Which component is used to attach to devices to help remove heat through convection?

The component that is primarily used to attach to devices to help remove heat through convection is the radiator. In the context of a cooling system, such as liquid cooling in computers, the radiator plays a critical role in dissipating heat.

When liquid coolant absorbs heat from components like the CPU or GPU, it then flows into the radiator. Here, the heated liquid passes through a series of tubes and is exposed to air, which allows heat to transfer from the liquid to the air through convection. The design of a radiator, with its fins and surface area, enhances this heat transfer, leading to more efficient cooling of the components.

While the water block (commonly referred to as the water block/water bracket) does connect to the CPUs and GPUs and is responsible for absorbing heat from them, it does not remove heat from the system; rather, its function is to transfer the heat to the coolant. The coolant then moves the heat to the radiator, where it is effectively dissipated.

The pump is crucial for circulating the coolant throughout the system, and the liquid reservoir serves to hold an adequate amount of coolant, but neither of these components are directly responsible for heat removal through convection. Hence, the radiator is the correct choice, as it is specifically designed
