"The CASTLE 280EX is equipped with patented Anti-Leak Technology that helps regulate pressure buildup to significantly improve operational safety and prevent leakage. Learn more about Anti-leak Tech Inside. A stronger 3-phase motor provides higher cooling performance with an increased flow rate while keeping noise levels low. Designed from the inside out, the new dual-chamber pump features an optimized flow route for better heat exchange. With 25% more skived fins on the copper cold plate, the larger surface area effectively dissipates heat. Specially tuned Deepcool TF140 S fans deliver the extreme cooling performance for AIO liquid coolers by maximizing both static pressure and airflow. Upside down logo?
