I believe we are seeing similar behaviours with the drivers. As a temporary workaround, we have asked the manufacturers to supply us with a BIOS that disabled THRM-Throttling. So far, things are looking good, but we are still doing more testing.

In our case, we are running the unit in mobile environment, with not much ventilation. In our test environment, the unit runs fine at temperatures of 80-90 degrees. In the real environment, we only expect temperatures of 50-70 degrees.
