• WHAT A COOL(ING) BLOCK
• Obsession with details
• The cooling block of Silent Loop 3 420mm is undisputed. The explanation may look complicated, but we owe it to our most loyal fans and all the enthusiasts out there: The cooling block boasts a 1,800 mm2 fin area, which is an increase of up to 2x compared to many other AiO's in this class. This greatly improves heat transfer and makes sure to cover all hot spots on the CPU. The large fin area could only be achieved by a specially developed screwless design for attaching the heat plate. The internal design of the flow path takes care that all areas are flowed to evenly to achieve high performance regardless of the CPU platform.
• SUPERIOR PUMP DESIGN
• Enjoy the silence
• A powerful PWM pump with 3-chamber design ensures the very high-performance of Silent Loop 3 420mm and is whisper-quiet at the same time. The second of its 3 chambers acts as a reservoir and offers enough space for the coolant to spread out and thus reduces turbulences before the liquid leaves the pump unit. In combination with the 6-pole 3-phase motor this results in a smooth and consequently silent operation.
