Micro Connectors PWM-103BK 10cm 4-Pin internal power cable

SKU CH-6SA9-JH9SX MPN PWM-103BK.

Splits one motherboard PWM header to three fans with 10 cm sleeved cables

  • ColorBlack
  • Splits one PWM header into three fan connections
  • 10 cm length keeps cable routing tidy inside the case
  • Black weave sleeving protects wires and looks clean
  • Works with both 4-pin PWM and 3-pin fan connectors
  • Supplied as a two-pack for multiple fan setups

1-to-3 PWM fan splitter

This black sleeved cable splits one motherboard 4-pin PWM header into three fan connectors. Each branch accepts a 4-pin PWM fan or a 3-pin fan connector. The 2-pack provides two identical splitters for multi-fan configurations. Builders who need more than three fans per header cannot use this cable.

Sustained signal integrity

The premium weave sleeving protects the conductors during continuous operation inside a chassis. PWM control signals pass through to all three fans without degradation over typical internal cable runs. The 10 cm length keeps routing tidy for standard motherboard header placement. Systems that require longer reaches between header and fans will find the fixed length limiting.

Build quality and daily use

Black weave sleeving resists abrasion and keeps the three leads bundled for clean cable management. Each splitter terminates in three female 4-pin connectors keyed for PWM fans. The connectors seat firmly on standard 4-pin headers and 3-pin fans alike. Installers who prefer individual sleeved wires rather than a bundled loom will want a different style.

Questions about this item

Does the 10 cm sleeved PWM-103BK add noticeable heat or noise when three fans run all day?

The cable itself is a passive 10 cm assembly with premium weave sleeving; it draws no power and generates no heat or noise beyond what the connected fans produce.

What must my motherboard already provide for the PWM-103BK to control three fans?

A single 4-pin PWM header supplies the control signal that the splitter distributes to all three fan connectors.

Will the PWM-103BK work with the 3-pin fans I already own alongside a new 4-pin model?

Yes — the splitter accepts both 4-pin PWM and 3-pin fan connectors, so mixed-vintage fans can share the same motherboard header.
