Memory-heavy stress exposed a cooling limit
Jeff Geerling reported overheating and inconsistent results in a 7-Zip benchmark on his review unit. Repasting did not fully resolve his concern; removing the cover and adding airflow let him complete consistent comparisons. His later benchmark results use that modified cooling setup.

A newer Linux kernel enabled graphics benchmarks
