Reservoir for liquid cooling, Singularity Computers Protium 100mm Acetyl (silver black)

Singularity Computers Protium 100mm Acetyl (silver black) is a compact cylindrical reservoir designed for custom PC liquid cooling loops. Made from acetyl material, the 100 mm body provides coolant storage and a clear feed point for pumps and radiators while maintaining a neutral silver‑black appearance that integrates with a wide range of system styles. The reservoir supports standard fittings and mounting options used in DIY water cooling builds and is intended for use in custom loop systems where compact size and durable material are required.

Advantages

The acetyl construction offers chemical resistance and dimensional stability suitable for long‑term coolant contact. Its 100 mm height gives a small footprint that fits many mid‑tower and compact cases while still providing sufficient coolant capacity for pump priming and system maintenance. The neutral silver‑black finish reduces visual contrast with other components, making the reservoir suitable for both subtle and modular aesthetic builds.

Suitable for

• Custom PC liquid cooling loops in mid‑tower and compact cases
• Pump priming and steady coolant supply to radiators and blocks
• System maintenance tasks such as filling, draining and leak testing
• Builds requiring a compact, neutral‑finish reservoir for aesthetic coherence

Key specifications

• Material: acetyl (delrin/plastic engineering material)
• Form factor: cylindrical reservoir, 100 mm height
• Finish: silver‑black neutral appearance
• Compatibility: standard liquid cooling fittings and tubing sizes (user to verify specific fitting thread and tubing diameter)
• Function: coolant containment and feed for pumps and radiators in custom loops

How to use

Install the reservoir in a suitable location within the case where the inlet and outlet lines can be routed without strain. Connect the reservoir to the pump inlet and to the rest of the loop using compatible fittings and tubing, ensuring all connections are tightened to the manufacturer’s torque recommendations. Fill the loop with the chosen coolant, perform pump‑only cycles to remove air and verify flow, then complete leak testing before normal operation. Periodically inspect for signs of wear, discoloration, or leaks and service the loop as needed.

Usage recommendations

Use compatible coolants and corrosion inhibitors recommended for plastic reservoirs, verify fitting thread types and tubing diameters prior to installation, and perform a full leak test after assembly. When placing the reservoir, allow easy access for filling and maintenance and avoid exposing acetyl components to aggressive chemical cleaners or prolonged direct sunlight.
