Molex to Dual TX4 Fan Splitter

This 10-inch cable converts a single Molex LP4 connector into two TX4 fan headers. It is intended for builders who need to run additional case fans from a power-supply Molex lead without using motherboard headers. The black sleeved jacket protects the 22AWG copper conductors inside. Power is drawn directly from the PSU 12V rail.

No PWM Speed Control

Only two pins on each TX4 connector are energised so the fans receive constant 12V power. There is no ability to throttle fan speed or use PWM control regardless of the header type. Fans will spin at full voltage for the duration of the session. The 100% copper core and UL 1007 22AWG wire gauge handle the sustained current without voltage drop.

Single Molex Source Limitation

The splitter draws all power from one Molex connector rated for 12V delivery. Builders who need independent speed curves per fan or motherboard-reported RPM cannot use this adapter. It suits setups where constant maximum airflow is acceptable and no fan-speed monitoring is required.

Questions about this item

How much power does the Molex-to-TX4 splitter draw when two fans run continuously?

The cable passes 12 V from the PSU Molex connector; only two pins are energised on each TX4 header, so fans run at full speed without PWM control.

What power connector must the power supply provide for this splitter to work?

A standard Molex LP4 male connector from the PSU is required to supply 12 V to the two TX4 fan headers.

Will my older 3-pin fans run at variable speed when plugged into the TX4 headers?

No — only two pins carry power on each header, so 3-pin or 4-pin fans receive constant 12 V and cannot be throttled.
