For our temperature testing, we measure the peak GPU core temperature under load, as well as the GPU temperature with the card idling on the desktop. A reading under load comes from running the 3DMark Fire Strike Ultra stress test 20 times. An idle reading comes after leaving the system on the Windows desktop for 30 minutes.
If you thought the thermal performance of the Strix 2080 was good, the Strix 2080 Ti is even better. Using the performance BIOS, it peaked at just 59C on the GPU core, which is simply fantastic. It did run little louder in this mode, but more on that on the next page.
What really impresses me is how cool the quiet BIOS stays. That peaked at just 72C which is still cooler than Nvidia's Founders Edition, despite being faster – and significantly quieter, as we will again see on the next page.
In terms of our thermal imaging, results are again excellent. We saw a peak of 69.5C on the side of the card, and the peak of 65.6C on the back was from an area of exposed componentry that was not covered by the backplate.
