In Windows Defender, the application is on the exception list. I'm not sure how to set folders as exceptions.
I downloaded HWINFO64 and the NVMe Drive SMART check is all OK, and the drive temp is 61c. The warning temp is set to 80c and the critical temp is set to 82c.
Also noted that the fan is running steadily (CPU & GPU) at 3800-3900RPM.
