Benchmarking tests rule out overheating problems on the console.
Microsoft designed an effective cooling system for the Xbox Series X, which promises to keep it cold and remains quiet. The parallel cooling architecture will be functional for several reasons, such as the split console motherboard and the use of a steam chamber.
However, the console wasn't spared from controversy, as false reports indicated the Series X was getting excessively hot while playing. Microsoft denied these reports and claimed that the console would emit as much heat as the Xbox One X.
Further testing was done on the Xbox Series X in a controlled environment.
VentureBeat's Jeff Grub tested Xbox Series X to measure its average temperature. He used heating sensors to detect the console's temperature and compare it with the PS4 Pro and Xbox One X.
It's essential to mention that he placed the sensors inside the consoles, but not directly in their internal components, as Grubb didn't open them. On the other hand, the tests were done with a 10-minute gameplay test of Hitman 2.
The average temperature of Xbox Series X during the process was 47.7°C, with a maximum 50.4°C peak. Meaning that it's below the PS4 Pro levels, whose average and maximum temperatures were 62.5°C and 65°C, respectively.
Xbox Series X improved the Xbox One X temperatures, which averaged 52.1°C and 54.5°C. Grubb also tested an RTX 3080 and Ryzen 9 3900XT PC, which had a maximum of 44.1°C and an average of 35.5°C.
Another interesting detail is that the Series X had a minimum temperature of 38.9°C during the process, which is low compared to the 60.1°C of the PS4 Pro.
Grubb later added that Seagate expansion cards reach a temperature of 50°C when in use. Despite this, he clarifies that heat doesn't cause injuries, but it can surprise users.
He ended by stating that his test isn't perfect but that it certainly works to rule out overheating problems.
