For our temperature testing, we measure the peak GPU core temperature under load. A reading under load comes from running Metro Exodus Enhanced Edition for 30 minutes.
As for thermal performance, the Gaming OC delivers solid results, with the OC BIOS recording a peak GPU temperature of 65.6C, while the Silent BIOS runs about 3C warmer. The hot spot results are slightly higher than what we'd expect, with about a 12-13C delta between the hot spot and the GPU reading, and though the results are still absolutely fine, the likes of the Inno3D X3 OC and Palit GameRock OC do better here.
