Fritzchens Fitz, known in the PC enthusiast community for his high-detail silicon die photography, attempted thermal imaging on an AMD "Renoir" mobile processor with great success. He discovered that the processor can survive without any cooling (not even passive cooling, but the bare processor exposed to the air). A 4-core Ryzen 3 4300U "Renoir" was used in the experiment. The thermal camera picked up that only one of the two CCXs was active during the tests. Not only was the processor found to start, but was also found to be bench-stable with Cinebench R15 and "Crysis" benchmark, during the experiment's 10-minute runtime. Cinebench R15 and 3DMark TimeSpy scores were also obtained. Find the video in the source link below.
