For our temperature testing, we measure the peak GPU core temperature under load. A reading under load comes from running the 3DMark Time Spy stress test for 30 minutes.
Thermally, the GamingPro OC does well. We saw a peak temperature of 70C across our thirty minute stress test, putting the GamingPro OC right in the mix with the ASUS TUF Gaming and Gigabyte Eagle OC models. It doesn't run quite as cool as those cards, but it is very close, and either way a peak temperature of 70C is very respectable. That's also 3C cooler than the MSI RTX 3080 Gaming X Trio.
