Phobya 4-Pin PWM Fan Splitter

This Phobya splitter connects up to four 4-pin PWM case fans to a single motherboard header. The board delivers power to every attached fan and forwards the PWM signal from the first fan to all four outputs. Model 1011223 ships in black and is sold new as a case accessory.

PCB Mounting and Cable Management

The compact PCB includes adhesive tape for tool-free placement anywhere inside the chassis, plus two screw holes for a fixed mount. Consolidating four fan cables onto one board reduces clutter and simplifies routing behind the motherboard tray. A separate 4-pin PWM male-to-male cable is required to link the splitter to the motherboard header.

Replaces Individual Fan Headers

Builders who have exhausted motherboard fan headers can run four fans from one PWM source without adding a powered hub. The jump is worthwhile when all fans should follow the same speed curve and the motherboard header can supply sufficient current for the combined load. It does not suit setups needing independent speed control per fan.

  • Powers all four fans while mirroring the first fan's speed signal
  • Black PCB with adhesive backing for flexible case mounting
  • Optional screw holes provide a secure alternative installation method
  • Simplifies cable routing for cleaner internal airflow management

Questions about this item

What is the maximum number of 4-pin PWM fans the Phobya 1011223 splitter can power at once?

The Phobya 1011223 splitter can supply up to four 4-pin PWM fans simultaneously with power and transfer the PWM signal from the first fan to all four connected fans.

Does the Phobya 1011223 splitter generate noticeable noise or heat during continuous operation?

The Phobya 1011223 is a passive PCB splitter with no moving parts, so it produces no audible noise and negligible heat during all-day use.

Which cable must I already have to connect the Phobya 1011223 splitter to the motherboard?

You need a 4-pin PWM male-to-male cable to link the splitter's input connector to the motherboard fan header.
