Overview

This all-in-one liquid cooler uses a 420mm radiator and three 140mm fans to handle high thermal loads. It fits modern Intel and AMD platforms and includes addressable RGB lighting.

Cooling Performance

The 420mm radiator provides a large surface area for heat exchange. Three 140mm PWM fans move air across the fins while the pump circulates coolant through pre-assembled tubing. This combination handles overclocked CPUs and sustained workloads.

VRM Fan and Installation

A dedicated fan inside the pump housing blows air toward the motherboard voltage regulators. This lowers VRM temperatures during heavy loads. The unit arrives with hoses and pump pre-connected, reducing build time.

Lighting and Control

Addressable RGB LEDs are located on the pump cap and all three fans. They connect via a single 3-pin 5V digital RGB header and synchronize with motherboard software from major vendors.

Compatibility and Dimensions

The cooler supports Intel LGA1700, LGA1851 and AMD AM4, AM5 sockets. The radiator measures 458mm wide, 138mm deep, and 65mm thick with fans installed. Tube length is 500mm for flexible routing in large cases.
