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.
Out of the box thermal performance is a fascinating area to look at. These figures are recorded using the cards' default fan curves, so they don't account for differences in fan speeds and therefore noise, but they are representative of the out of the box thermal performance you can expect.
What we can see though is pretty much the same sort of temperatures across all four cards. There's only small differences in the GPU and hot-spot temperatures, with no more than a 4C margin at most, so let's take a look at the acoustic performance and see if that explains things…
