Clear Cylindrical Water Cooling Reservoir Tank for PC and Electric Motorcycle DIY Systems

This transparent cylindrical water cooling reservoir serves as an essential fluid management component in custom liquid cooling setups for both computer hardware and electric motorcycle applications. Measuring 155mm in length with a consistent 50mm diameter, its clear design allows builders to visually monitor coolant levels, check for air bubbles, and observe fluid condition without disassembly. Available in four distinct colour options—red, green, blue, or white—the reservoir offers aesthetic coordination possibilities while maintaining its primary functional purpose as an expansion chamber and air trap in closed-loop cooling systems. The optional LED lighting version provides additional visual enhancement for showcase builds where component visibility matters.

Features and Construction

Constructed from multiple engineered materials, this reservoir combines visual clarity with functional durability for demanding cooling applications. The transparent cylindrical form factor prioritises practicality while offering flexibility in mounting orientations and system integration.

Material and Build

The reservoir utilises three primary materials: POM (polyoxymethylene), acrylic, and engineering plastic. POM contributes dimensional stability and low friction properties, helping maintain seal integrity under temperature variations. Acrylic provides the visual transparency that enables fluid monitoring, while engineering plastic offers structural strength and resistance to chemical degradation from common water cooling additives. This material combination addresses the specific requirements of liquid cooling systems where contact with various coolant formulations occurs regularly.

Size and Practical Fit

With dimensions of 155mm length and 50mm diameter, this reservoir offers a standardised form factor compatible with many PC cases and electric motorcycle frame configurations. The cylindrical shape allows for flexible mounting options including vertical, horizontal, or angled orientations depending on available space constraints. The consistent 50mm diameter facilitates secure mounting with standard reservoir brackets and ensures predictable fluid dynamics within the cooling loop. Builders can incorporate this reservoir into systems where approximately 300ml of additional coolant capacity is beneficial for thermal stability.

Uses and Placement

Designed for versatility across different cooling applications, this reservoir supports both computer and electric vehicle cooling needs. Its clear construction and chemical-resistant materials make it suitable for various DIY projects beyond its primary intended uses.

Event or Professional Use

For professional PC building or competitive overclocking events, the clear reservoir allows judges and spectators to verify proper coolant flow and absence of air bubbles in competition systems. In electric motorcycle applications, professional builders can incorporate the reservoir into custom cooling solutions for high-performance electric drivetrains where thermal management is critical. The optional LED lighting version enhances visibility in demonstration environments or showcase builds where aesthetic presentation matters alongside functional performance.

Everyday Home Use

Home PC enthusiasts can utilise this reservoir in custom water-cooled gaming or workstation computers where visual monitoring of coolant condition provides peace of mind during extended operation. For DIY electric vehicle projects, the reservoir offers a reliable fluid expansion chamber that helps maintain consistent coolant volume as temperatures fluctuate during normal riding conditions. The clear design allows hobbyists to check fluid levels quickly without complex disassembly procedures, supporting easier maintenance routines for home-built systems.

Benefits and Buying Value

Beyond its basic function as a coolant container, this reservoir provides practical advantages through material choices and design considerations. The combination of visual monitoring capability with chemical-resistant construction addresses common concerns in liquid cooling system maintenance.

Reuse and Low Maintenance

The chemical-resistant materials support reuse across multiple coolant changes and system rebuilds. POM's dimensional stability helps maintain seal integrity through thermal cycles, reducing potential leakage points over time. The manufacturer's specific warning against alcohol-containing liquids provides clear guidance for safe cleaning methods that preserve material properties. With proper care following the provided guidelines, the reservoir can serve as a long-term component within evolving cooling systems as enthusiasts upgrade other components around it.

Why Choose This Product

This reservoir offers a balanced combination of visual clarity for monitoring, chemical resistance for durability, and standardised dimensions for compatibility. The availability in four colours with optional lighting provides customisation options without compromising the primary functional requirements of a cooling reservoir. Builders working across both PC and electric vehicle applications benefit from a component that serves similar functions in different contexts, potentially allowing for standardised maintenance procedures. The clear material warnings regarding alcohol use demonstrate manufacturer attention to material compatibility concerns that might otherwise lead to component failure.
