Cable extension DELOCK 90868 for computer cooling systems, PVC sleeve, 1.3 mm diameter, multicolour

DELOCK 90868 is a 4‑pin cable extension designed for computer cooling systems and other applications that require a reliable fan connection. The conductor has a diameter of 1.3 mm and the cable is sleeved with polyvinyl chloride (PVC). The product is supplied as a single piece in a polybag and is available in five colours: black, blue, red, white and yellow. This cable extension enables extending or replacing wiring in fans, cooling assemblies, 3D printers and DIY electronics projects where a 1.3 mm conductor is specified.

Advantages

The PVC sleeve provides insulation and basic mechanical protection while remaining flexible for routing inside enclosures. A 4‑pin fan connector format preserves standard signal and power contacts for PWM fans and similar devices. Colour options allow easy identification of wires or visual matching with existing cabling. Supplied as a single, ready‑to‑use piece in a polybag, it is suitable for straightforward replacement or extension without additional preparation.

How to use

Identify the fan header and the fan connector that require extension or replacement. Match the 4‑pin connector orientation to the header pins to preserve correct power, ground and signal alignment. Route the cable through the chassis or assembly ensuring the PVC sleeve does not get pinched or excessively bent. Connect the extension between the fan and the header, verifying secure seating of the connector. If necessary, secure the cable with a cable tie or adhesive clamp to prevent movement during operation.

Recommendations

Use this cable extension only within its intended low‑voltage DC cooling and signal applications. Avoid exposing the PVC sleeve to high temperatures or sharp edges that could damage the insulation. For reliable PWM control, ensure connectors are fully seated and pins are aligned correctly. Choose the cable colour that best fits your wiring scheme for easier maintenance and identification.
