## Long description

The Alphacool 15394 Acrylic Black Transparent reservoir is a tubular coolant reservoir designed for custom PC liquid cooling loops. Constructed from durable acrylic, it combines a black finish with transparent sections to allow visual monitoring of coolant level and flow. The reservoir has a tube diameter of 7.65 cm and a length of 25.1 cm, and its construction yields a net weight of approximately 621 g. Integrated RGB lighting operates at 5 V to add controlled illumination to the cooling loop while preserving a minimalist appearance.
Advantages
This reservoir provides reliable coolant storage with a rigid acrylic body that resists deformation and provides clear visibility into fluid condition. The black and transparent design balances concealment and visibility, helping to hide mounting hardware while keeping the coolant level observable. Built-in 5 V RGB lighting improves system aesthetics and allows synchronization with compatible controllers without affecting coolant performance.
Suitable for
Custom PC water-cooling loops in desktop gaming or workstation systems
Systems requiring visible coolant monitoring and level checking
Builds where aesthetic lighting and a black/transparent finish are desired

Length: 25.1 cm

How to use
Install the reservoir in a suitable position inside the case or on a compatible mounting bracket so that inlet and outlet ports align with the loop routing. Fill the reservoir with appropriate coolant following the coolant manufacturer's instructions, then bleed air from the loop by running the pump at low speed until all air is expelled. Connect the 5 V RGB header to a compatible controller or motherboard RGB output to enable lighting control. Periodically check the coolant level and inspect for any signs of leaks or discoloration.
Usage recommendations
Use coolant and cleaning agents that are compatible with acrylic to avoid surface damage. Avoid exposure to strong solvents and abrasive cleaners. For optimal performance, maintain regular coolant replacement intervals, verify secure fittings, and ensure the RGB header voltage matches the controller specification.
