Cable Silverstone CPL03 0.3 m 4 x 4-pin PWM 4-pin PWM

The Silverstone CPL03 is a 0.3 m cable with four 4‑pin PWM connectors designed to distribute power and PWM control signals to multiple PC fans from a single header. It provides a compact, low-profile connection solution for systems where space is limited, enabling synchronized speed control and consistent power delivery to PWM-capable fans. The cable supports standard 4‑pin fan headers and preserves the PWM signal line for automatic or motherboard-based fan speed control.

Advantages

This 0.3 m 4 x 4‑pin PWM cable offers a simple way to connect up to four PWM fans while maintaining the PWM control line for accurate RPM regulation. Its short length reduces cable clutter and signal degradation in compact builds. The cable is compatible with typical motherboard and controller fan headers and is constructed to provide reliable electrical contacts and stable performance under normal operating conditions.

Suitable for

• Small form factor (SFF) and compact desktop PC builds where short cabling is required
• Connecting multiple 4‑pin PWM fans to a single motherboard or fan controller header
• Systems that require synchronized PWM fan speed control for balanced cooling
• Upgrading or replacing short fan extension or splitter cables inside PC cases

Key specifications

• Cable length: 0.3 m
• Connector type: four 4‑pin PWM fan connectors
• Signal support: PWM speed control line preserved
• Intended use: internal PC fan power and control distribution
• Form factor: low‑profile, short‑reach cable for confined spaces

How to use

Connect the single input end of the cable to an available 4‑pin PWM fan header on the motherboard or a dedicated PWM fan controller. Attach up to four 4‑pin PWM fans to the cable's output connectors, ensuring pins align with the header orientation. After connection, configure fan control in the motherboard BIOS/UEFI or controller software to manage fan curves and PWM response. Verify that fans are receiving power and responding to speed adjustments during system boot and in monitoring utilities.

Recommendations

Use this short 4 x 4‑pin PWM cable inside the case to minimize exposed wiring and avoid obstructing airflow. For best results, connect only PWM‑capable fans to preserve speed control functionality; mixing 3‑pin fans may limit control options. Ensure the combined current draw of connected fans does not exceed the rated output of the motherboard header or fan controller to prevent overload.
