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.
Thermally, the 3070 Founders Edition cooler is a definite success. Across our stress test, we saw a peak temperature of 72C, with a steady state result of 71C. This means the GPU is cooler than the 3080 Founders Edition, despite its smaller heatsink and adjusted fan configuration. It will be fascinating to see how solutions from Nvidia’s partners, like MSI, Gigabyte and ASUS, can improve on these results.
