AMD 7900 XTX graphics card heat problem is probably related to the vapor chamber

Roman Hartung (a.k.a. der8auer), who is very fond of overclocking hardware, says he may have found the root cause of the AMD Radeon RX 7900 XTX graphics card overheating problem. Apparently, AMD’s flagship desktop class uses a defective vapor chamber.

Overclocking in the world of hardware means increasing the clock speed (frequency) of components. Hardware components have a certain frequency limit by default, but this limit can be exceeded with overclocking.

to the writing of Toms Hardover, Hartung purchased four Radeon RX 7900 XTX reference graphics cards to root out a hot problem. He says that the horizontal arrangement of the steam chamber has a positive effect on the performance of the heat distribution system and has caused the temperature of the graphics card to decrease by 20 degrees Celsius; But unfortunately, one minute after the start of the test, a hot problem can be seen in the AMD graphics card.

Apparently, the vapor chamber used in RX 7900 XTX has a structural defect. The defect of the steam chamber is not exactly a problem, perhaps the main problem is related to the raw materials used in it. Apparently, the liquid inside the vapor chamber does not flow well after condensing. The reason for the problem may be the lack of sufficient pressure inside the steam chamber or the lack of liquid used in it.

AMD has said it is aware of the overheating issue with a number of RX 7900 XTX graphics cards, but has yet to provide a solution. Apparently, this issue doesn’t affect all new graphics, but the number of users reporting the RX 7900 XTX running hot is quite high.

RX 7900 XTX is AMD’s new flagship and it was produced with the aim of gaming experience in 4K resolution. The RX 7900 XTX performs up to 1.7 times faster than the previous generation flagship at 4K resolution. This high-end graphics card has 96 computing units (CU), a clock speed of 2.3 GHz and 24 GB of GDDR6 memory with a 384-bit bus.
