Overview

A compact single-tower air cooler with four heatpipes and a 120mm PWM fan. Built for mainstream Intel and AMD sockets with addressable RGB lighting.

Tower Design and Heatpipes

The single-tower layout uses four 6mm heatpipes that make direct contact with the CPU lid. Heat moves quickly into the aluminum fin stack for efficient dissipation. The cooler stands 153.5mm tall and fits most mid-tower cases.

Fan Performance and Control

The included 120mm fan spins between 800 and 1800 RPM via 4-pin PWM. It delivers up to 77.07 m³/h of airflow and 1.86 mmH2O static pressure. Noise stays between 21.8 and 35.4 dB(A) across the speed range.

Socket Compatibility

Mounting hardware covers Intel LGA 115x, 1200, 1700, and 1851 plus AMD AM4 and AM5. The design supports processors up to a 225 W TDP rating for mainstream and enthusiast builds.

Lighting and Connections

Addressable RGB illumination runs through the fan rotor and top cover. A 3-pin 5V digital header connects to compatible motherboards for synchronization. The fan uses a standard 4-pin PWM connector for speed control.
