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.
Cooling performance is mighty impressive for the RTX 3080 TUF Gaming. Using the P BIOS, we saw a peak GPU temperature of just 62C, a reduction of 14C compared to the Founders Edition. Even using the Q BIOS, with its more relaxed fan profile, temperatures did not exceed 69C, so regardless of the BIOS you use thermal performance is excellent across the board.
