Reservoir

pc

A reservoir in PC cooling systems is a component that stores additional coolant fluid.

expanded

In PC cooling systems, a reservoir acts as a storage unit for coolant fluid, allowing for top-ups and managing air bubbles in the cooling loop. It is essential for maintaining optimum cooling efficiency and longevity in custom liquid-cooling setups, providing a buffer against thermal expansion of the cooling fluid.

examples

The EK-RES X3 250 is a cylindrical reservoir with a capacity of 440 mL.

Commonly used in high-performance gaming PCs where custom liquid cooling is implemented to manage high thermal loads from overclocked CPUs or GPUs.

The Thermaltake Pacific PR22-D5 supports 300 mL, designed for integration with D5 pumps within custom open-loop cooling configurations.

Utilized in advanced PC builds where reliable fluid control and increased cooling efficiency are priorities, particularly in professional rendering or computation-intensive environments.
