By employing Cooler Master’s Fine Mesh technology, the MasterBox MB511 ARGB demonstrates a prowess for thermal performance and pairs it with premium lighting. Three ARGB fans are included in the box to complement hardware lighting while mesh ventilation on the front and top panel keeps gaming systems cool under pressure.  

With airflow potential and aesthetic customization maximized, high-demand gaming rigs can breathe easy in the MasterBox MB511 ARGB. 

Fine Mesh Front Panel

The Fine Mesh design on the front panel is proven, by reviewers and critics alike, to provide considerable airflow while simultaneously filtering out dust. Light also refracts and behaves uniquely to the Fine Mesh, creating a halo effect against the included ARGB fans. 

ARGB Lighting System

Three pre-installed ARGB fans can be managed by either the motherboard or an included controller, connected by the included splitter, to create a comprehensive ARGB lighting system. 

Tempered Glass Side Panel

Gaming hardware, cooling components, and the pure pride of the builder is shown in panoramic view through an edge-to-edge tempered glass side panel. 

Versatile Cooling Options

Support for up to seven 120mm fans and dual 360mm radiators on the top and front panel ensure that even the most extreme systems stay cool. 

ARGB Controller

The small ARGB Controller is a mini-sized controller that allows your Addressable RGB such as fans and LED strips to be powered and controlled even in PC systems without an A-RGB capable motherboard.

The controller comes with 14 lighting presets to make full use of the Addressable LEDs in the system and also allows to be completely switched off by long pressing its button.

It is also possible to attach any external 2pin button to it to be able to switch presets without having to open the system. For ease of use, Cooler Master allows the RESET button to be optionally connected to the controller and used as an external ARGB preset switch button.
