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.

Included SSD ran hot during sustained stress
Robtech found the included 1TB eKit Store SSD reached thermal-throttling territory when he stressed the CPU and SSD together for an extended period. This concern applies to his drive and test conditions; it is not a normalized temperature result.
