Cable extension DELOCK 90871 for computer cooling systems, PVC, 1.3 mm diameter, multicolour

DELOCK 90871 is a 4-pin cable extension intended for computer cooling systems and related PC accessories. The PVC-insulated conductor has a 1.3 mm diameter and is supplied as a single piece in a polybag. Available in black, blue, red, white and yellow, this multicolour fan extension is designed to extend or replace short fan or signal leads during case assembly, maintenance or small electronics projects.

Advantages

The cable extension provides a simple and reliable method to increase reach between fans and motherboard or controller headers without modifying original wiring. PVC insulation offers basic mechanical protection and flexibility while maintaining a compact 1.3 mm conductor profile. The availability in five colours supports colour-coding for easier cable management and identification in multi-fan setups or custom builds.

Key specifications

How to use

Connect the male end of the extension to the fan header and the female end to the motherboard or controller header, ensuring correct pin alignment for power, ground, tachometer and PWM signal. Verify secure seating of connectors to prevent intermittent contact. Route the cable to avoid sharp edges, moving parts, or high-temperature components and secure it with cable ties if necessary. If multiple extensions are used in series, confirm signal integrity and fan control functionality after installation.

Recommendations

For reliable operation, use the cable within typical PC internal temperature ranges and avoid exposing PVC insulation to direct heat sources. Choose a colour that matches your cable management scheme to simplify identification. Avoid excessive bending at connector ends and ensure firm, correctly oriented connections to preserve PWM fan control and tachometer readings.
