Ruth's sister Manual Chassis Fan Speed Controller 12V internal power cable

SKU CH-6ZN5-WS8A3

Adjusts chassis fan speed manually across three levels using a 12V internal power cable

  • Manual 3-level fan speed adjustment for precise cooling control
  • 12V power supply compatibility ensures stable operation
  • Internal power cable design integrates cleanly inside the chassis
  • Fan hub function manages multiple cooling fans from one controller

Manual Fan Speed Controller

This internal power cable adds a three-level manual switch to adjust chassis fan speeds directly. It suits builders who want simple, hardware-based control over cooling noise without software or BIOS configuration. The unit draws 12 V power from the PSU and distributes it to connected fans. It is a compact add-on for custom cooling loops or air-cooled cases.

Three-level speed adjustment

The single specification that decides fit is the three-level manual adjustment, which lets you select low, medium or high fan voltage with a physical toggle. Buyers who need PWM signalling, automatic temperature curves or more than three discrete steps cannot use this controller. It also requires a free 12 V power connector from the supply, so systems without spare leads will need a splitter or alternative hub.

Questions about this item

What does the 12V rating mean for my fan setup?

The controller draws 12 V from the power supply and distributes it to connected fans so they can be slowed or sped up manually.

How does the three-level switch affect the fan header limits?

Each of the three switch positions sets a fixed voltage step that caps the maximum speed any attached fan can reach.
