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.
In terms of temperatures, the XLR8 is a decent cooler. It kept the GPU temperature to just 68C, while the hot spot peaked at just 80C. It's not much better than the Palit StormX OC, but it's certainly good enough to not be a problem for the card.
