So, we set out looking for clues. In order to exclude our systems as the source of error, we tested them extensively.

We started with a new, clean Windows image with old and new drivers. We switched between three motherboards from different manufacturers (Asus, Gigabyte, and ASRock) using the latest BIOS. Still nothing to report.

But after we flashed back from BIOS 0503 to the old 0304 (used for our launch review) on Asus' X399 ROG Zenith motherboard, we saw the old temperature values once again, in addition to the already-documented stability problems. We therefore hypothesize that the cause of the error is the AGESA code 1003 Patch 4, and that it is displaying the calculated temperatures incorrectly during overclocking, with the potential for reduced fan curves during increased power consumption.

We tested further with a much weaker AIO cooler, and our overclocking led to significantly lower fan speeds when using the motherboard's PWM-controlled fans. The result is a thermal accident waiting to happen. An air cooler is therefore out of the question for now.

We have already informed AMD about these measurements, and we are awaiting a statement or a new BIOS, which we will re-test for an update. For now, we recommend manually controlling the fans when using the current BIOS versions.
