摘要

The influence of temperature on the performance of a graphics processing unit (GPU) used in the MSI GeForce RTX 3080 video card has been studied. The importance of effective management of the processor's thermal parameters and of the selection of optimal solutions for its cooling is shown, which is critical for the stable operation of video cards. It has been found experimentally that the use of fans providing air intake allows reducing the GPU temperature by 10–15°C and increasing its performance by 15–20% under high load conditions. In turn, the use of fans aimed at air exhaust improves processor cooling but with a lesser effect, adding only 5–10% to its performance. The results of video card modeling are presented, showing that high processor temperature significantly reduces its performance, starting with throttling at 80°C, which leads to a decrease in processor performance by 10–30% depending on the level of its overheating.
