AMD's RX 7900 series graphics cards are really ill-fated. Performance and power efficiency are far from the rival of the RTX 40 series.
RX 7900 series public version soon after the market was found to have abnormal high temperature problems, Hot Spot temperature up to 110℃, later found to be caused by insufficient heat pipe cold night, the error is quite low-level.
Now it seems that the non-public version is not very concerned, Igor's Lab found that the top flagship RX 7900 XTX Red Devil version also appeared high temperature, the reason is equally ironic.
According to experience, RX 7900 XTX board card average core temperature, hot spot temperature difference is generally 18-19℃, sapphire Nitro+ about 22℃.
But, The average temperature of the red devil is 80℃, the hot spot temperature can reach 110℃, the difference between the two reaches 30℃, obviously abnormal.
Infrared thermometry display,The highest temperature of the GPU area on the back of the graphics card can also reach 77.25℃, and the corresponding position of the power supply circuit and video memory is about 80℃.
When you break it down,There is no silicone grease on the GPU chip at all. Whether it is a central GCD or the six peripheral MCDS, there are many places without silicone grease.
The solution is simple: reapply silicone grease evenly.
Let's test it again,The core temperature drops to 75℃, the hot spot temperature drops to 95℃, the difference between the two cooling 20℃.
The temperature of the GPU on the back reaches 71.881 ° C, and the position corresponding to the power supply circuit and video memory reaches about 77 ° C.
The voice quickly answered,Confirm a few RX 7900 XTX Red Devil version does have improper installation of heat dissipation problems, promised to carefully install the radiator, silicone grease, and stressed that the affected is only a few batches of times, but the specific number of unknown.
At least according to Igor's Lab, they're not alone.
