AMD’s Radeon RX 7900 XTX graphics cards are known to run hot, with temperatures of over 100C quite common under 4K gaming workloads. Data gathered by HardwareLuxx shows that most models will approach the 90C mark while some even post figures as high as 110C. These temps are far from normal and can lead to clock throttling and a substantial performance deficit.
A Reddit user observed this behavior on his Radeon RX 7900 XTX and asked AMD for a refund. Unfortunately, Team Red shot down his request, stating that the 100C+ temps are quite normal for the RDNA 3 flagship.
As we know so far, Quite many people have problems with the refererence 7900xtx cards, reaching 110 Junction Temps, 100% fan Speed and still loosing performance due downclocking .
I just got the reply of my RMA request:
Thank you for your email.
The temperatures are normal if you there is any issue please, contact us back.
Thanks for contacting AMD.via r/AMD Subreddit
An investigation by Der8auer revealed that these thermal issues result from sheer manufacturing negligence. AMD has been using low-quality thermal paste and pads with inappropriate mounting pressure to cool the Radeon RX 7900 XTX. Replacing the same with aftermarket components fixes the problem. Subsequently manufactured RDNA 3 parts should rectify the problem.
