Nvidia has talked a lot about evolutionary design solutions for its graphics card cooling systems, which ultimately led to the creation of the reference version GeForce RTX 5090 Founders Edition. However, the company was silent about one change. Reviewers discovered it.

According to Wizzard, a TechPowerUp columnist and creator of the GPU-Z utility, Nvidia has disabled Hot Spot monitoring on GeForce RTX 5090 graphics chips. Other reviewers have also noticed that the data read by the GPU-Z software shows for Hot Spot a constant temperature of 255 degrees Celsius, which, of course, is incorrect information. The reason for this decision on Nvidia’s part remains unknown.
«The Blackwell Nvidia video cards removed Hot Spot monitoring. You can still consider data on the temperature of GPU and memory chips. Although there have always been a lot of disputes around the Hot Spot topic, this function was useful for checking the correctness of the cooler or water block on the video card, ”Wizzard writes in his review of the standard version of the GeForce RTX 5090.
In a conversation with the Videocardz Wizzard portal, I confirmed that Hot Spot monitoring is not available on all GeForce RTX cards of the 50th series, and not just the GeForce RTX 5090. In the future, this indicator will also be removed from the GPU-Z utility.

Observers who want to get the latest version of the GPU-Z program can turn to Wizzard for fresh beta-version of the application in which the GPU Hot Spot monitoring system is already absent. GPU-Z stable version is expected next week, closer to the release of the GEFORCE RTX 5080 video card.
It should be clear that the GPU Hot Spot is not just one temperature sensor. Rather, it is a combined information read by sensors on the graphics chip crystal and showing the temperature of the hottest GPU core. The operation of the function is controlled by the BIOS of the video card. It is possible that the Hot Spot monitoring system will return in the future, but for now Nvidia has blocked access to this data.
