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.
The difference between the two BIOS modes becomes clear when looking at thermals. As a result of its more relaxed fan curve, the Silent BIOS runs hotter, hitting a peak of 76C. The OC BIOS, with its more aggressive fan curve, runs a few degrees cooler, peaking at 72C. Both are improvements over the reference card, but noise levels also play a part in this, as we will see on the next page.
