120 mm 12 V PWM fan cable

This 120 mm internal power cable connects a 12 V PWM case fan to a standard four-pin motherboard header. It is designed for builders adding or replacing a single chassis fan in a desktop system. The cable carries both power and speed-control signals in one run.

Simple plug-in install with one common snag

Installation is a straightforward push-fit onto the fan and motherboard header; no tools are required. The only frequent issue is reversed orientation — the keyed connector must match the header notch, otherwise the fan will not spin or report speed.

Questions about this item

How can I confirm the 12 V fan is spinning correctly after installation?

Connect the 4-pin PWM header to the motherboard and verify RPM in BIOS or monitoring software; the fan should report speed and respond to PWM curves.

Does the package include only the 120 mm fan or are mounting screws and a PWM splitter also supplied?

The box contains the 120 mm 12 V PWM fan; mounting screws and any splitter cables are not included and must be purchased separately.
