Internal Power Cable DeLOCK 89343 0.22 m

The DeLOCK 89343 internal power cable is a 0.22 m Molex 3‑pin lead intended to connect two 3‑pin Molex fans to a motherboard. It supplies voltage to both fans while forwarding the tachometer (speed) signal from one of the fans to the mainboard, enabling fan speed monitoring and stable power distribution inside the PC chassis.

Advantages

This cable allows two fans with a Molex 3‑pin interface to be powered from a single motherboard header, reduces cable clutter with a short 0.22 m length, and maintains the tachometer signal from one fan so the system can read fan speed. The multicolour connector and compact design make it suitable for tight internal routing and varied system builds.

Suitable for (tasks / use cases)

• Connecting two Molex 3‑pin fans to a single motherboard header
• Power distribution for case cooling inside desktop PCs
• Small-form-factor or standard builds where short internal cables are required

How to use

Align and plug the Molex 3‑pin connector into the motherboard fan header or compatible fan controller. Connect the two fan connectors to the cable’s outputs, ensuring correct orientation of the 3‑pin housings. Verify that the fan with the tachometer output is connected to the lead that transmits the speed signal to the motherboard. After installation, power on the system and check BIOS or monitoring software for fan speed readings.

Recommendations

Use this cable inside the PC case only. Avoid stretching the cable or routing it near high‑temperature components. Confirm connector pin alignment before applying power and ensure that the combined current draw of both fans does not exceed the motherboard header or controller specifications.
