Fractal Design Lumen S28 RGB Aspect 14 RGB x2 AIO CPU Liquid/Water Cooler

Overview

The Fractal Design FD-W-L1-S2812 is an all-in-one liquid CPU cooler designed to maintain optimal temperatures for modern Intel and AMD processors. Featuring a 280 mm aluminum radiator paired with two 140 mm fans, it balances strong airflow with quiet operation, keeping noise levels below 35.5 dBA even at full fan speed. The cooler includes a pump running at 4000 RPM with a ceramic bearing for durability, and it comes pre-applied with thermal paste to simplify installation.

This cooler fits well in gaming PCs, creative workstations, and everyday systems that require reliable thermal management. Its flexible 400 mm braided nylon tubes allow versatile radiator placement in most mid-tower cases, while addressable RGB lighting on both the pump and fans adds customizable visual appeal.

Key features

• Pre-applied thermal paste eliminates the need for manual application, speeding up setup.
• Compatibility with Intel LGA 1700 and 1851 sockets, as well as AMD AM5, supports current and future CPU platforms.
• Two 140 mm fans with addressable RGB lighting provide effective cooling and customizable aesthetics.
• Quiet operation with noise levels under 35.5 dBA at maximum fan speed, suitable for focused work or streaming.
