Reservoir Singularity Computers Protium 200mm Acrylic Black — PC liquid cooling reservoir, 200 mm, acrylic, black finish

The Reservoir Singularity Computers Protium 200mm Acrylic Black is a cylindrical 200 mm acrylic liquid cooling reservoir designed for custom PC water-cooling loops. The transparent acrylic tube provides a clear view of coolant level and flow while the black-finish end caps and mounting hardware deliver a compact, vertically oriented reservoir solution for system builds where space and visual integration matter. It is intended for closed-loop circulation with fittings and tubing, offering reliable coolant storage and straightforward monitoring during operation and maintenance.

Advantages

The acrylic construction combines good optical clarity with lightweight durability, enabling easy visual inspection of coolant condition and level. Its 200 mm length offers sufficient reservoir volume for many compact and mid-size builds while keeping a small footprint. The black finish on end caps and mounting components helps the reservoir blend into darker-themed systems and reduces visible glare from internal lighting. The design supports common G1/4 or standard liquid-cooling fittings (verify compatibility with your components) for straightforward integration into existing loops.

Suitable for

• Custom PC water-cooling loops requiring a vertical reservoir with compact dimensions
• Systems where coolant visibility and level monitoring are needed
• Builds with black or dark-themed components for visual consistency
• Maintenance routines that benefit from an easily accessible reservoir

Key specifications

• Reservoir type: cylindrical acrylic tube, vertical orientation
• Length: 200 mm usable tube height
• Material: clear acrylic tube with black-finish end caps and mounting hardware
• Connection: compatible with standard liquid-cooling fittings and tubing (verify thread type and size before installation)
• Mounting: vertical mounting hardware included for case or bracket installation
• Visibility: transparent body for coolant level and flow observation

How to use

Mount the Protium reservoir vertically in a suitable location inside the case or on a compatible bracket using the supplied mounting hardware. Install appropriate fittings into the reservoir end ports and connect inlet and outlet tubing to form the loop; ensure thread types and sealing are compatible and tightened to specification. Fill the loop with a recommended coolant, purge air by running the pump in short cycles while topping up the reservoir, and verify leak-free operation before prolonged use. Periodically inspect the reservoir for coolant level, discoloration, and secure fittings as part of routine maintenance.

Usage recommendations

Use coolants and additives that are compatible with acrylic and other loop materials; avoid aggressive chemicals that can cloud or degrade acrylic. When integrating with a pump and other loop components, confirm fitting thread sizes and tubing diameters to ensure proper sealing and flow. Regular visual checks and scheduled coolant replacement will help maintain loop performance and component longevity.
