Palit RTX 4090 GameRock OC Review – Midnight Kaleidoscope

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 out of the box thermal performance, here we tested both the Silent and the Performance BIOS. There’s not a lot of difference between the two modes however, with the Performance BIOS hitting 65.3C on the GPU, compared to 66.7C for the Silent BIOS, while we can see just a 1C difference between the Hot Spot temperatures as well.
