A reservoir and a distroplate are both components used in custom computer water cooling systems, but they have different functions.
A reservoir serves primarily as a storage and venting container for the cooling water. It can come in different shapes and sizes and is often used in combination with a pump. The reservoir allows the system to be filled and bled and serves as an additional volume for the cooling water.
A distroplate, on the other hand, has a distribution function. It is a special component designed to efficiently distribute cooling water to various components such as CPU, GPU and radiators. The Distroplate acts as a central connection unit and can contain various fittings and ports to ensure the smooth flow of cooling water and create an aesthetically pleasing connection.
Overall, the reservoir serves to store and vent the cooling water, while the distroplate serves as a distributor to evenly distribute the cooling water to various components.
