Key Features

[Better Heat Dissipation] The cooler is mainly composed of a twin-tower body with symmetrical mecha-shaped fins + pure copper six heatpipes + high-performance dual fans. The pure copper base senses the CPU temperature, then disperses the temperature from the heatpipes to the large-area aluminium fins, and then the 1500RPM high-volume dual fans dissipate the heat to achieve a good heat dissipation effect.
[Optimised Body Details] The body of the radiator features a white nano-painted layer, a combination of white-painted buckled FIN aluminium fins and heatpipes, and a precision reflow soldered micro-engraved copper base to form the cpu double towers cooler.
[158mm Height] The height of the cpu cooler is 158mm, which is suitable for large and medium-sized chassis, and is compatible with the installation of high-marshal memory and graphics cards, and the all-aluminium fins of the main body can bring the maximum cooling area.
