The hot spot of GPU is 30 degrees Celsius higher than the core, and there is a problem of heat conduction paste in Radeon RX 7900 XTX Red Devils graphics card.
CTOnews.com May 18 news, according to the German science and technology media Igor's Lab test, found that PowerColor (PowerColor) Radeon RX 7900 XTX Red Devils graphics card has a heat dissipation problem.
In the evaluation of the Radeon RX 7900 XTX Red Devils graphics card, the media pointed out that there are obvious differences in the temperature and hot spot (hot spot) of the graphics card GPU.
At present, there are widespread differences in graphics cards. Take the Sapphire Radeon RX 7900 model as an example, the difference between the two is about 18 to 19 degrees Celsius.
In Shaoxun Radeon RX 7900 XTX Red Devils graphics card, this difference reached 30 degrees Celsius, in the actual operation there is a difference between 80 degrees Celsius and 110 degrees Celsius.
Igor's Lab then disassembled the graphics card and found that it was caused by the uneven distribution of thermal paste, and even in some places the GPU chip was not covered with thermal paste.
By adjusting the heat conduction paste, the temperature difference of the Radeon RX 7900 XTX Red Devils graphics card disappeared. The temperature of the graphics chip dropped from 80 degrees Celsius to 75 degrees Celsius, with the hottest spot between 93 and 95 degrees Celsius.
Shaoxing subsequently admitted the problem, saying that there was a technical error in the process of assembling some graphics cards. The company promised to replace the heat conduction paste on the assembly line and consider changing the installation process of the cooling system.
It is not clear whether only Radeon RX 7900 XTX Red Devils is affected.
The official statement of the CTOnews.com translator is as follows:
We have identified the cause of the problem, which is caused by production, and after inspection, it is confirmed that only a small number of graphics cards are affected.
We are already replacing the heat conduction paste used in assembling the accelerator. We are trying to solve this problem as soon as possible.
