Reservoir Alphacool 15075 Acrylic Black Transparent 120mm

The Alphacool 15075 Acrylic Black Transparent 120mm reservoir is a compact component for custom PC liquid cooling loops. Constructed from durable acrylic, the reservoir combines a black outer finish with transparent viewing panels to allow fluid level monitoring while maintaining a discreet appearance. Its footprint measures 120mm by 120mm with a height of 50mm, providing space-saving integration in systems with limited internal clearance. The reservoir includes 5V-enabled RGB lighting for visual customization and is intended for use as part of closed-loop or custom open-loop cooling configurations.

Advantages

The acrylic construction offers scratch-resistant clarity and reliable physical stability under typical system conditions. The black transparent styling conceals internal tubing while permitting easy visual inspection of coolant levels. Compact dimensions allow installation in tighter case layouts where larger reservoirs would not fit. Built-in 5V RGB lighting adds adjustable illumination without requiring separate lighting accessories, simplifying aesthetic coordination with other 5V RGB components.
