Delock PWM Cable for CPU & Case Fan, 10 cm, 4-Pin

Delock PWM Cable for CPU & Case Fan – 10 cm 4-Pin Extension for Flexible Fan Power Routing

The Delock PWM extension cable is a 10 cm short cable with 4-pin PWM connectors on both ends, designed to bridge the gap between a motherboard's fan header and a CPU or case fan that sits further away. It enables precise fan speed control via the PWM signal while keeping the cable run tidy and within reach.

• 10 cm length provides just enough reach to reposition a fan connector without straining the motherboard header
• 4-pin PWM on both sides preserves full speed-control functionality, unlike 3-pin cables that lose PWM signalling
• Compatible with standard PWM 4-pin CPU and case fans — no adapter or converter needed
• Compact, low-profile design keeps cable management clean inside the PC case

What sets this cable apart

Unlike generic extension cables that may drop the PWM signal or force a 3-pin-to-4-pin workaround, this Delock cable maintains the full 4-pin PWM connection on both ends. The 10 cm length is purpose-built for tight internal layouts where a few extra centimetres make the difference between a clean build and a strained connector.

Ideal for

PC builders and upgraders who need to extend a fan connection by a short distance — especially in compact cases or when routing cables behind the motherboard tray. Suitable for anyone assembling or maintaining a desktop PC with standard PWM-controlled fans.

Application of the Delock PWM Cable

1. Connect the 4-pin PWM end to the motherboard's CPU_FAN or CHA_FAN header
2. Route the 10 cm cable to the fan's location inside the case
3. Plug the fan's 4-pin PWM connector into the other end of the cable
4. Verify in BIOS or software that the fan is detected and PWM control is active
