Owners of new AMD Radeon RX 7900 video cards have encountered a problem – their devices may overheat in some cases. So, when the device is positioned vertically and horizontally, the temperature readings could differ significantly.
To determine the cause of the problem, user Der8auer tested four video cards with different installation options. He tested each specimen under load for 10 minutes. At the same time, it turned out that when installed horizontally, video cards heat up more and faster. In addition, in a horizontal orientation, the cooling system of the devices operates at higher fan speeds and produces more noise. For example, when installed horizontally, the fan speed was much higher at 2000 rpm compared to 1700-1800 rpm in vertical mode.
In the process of testing, Der8auer conducted a number of additional experiments. He made a special stand to find out if less weight and gravity could be the reason for the higher temperatures observed in the horizontal mode. He also modified the cooling system to reduce the gap between the GPU and the cooler. All these manipulations did not solve the problem and did not lead to a decrease in temperature.

In addition, Der8auer tested how video cards behave if their orientation is changed during high load. It turned out that turning the device from a vertical orientation to a horizontal one leads to an increase in GPU temperature. Interestingly, returning the video card to its original position does not lead to a reverse decrease in temperature.
Der8auer believes that this behavior of video cards is most likely the result of a problem in the design of the evaporation chamber, which leads to improper circulation of liquid in it.
