Product Overview
The LIAN LI LANCOOL III RGB is designed for high-performance gaming and enthusiast PC builds, combining excellent airflow with a spacious and highly modular interior. Its fine-mesh front design provides unrestricted airflow to high-end components, while tempered-glass panels on both sides and hinged lower panels provide easy access to the system.
The RGB Black version comes factory-equipped with 3 × 140mm ARGB PWM intake fans at the front and 1 × 140mm PWM exhaust fan at the rear. The front ARGB fans operate from 300–1650 RPM and are rated for up to 83.5 CFM each, providing strong cooling performance straight out of the box.
Cooling expandability is extensive. The chassis supports 3 × 120mm or 3 × 140mm fans at both the front and top, a 120mm/140mm rear fan, and 3 × 120mm fans above the PSU chamber, for a maximum of 10 fans.
For liquid cooling, the LANCOOL III supports 360mm or 420mm radiators at both the front and top, plus a 360mm radiator above the PSU chamber. LIAN LI specifically highlights support for configurations with up to a 420mm radiator or as many as three 360mm radiators.
The spacious interior supports E-ATX motherboards up to 280mm wide, along with ATX, Micro-ATX, and Mini-ITX. Component clearance includes graphics cards up to 435mm, CPU air coolers up to 187mm, and ATX power supplies under 220mm.
Storage flexibility is another major strength, with mounting locations for up to 12 storage drives depending on configuration. The chassis also incorporates LIAN LI's upgraded cable-management system to keep complex high-end builds clean and organized.
