Reservoir for custom PC liquid cooling Singularity Protium 200mm acrylic – SC-PROTIUM-M-BF

Singularity Protium 200mm is an acrylic cylindrical reservoir engineered for custom PC liquid cooling loops. Designed to store and feed coolant while providing a clear visual of fluid level, this reservoir supports common loop topologies and offers a compact vertical footprint suitable for cases and custom mounts. The acrylic construction balances clarity and mechanical rigidity to display coolant colour and circulation without obstructing flow.

Advantages

The transparent acrylic tube provides an unobstructed view of coolant level and flow, aiding monitoring and leak detection. Precision-machined end caps and port openings ensure reliable sealing and compatibility with threaded fittings. Its 200 mm height increases coolant volume for improved thermal buffering and flow stability compared with smaller reservoirs, while remaining compact enough for many chassis and custom mounting solutions.

Suitable for

• Custom water-cooled gaming and workstation PCs
• Upgrades where increased coolant capacity and visible flow are desired
• Builds requiring a vertical reservoir mount with clear coolant monitoring

Key specifications

• Material: Acrylic reservoir tube with metal or machined end caps
• Orientation: Vertical cylindrical form factor, 200 mm usable height
• Port compatibility: Threaded ports designed for standard liquid cooling fittings
• Function: Coolant storage and feed with visual level indication
• Mounting: Designed for case or custom mounts that support cylindrical reservoirs

How to use

Install the reservoir in a vertical position within the case or on a custom bracket, securing the end caps and ensuring port threads are clean. Connect inlet and outlet fittings to integrate the reservoir into the loop, observing correct flow direction and orientation. Fill the loop with coolant through the fill port, bleed air using standard loop-bleeding techniques, and check all seals and fittings for tightness before powering the system. Monitor coolant level and clarity periodically and top up as needed.

Usage recommendations

Use compatible threaded fittings and corrosion-resistant tubing; avoid exposing acrylic to aggressive chemicals or abrasive cleaners. When mounting, ensure the reservoir is supported at both ends if possible to reduce stress on fittings and seals. For long-term maintenance, inspect seals and replace coolant according to your cooling system maintenance schedule.
