For our temperature testing, we measure steady-state GPU temperatures under load. A reading under load comes from running A Plague Tale: Requiem for 30 minutes.
As for out of the box thermal performance, the GamingPro OC sits in the middle of the chart. It is a clear improvement over the MSI Ventus 3X, regardless of which BIOS mode is used, though the Vanguard SOC offers even lower temperatures. Still, on an objective level, GPU temperatures below 65C and memory at or below 70C is great to see.
