limit; exceeding that limit will cause the header to shut down or throttle.

Five Pack Value

Five cables in one package let builders wire multiple fan pairs or keep spares for future upgrades. No software or additional adapters are included so the only change is physical cable reach and header sharing.

Questions about this item

Will the 12in 4-pin PWM extension reach my rear case fan when routed behind the motherboard tray?

Each cable measures 26.2cm, so a rear-exhaust fan mounted at the top or bottom of a standard ATX chassis can be connected without tension.

How can I confirm the PWM signal is passing through the splitter after I plug it in?

In the BIOS or fan-control software, set the header to PWM mode; both attached fans should then report identical RPM curves and respond to the same duty-cycle changes.

The pack lists five cables — do I need any extra connectors or adapters to run two fans from one motherboard header?

No extra parts are required; every cable already splits one 4-pin female into two 4-pin males, so five motherboard headers can each drive two fans.
