For our temperature testing, we measure the peak GPU core temperature under load. A reading under load comes from running Cyberpunk 2077 for 30 minutes.
As for thermal performance, here the Nitro does very well, with the OC BIOS recording a peak GPU temperature of 62C. There is a slightly larger disparity between the GPU and hot spot temperature however, with the latter hitting 88C, perhaps indicating a slight imperfection with the cooler mount – but also know that AMD's chiplet-based GPUs are not perfectly flat due to the MCD and GCDs being slightly different dimensions. The Silent BIOS runs a touch hotter, but still offers a noticeable improvement over the reference card, hitting 70C and 91C, respectively.
