PWM 1-to-2 fan splitter for dual-fan headers

This 10 inch PWM Y-cable splits a single motherboard 4-pin header into two 4-pin fan connectors so two fans share one PWM signal. The 22AWG copper conductors carry 12V or 5V power while the black sleeved jacket protects the wiring. Each pack contains two identical splitters for multi-fan configurations. Builders adding a second case or radiator fan without an extra header will find this the simplest solution.

Sustained-load behaviour with shared PWM control

All connected fans follow the same motherboard PWM curve so their speeds rise and fall together under continuous thermal load. The master connector passes the RPM signal back to the board while the slave omits it, keeping both fans in lockstep. Three-pin fans attached to either plug run at full voltage without speed modulation. The 22AWG copper handles the combined current without measurable voltage drop during extended operation.

Plug-and-play install with one monitoring limitation

Each splitter keyed 4-pin plugs mate directly with standard motherboard headers and fan sockets; no tools or adapters are required. The 10 inch length reaches most rear-exhaust or top-mounted fan positions in typical chassis layouts. Only the fan on the master connector reports RPM to the BIOS or software, so the second fan’s speed is inferred rather than measured. Builders needing independent speed curves or per-fan monitoring cannot achieve that with this cable.

Questions about this item

How much heat does the 22AWG copper conductor add when two fans run all day?

The 22AWG copper wire is rated for the 12V and 5V fan currents used here, so it adds no measurable heat inside the case.

What motherboard header do I need for the 4-pin TX4 female connector?

A single 4-pin PWM fan header on the motherboard accepts the TX4 female plug and drives both male fan connectors.

Will my 3-pin case fans still run at full speed when plugged into the male 4-pin plugs?

Yes, 3-pin fans connected to the male plugs run at full constant speed because the PWM pin is absent.
