2-Pack 3-Way 4-Pin PWM Fan Splitter

This 2-pack of 3-way 4-pin PWM fan splitter cables connects three case fans to a single motherboard fan header. Each 12-inch cable splits one 4-pin header into three fan connections for simplified cable routing. The sleeved jacket resists tangles and keeps the interior tidy. It is suited for builders expanding case airflow without adding a dedicated fan controller.

For builders using PWM fans on a PWM header

These splitters suit systems where the motherboard header supports PWM control and can supply enough current for three fans. The master 4-pin connector reports RPM to the board while the two 3-pin branches follow the same speed signal. Builders whose boards lack PWM headers or whose fans draw more than the header can safely provide should look at a powered fan hub instead.

36-watt maximum power rating

The cable assembly is rated for a total draw of 36 watts across all three connected fans. Exceeding this limit risks overheating the splitter or the motherboard header. Verify the combined wattage of your fans before installation to ensure the splitter remains within its rated capacity.

Questions about this item

How much space does the 12-inch cable need inside the case?

Each splitter is 12 inches long with a sleeved jacket; allow enough clearance for the master 4-pin connector at the motherboard header and the three fan branches to reach their mounts without tension.

Which fan header pin carries the PWM signal during installation?

The master 4-pin connector receives the PWM control signal from the motherboard and distributes it to all three fans; the two 3-pin branches run at the same speed as the master fan when the board supports PWM control.

When should the splitter be replaced?

Replace the cable if the sleeving frays, connectors become loose, or total fan draw approaches the 36-watt limit, as overheating can damage the motherboard header.
