The DeepCool LE300 Marrs is a 120mm all-in-one liquid CPU cooler designed for reliable thermal management with a thermal design power rating of 180W. It is equipped with a high-density aluminum radiator and a powerful PWM fan to effectively dissipate heat from the processor. A solid copper cold plate ensures direct thermal transfer, and the unit incorporates DeepCool's Anti-Leak Technology, which helps automatically balance pressure within the closed loop for operational safety and longevity.
The system's 120mm fan is PWM-controlled, operating between 500 and 2250 RPM to balance cooling performance with acoustics. It generates high static pressure and airflow, which is necessary for moving air effectively through the radiator fins. The pump maintains a constant speed of 2400 RPM for steady coolant circulation, and the water block is illuminated by a fixed Marrs green LED. Its included mounting hardware provides support for a wide array of modern Intel and AMD sockets.
