## Long description

The EK-Quantum Volume³ FLT reservoir is a flat-style acrylic reservoir designed for PC liquid cooling loops. It offers a transparent body, integrated Addressable D-RGB LED strip concealed under a removable black anodized aluminum cover, and multiple G1/4" connection ports for flexible loop routing. The reservoir is available in several lengths to suit different build layouts and includes 140 mm fan-pattern mounting holes to fit common case locations without additional drilling.
Advantages
The flat design and standard 140 mm fan mounting pattern increase installation flexibility inside modern PC cases. Six G1/4" ports allow varied inlet/outlet configurations to optimize loop topology. The unit is made from precision-machined acrylic with a high-quality EPDM o-ring seal for reliable leak protection, and the removable cover enables easy access to the Addressable D-RGB strip for service or replacement. Included steel L-shaped mounting plates and M4-threaded mounting holes simplify secure attachment.
