A custom Liquid Cooling Loop Kit or open-loop liquid cooling is a very similar concept to that of AIO cooling, but with some known differences. The term open in open-loop cooling refers to its compatible nature. There is no limit on the number of components that can be cooled through an open loop with suitable water blocks like adding graphics cards or radiators to the loop. It is upon the user to decide what tubing size, color, material and style they want. Also, there are chances that the color of the coolant can match the build but precisely, it depends on the user. Constructing a custom loop needs thought and planning in order to execute it properly. All the core components of the loop must be compatible along with that enough space is required to house the loop.
