RTX 3080 Graphics Card Ran 14°C Cooler Next to a Side Air Intake
A computer enthusiast known as “TrashBench” tested an “RTX 3080” graphics card in different positions inside a desktop computer case. In the best configuration, the temperature fell by 14°C at the graphics card’s hottest point and by 3.3°C on the CPU. In another configuration, the reduction on the graphics card reached 19°C, but the CPU ran hotter.
For comparison, a conventional configuration was tested first. An AIO with a 360 mm radiator, meaning a closed-loop liquid cooling system, was selected to cool the CPU. The 3-fan “RTX 3080” graphics card was also installed in the standard PCIe slot. To place a constant load on the system, the “3DMark Time Spy” loop and the “7-Zip” program’s built-in benchmark were run simultaneously. The speeds of all system fans were left unchanged to ensure that the results could be compared accurately. The graphics card was then tested vertically at the bottom and side of the case. Turning the card in different directions, as well as positioning it in front of and behind the 3 case fans on the side, was tested separately. The fans on the CPU’s liquid-cooling radiator were also operated in different directions to draw air in and expel it. Some configurations cooled the graphics card better, while others primarily provided better cooling for the CPU. The final configuration combined the best results from the previous tests. The graphics card was positioned vertically in front of the side air intake. The CPU radiator was also kept in the conventional position, exhausting hot air from the case. The graphics card ran 14°C cooler and the CPU ran 3.3°C cooler. Testing this configuration requires a PCIe riser cable that connects the graphics card outside the main PCIe slot.
