Recently, NVIDIA was involved in the melting 16-pin connection scandal, but now AMD is experiencing heating issues. According to reports and user comments, the Radeon RX 7900 XTX can reach temperatures of 110 degrees Celsius. Therefore, PowerColor, one of AMD’s most prominent partners, has requested user reports on Reddit so that it can forward the information to AMD for further investigation.
The 110C hotspot issue appears to only affect MBA (Made By AMD) or Radeon RX 7900 series graphics cards, regardless of whether you obtained them directly from AMD or one of its partners. Since there are no reports of affected custom designs, the reference cooler may have a design issue. Let’s hold off on making assumptions though, but whether a junction temperature of 110 degrees Celsius is acceptable for Radeon RX 7900 series graphics cards is a million dollar question.
Radeon graphics cards are prioritized to exceed 110 degrees Celsius, which is consistent with AMD’s requirements. If you recall, the usual junction temperature for Radeon RX 5700 series graphics cards, such as the Radeon RX 5700 XT, was 110 degrees Celsius. Rather than setting a cautious, “worst case” throttling temperature for the entire chip, the Radeon RX 5700 Series GPUs will opportunistically and aggressively continue to increase speeds until one of the many available sensors hits the “hotspot” or ” Junction’ temperature reached 110 degrees. Celsius. In a blog post from three years ago, AMD stated “operating at junction temperatures of up to 110C during normal gaming use is expected and within spec.”
In addition to junction temperature, it is crucial to examine the edge temperature to determine if there is an underlying problem. Edge temperature refers to the temperature recorded at the edge of the silicon. Therefore, it is a good indicator of the rising pressure situation. A low number indicates favorable mounting pressure. “110 hotspot is within spec if your card’s GPU edge temperature is 90° or higher… If 110 is reached at 70 edges, it’s not ideal,” an AMD spokesperson wrote on Reddit.
AMD has said their GPU team is currently investigating the issue. It is vital to determine if the high temperatures are responsible for the thermal throttling causing the graphics card clock speed to drop below its rated speed. Otherwise, this is default behavior. Remember that AMD only guarantees the base clock speeds of its graphics cards. Radeon RX 7900 XTX graphics card users are apparently RMAing or returning their products. Nevertheless, the reactions are mixed. Some users on Reddit said AMD accepted their RMA, while others claimed the chipmaker denied their RMA and refunds.
Some user reports indicate that re-pasting the Radeon RX 7900 XTX fixes the problem, although this is not always the case. There is a suggestion that the cold plate of the cooler is uneven. That explains why the thermal interface material (TIM) is thicker in the center of the mold than at the edge. A Reddit user recommended a graphite heat pad as a possible solution. In previous generations of Radeon graphics cards, AMD opted for thermal pads; so it’s unclear why the chipmaker decided to use TIM on RDNA 3. In any case, we do not recommend removing your cooler as this will certainly void your warranty. Currently the only options are waiting for AMD’s instructions or trying to RMA the graphics card, although the latter would only be effective if the hardware performs as intended.
