Fan PWM Splitter for Mainboards

This 40 cm breakout cable converts a single 4-pin PWM header on a mainboard into three 4-pin PWM headers. It allows simultaneous control and monitoring of up to three fans from one motherboard socket. The cable suits builders who need extra fan connections without adding a separate controller.

Black Sleeved 40 cm Cable

The 1.3 ft length keeps routing tidy inside compact or full-size cases while reaching nearby headers. Black sleeving matches typical internal aesthetics and reduces visual clutter. The 4-pin PWM connectors maintain speed reporting and duty-cycle control on all three branches.

No Extra Software or Adapters Required

The splitter draws fan power directly from the mainboard header, so no external supply or Molex adapter is needed. Builders who require more than three fans or higher current than the header rating permits will need a powered hub instead.

Questions about this item

How many fans can the 4-pin PWM breakout cable control from one motherboard header?

The cable splits one 4-pin PWM channel into three 4-pin PWM headers so you can connect and monitor up to three fans from a single socket.

What length is the Phobya 81123 breakout cable and will it reach across a full-tower case?

It measures 40 cm (1.3 ft) end to end, which typically covers the distance from a motherboard fan header to nearby chassis fans but may fall short for rear or top mounts in large towers.

Do I need to configure anything in BIOS after plugging three fans into this splitter?

No extra hardware setup is required; just plug the single 4-pin end into the motherboard PWM header and attach the three fans, then set the fan curve in BIOS for that header.
