SKU CH-V6EX-0MVS7

A 4020 internal power cable with dual ball bearing for silent north/south bridge cooling

  • 4020 model fits tight internal spaces efficiently
  • 412 rating indicates reliable power delivery performance

DELTA EFB0412MD internal cable

The DELTA EFB0412MD is a 4020 internal power cable designed for North and South bridge cooling applications. It uses a dual ball bearing construction to deliver quiet operation inside the chassis. The cable suits builders who need a compact 412 form factor for targeted motherboard component airflow.

Upgrades from basic cooling cables

This cable replaces standard internal power leads that lack the dual ball bearing design for silent performance. The jump is worth it when a builder requires a dedicated 4020 connection for chipset cooling without adding audible fan noise. It is not for systems that use larger fan headers or require different connector pinouts.
