ASUS RTX 4090 TUF Gaming OC Review

For our temperature testing, we measure the peak GPU core temperature under load. A reading under load comes from running Metro Exodus Enhanced Edition for 30 minutes.

Looking now at thermal performance, as expected the Performance BIOS runs the coolest of the two BIOS modes, and it does deliver good results. We see a peak GPU temperature of 65.2C, though the hot spot result is more middling, with a peak of 78.3C. The Quiet BIOS does run a fair bit warmer, warmer than even the Founders Edition, but as we shall see, it is significantly quieter too.
