Delock PWM Cable for CPU & Case Fan, 70 cm, 4-Pin

Delock PWM Cable for CPU & Case Fan – 70 cm 4-Pin Extension for Flexible Fan Power Routing

The Delock PWM extension cable is a 70 cm 4-pin power link for CPU and case fans, enabling flexible routing of fan connections within a PC chassis.

• 4-pin PWM connector on both ends ensures full speed control compatibility with modern fans
• 70 cm cable length provides ample reach for internal cable management without excess slack
• Compatible with standard PWM 4-pin fan headers — no adapter required
• Compact, low-profile design keeps the interior clean and airflow unobstructed

What sets the Delock PWM Cable apart

Unlike simple power splitters or non-PWM cables, this extension preserves the full 4-pin PWM signal path, so fan speed regulation remains fully functional. The neutral connector design fits standard ATX fan headers without forcing or modifying the connection.

Ideal for

PC builders and enthusiasts who need to extend a fan connection to a less accessible header on the motherboard, or who route fans in custom cases with non-standard header placement. Also suited for clean cable management in compact builds where direct fan-to-header reach is insufficient.

Application of the Delock PWM Cable

1. Connect the 4-pin PWM end to the motherboard fan header
2. Route the 70 cm cable to the desired fan position inside the case
3. Attach the second 4-pin PWM connector to the fan, ensuring a secure click
4. Verify in BIOS/UEFI that the fan is detected and PWM control is active
