PWM 1-to-3 fan splitter cable

This EN-Labs 1X3PWM15CM cable connects three PWM case fans to a single motherboard 4-pin header. It suits builders who need extra cooling channels without using additional headers. The 15 cm length keeps routing tidy inside compact cases. All three fans receive the same PWM speed signal from the board.

Master and slave connector layout

One branch carries a full 4-pin connector that reports RPM back to the motherboard. The other two branches omit the sense pin so those fans follow the master speed without individual feedback. This arrangement keeps all fans synchronised while avoiding signal conflicts. The 26 AWG copper conductors handle the combined current draw.

Three fans on one header

The splitter comfortably powers three typical case fans such as 120 mm or 140 mm models from common brands. It runs out of headroom when the total current exceeds what a single motherboard header can supply. Builders needing independent speed curves or more than three fans should use a powered fan hub instead.

Questions about this item

Will the 26AWG copper conductors need replacement after extended use?

The 26AWG copper conductors are rated for continuous operation inside a PC case and do not have a scheduled replacement interval.

What is the combined current limit when three fans draw power through the single motherboard header?

The splitter passes the motherboard header's own current rating; total draw of all three fans must stay within that header's limit.

Does the 15 cm cable add noticeable heat or electrical noise when all three fans run at full PWM speed all day?

The short 26AWG cable adds negligible resistance and no active components, so heat and electrical noise remain minimal under continuous load.
