The DeepCool CL6600 is an innovative compact ATX case designed specifically for the liquid-cooling era. It features a unique modular split-chamber layout called HyperSplit that physically separates the thermal zones and airflow paths, preventing heat accumulation and thermal crossover between the CPU radiator chamber and the GPU/main chamber. This advanced design ensures superior cooling performance and helps maintain optimal temperatures for your components.

Equipped with a pre-installed 360mm ARGB liquid cooler with triple FDB radiator fans and dual 120mm reverse-blade ARGB fans mounted on a pull-out bottom bracket to maximize GPU cooling, the CL6600 offers immediate and efficient thermal management. Its short-tube routing design results in a cleaner build with less clutter around the CPU socket.

Supporting Mini-ITX, Micro-ATX, and ATX motherboards (including back-connected layouts), this case provides versatile compatibility. The front I/O panel includes two USB 3.0 ports, one USB Gen2 Type-C port, and a combined audio/mic jack for convenient connectivity.

The CL6600 accommodates GPUs up to 413 mm in length (or 388 mm when the front fan is installed) and CPU coolers up to 175 mm in height. It uses a front-mounted PSU layout supporting ATX PS2, SFX, and SFX-L power supplies with a maximum length of 160 mm, featuring a separate exhaust path to keep airflow from interfering with other components.

Additional features include tool-free panels, a pop-out headset hook, pull-out dust filters on intakes and exhausts for easy maintenance, and a stylish real-wood exterior accent for a premium aesthetic. With extensive fan and radiator support—including up to eight fans in various locations—it enables excellent cooling customization for high-performance PC builds.
