Two 120mm SickleFlow fans each provide an airflow of up to 62 CFM at a static pressure of 2.5 mmH₂O, mounted on a 27mm thick aluminum radiator for enhanced heat dissipation. Built with a copper cooling plate and anti-leak technology, the cooling system ensures reliable continuous operation. The LCD display supports custom images and animations via Cooler Master software for personalized system monitoring. Installation is made easier with pre-applied thermal paste and universal mounting brackets. The cooler's dimensions are 277mm x 119.6mm x 27mm for the radiator, with a tube length of 400mm.
