Overview

A white 420mm all-in-one liquid cooler with three 140mm fans, an integrated VRM fan, and addressable RGB lighting. Compatible with current Intel and AMD desktop sockets.

Design and Build

The radiator, fan frames, and rotors share an all-white finish. Three 140mm fans mount to a 420mm aluminum radiator with copper cold plate. Total radiator height with fans is 65mm. Tubing measures 500mm for routing flexibility in large cases.

Cooling Performance

The large surface area and three PWM fans deliver high airflow for demanding CPUs. A dedicated VRM fan blows across motherboard voltage regulators to improve stability under heavy loads. Pump speed is PWM controlled via a 4-pin header.

Lighting and Control

Addressable RGB LEDs on the fans and pump housing connect through a 3-pin 5V digital RGB header. Effects, colors, and brightness are managed through motherboard software or Arctic's Signal RGB application.

Compatibility and Contents

Mounting hardware covers Intel LGA1700 and LGA1851 plus AMD AM4 and AM5 sockets. The box includes the pre-assembled AIO unit with three 140mm fans already installed.
