Feature
CL660 rethinks case design for the liquid-cooling era. By physically separating thermal zones and airflow paths, it prevents heat buildup and cross-interference that conventional layouts can’t avoid. It also includes two reverse-blade fans at the bottom, completing a build that balances cooling efficiency and modern aesthetics.

SPLIT FOR PERFECT FLOW
CL660 keeps things cooler with a modular split-chamber layout. It provides a dedicated zone for your radiator, creating separate airflow paths for heat-generating components and letting the whole system run at its best.
BALANCE IN LAYERS
A raised top chamber redefines the overall silhouette while keeping space organized. Vertical grille bars at the front provide natural ventilation and create visual rhythm, with real wood adding an organic finish to the clean, modern aesthetic.
BUILT-IN ATMOSPHERE
Pre-installed and smartly recessed, the dual FL12R SE fans at the bottom pull in fresh air and illuminate your build with a vivid glow—without taking up visual space.
WIDE COOLING FLEXIBILITY
Maximize your cooling potential with support for 360mm AIOs and up to eight 120mm fans in total. Three 120mm fans or two 140mm fans can be mounted above the radiator in push-pull configuration (fan–radiator–fan).
