HETAI Digital Technology Co.,Ltd 1-to-5 4-pin PWM fan splitter cable 39.5cm

One header to five PWM fans

This splitter cable turns a single motherboard 4-pin PWM header into five fan connections, letting enthusiasts run multiple case or CPU coolers from one control point. The 39.5 cm braided lead reaches across full-tower layouts while keeping cable routing tidy. A dedicated RPM sense wire on the first channel feeds a single speed reading back to the board. All five ports accept both 3-pin and 4-pin fans.

Steady 12 V delivery across all ports

The hub draws DC 12 V straight from the motherboard header and distributes it to every attached fan without an external power connector. PWM signalling reaches all five outputs so the board can ramp every 4-pin fan together under sustained load. Connected 3-pin fans receive constant voltage and therefore run at full speed regardless of the PWM duty cycle. The compact PCB keeps voltage drop low over the 400 mm total length.

Replaces daisy-chained Y-splitters

Builders who have been stacking dual or triple Y-cables can consolidate to this single five-way hub, reducing connector count and eliminating the signal conflicts that arise when multiple RPM wires are paralleled. The upgrade is worthwhile when fan count exceeds two per header or when cable clutter blocks airflow in tight channels. Systems that need independent speed curves per fan still require additional motherboard headers or a controller with multiple PWM outputs.
