5V 3-pin ADD-RGB

Equipped with a mirror finish, immersive lighting and infinite visual effects, the CASTLE 280EX inherits its familiar yet fabulous appearance. Its Addressable RGB lighting is adjustable through the 5V motherboard SYNC function or through an included controller.

*Also controllable by motherboard 12V SYNC function via an RGB converter (not included).


With more rounded corners implemented into its design, the upgraded double chamber has optimized flow route and increased heat exchange efficiency. This also contributes to reduction of operation noise and energy loss.


With 25% more skived fins on the copper cold plate, the larger surface area effectively dissipates heat.

With its small size, it can be installed in any direction.
