LovingCool LC-400B ARGB CPU Air Cooler — Black

The LovingCool LC-400B RGB CPU Air Cooler is a universal 120 mm CPU heatsink cooler designed for broad Intel and AMD compatibility, using a hydraulic-bearing fan, aluminum/copper construction, and 5V ARGB lighting for a more modern RGB build look. It follows the same general cooling profile as the LC-400A, but the lighting specification is updated to 5V ARGB for motherboard synchronization, making it a better fit for current RGB ecosystems. With 12 V operation, a 4-pin power connection, and up to 1800 RPM fan speed, it remains a simple, practical air cooler for mainstream desktop systems.

Key Features

• Universal socket support for a wide range of Intel and AMD platforms, including LGA 115x, 1200, 1366, 1700, AM2, AM3, AM4, AM5, FM1, FM2, and older sockets.

• 120 mm fan diameter with a 4-pin power connection for standard motherboard control.

• Hydraulic bearing design for smoother operation and better long-term reliability.

• 5V ARGB lighting for motherboard sync compatibility and modern RGB builds.

• Aluminum, plastic, and copper construction for balanced cooling and durability.

• Maximum airflow around 55 CFM for general CPU cooling performance.

• Maximum fan speed of 1800 RPM on 12 V power.

• Black finish for a clean, neutral build match.

Technical Specifications

The LC-400B is best for users who want a broad-compatibility RGB CPU air cooler for mainstream desktops, office upgrades, or entry-level gaming builds, but with 5V ARGB synchronization instead of basic multicolor lighting. Its main strengths are universal socket support, a 120 mm fan, hydraulic bearing design, and simple 4-pin 12 V cooling in a straightforward heatsink format.
