Reference Radeons RX 7900 XTX can reach temperatures of up to 110 °C
Tests of some graphics cards AMD Radeon RX 7900 XTX they show an interesting and not exactly pleasing feature. The differences between average and maximum (hotspot) temperatures are unusually high and this is mainly due to unusually high maximums. It turns out that cards with a reference cooler can reach temperatures up to about 110 °C, which are really very high values that do not bode well. The editors at HardwareLuxx, ComputerBase and TechPowerUp magazines took a closer look at the issue, and four Radeon RX 7900 XTX cards here showed a temperature hotspot of 109 to 110 °C. For the others it was only around 80-90 °C. These extremely hot Radeons all had one thing in common, they used a reference solution (two AMD cards, two PowerColor cards). What was interesting was that one paper had a difference of 53°C between the average and maximum temperature.
Now looking for the cause of the problem, it looks like a bad cooling solution that doesn’t sit perfectly on the GPU, and gravity is taking its toll. There was a test where the user had his computer turned vertically, meaning the card was horizontally in the board and the cooler was pointing down. In that case, the GPU easily reached 110 ° C at its peak. But when the computer was turned horizontally and the graphics were positioned vertically, the temperature of the hotspot dropped to only 75 ° C, a difference of 35 degrees. So if your Radeon RX 7900 is showing unusually high temperatures, try putting the case down and maybe your temperatures will drop dramatically. If the suspicions are confirmed, it will be interesting to see the next steps of AMD and card manufacturers with reference cooling.
