Two-fan PWM splitter cable for ATX cases

This TeKit 2-pack provides two Y-cables that each connect a pair of case fans to one motherboard 4-pin header. Builders expanding airflow in a standard ATX chassis can run both fans from a single PWM channel. The 25 cm length suits typical internal routing without excess slack.

Black-sleeved 10 cm leads

Each splitter carries a 4-pin female connector on the motherboard side and two fan leads — one 4-pin, one 3-pin — so the board reads RPM from the first fan while the second follows the same PWM duty cycle. The sleeved 10 cm tails keep the wiring tidy in open or windowed cases.

4-pin header with dual-fan PWM sync

The decisive spec is the master-slave pinout: only the first fan reports speed to the motherboard, forcing both fans to spin identically. Buyers who need independent speed curves per fan or who must monitor RPM on every connected fan cannot use this cable.

Questions about this item

Will the splitter's connectors wear out if I reconfigure fans later?

The cable uses a 4-pin female header and two 3-pin male plugs rated for standard motherboard fan headers; normal reconnection cycles are well within their design life.

What limits how many fans I can chain from one header using this splitter?

The motherboard header's current rating is the limiting factor; this splitter passes the PWM signal to two fans but does not increase the header's power budget.

How much heat does the cable add when both fans run all day?

The 25 cm sleeved cable adds negligible resistance, so it does not generate measurable heat during continuous operation.
