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.

Fan was loud under load in Balanced mode
Team Pandory found the fan loud during gaming in Balanced mode on his 32GB/512GB K16, with more noise in Performance mode. This is an attributed observation, not a standardized noise measurement.

Fan was barely noticeable during Dota 2
Mash IT said he hardly noticed the fan while playing Dota 2 in Performance mode on his 32GB/1TB K16. His result differs from Team Pandory's load test; firmware and room conditions were not established as equivalent.

Booted from a USB-C power-delivery dock
Mash IT unplugged the barrel power supply and powered the K16 from a 100W USB-C dock. This verifies that connection in his setup; it does not establish compatibility with every dock or sustained performance at every power limit.

Ubuntu detected the main devices
Lon.TV reported working display, audio, Wi-Fi, Ethernet and Bluetooth after installing Ubuntu on his 16GB/512GB G3 Plus. The Ubuntu version was not specified, so this is limited to his tested setup.

A newer Linux kernel enabled graphics benchmarks
Jeff Geerling could not run some GPU benchmarks with his initial Ubuntu setup. Updating to Linux 6.12 enabled GLMark2 and GravityMark. His published system record identifies Ubuntu 24.04 with kernel 6.12.3 and a replacement SSD.
