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.
Moving onto thermal performance, we can see that the iChill X3 does sit at the top of the chart, coming in fractionally hotter than Nvidia’s Founders Edition and the Gigabyte Gaming OC when using the Silent BIOS. That said, a peak GPU temperature that’s below 64C is hardly worth complaining about, while the hot spot is under 75C as well.
