The graphics processing unit (GPU) of a computer’s graphics card is cooled using fans called graphics card cooling devices. On a computer, the GPU renders pictures and graphics, and while it works, it produces a lot of heat. Overheating of the GPU can cause performance problems or even hardware breakdown. Typically, graphics card cooling fans are installed on the graphics card or a heatsink that is connected to the GPU. In order to assist cool down the hot GPU, they function by pulling in cool air from outside the casing. While some cooling fans for graphics cards are made to be quiet and low-profile, others are made to be more potent and effective at cooling. In general, graphics card cooling fans are a crucial part of any computer system that uses a dedicated graphics card since they ensure that the GPU is working within its ideal temperature range and guard against overheating.
