A (very) hot potato Are AMD’s Radeon RX 7900 XTX reference graphics cards heading for a recall? That’s the nightmare scenario team red could be facing after legendary overclocker Roman ‘der8auer’ Hartung discovered a potential reason for the cards’ overheating issues: a faulty chamber that is vapor.
As a recap, we heard a month or more ago that some AMD Radeon RX 7900 XTX MBA (Made By AMD) guide designs tend to be experiencing thermal dilemmas GPU that is involving hotspot, or the maximum temperature read by the sensor, reaching as high as 110C.
der8auer hoped to uncover the cause of the temps that are high therefore he purchased four Radeon RX 7900 XTX cards to execute some recent tests. It ended up being found that the installation positioning produced huge difference, with horizontal setups increasing temps by 20 levels, nevertheless the issue that is overhearing reared its head after just one minute once the burn-in test started.
The overclocker also investigated factors such as cooler weight and gravity to see if they were influencing the temps that are high. He made use of a specifically created stand to verify they were maybe not area of the issue. Mounting force has also been eliminated as being a cause by dismantling the cooler, eliminating the help bracket, and reducing the standoffs by 1.5mm.
That remaining one concept staying: a challenge utilizing the chamber that is vapor which could be related to the choice of material or a design flaw, possibly preventing the water from traveling back after condensing. Der8auer said he is certain this is where the presssing concern lies. He did not have enough time to use the chamber apart for more investigation but can do therefore inside a video that is future

The overheating is not impacting every Radeon RX 7900 XTX research card: the only we found in our analysis did not show any abnormally large temps. However, a problem in the chamber that is vapor means the problem is more widespread than first realized and likely impacts a higher number of users than Nvidia’s melting 16-pin 12VHPWR adapter issue, which AMD gleefully mocked in a tweet.
AMD last said that it was aware of the problem with its RX 7900 XTX reference cards week. It encouraged users experiencing unanticipated throttling that is thermal contact AMD support.
