We use CPUID HWMonitor to measure the maximum CPU and GPU temperature after 30 minutes in Grand Theft Auto V running at 4K. To measure idle system temperatures we leave the system running at the desktop for 30 minutes before taking the reading.
As was the case with acoustics, thermal results are also fairly good. The graphics card in this system uses Nvidia's reference design cooler, so hitting 83 degrees Celsius is fairly typical, the processor on the other hand does not exceed 40 degrees under load, which is excellent.
