Owner-tested local AI 26B and 27B models demonstrated
Takashi Yoshinaga says he purchased the A9 Mega for local-AI work and found Gemma 4 26B A4B text generation fast, simple multimodal image recognition practical, and Qwen 3.6 27B usable in the short demonstration. The video does not report a repeatable tokens-per-second measurement.

Pre-production gaming demonstration Hands-on prototype; no FPS retained

4Is it loud or hot?
GEEKOM A9 Mega
-
Cooling hardware Dual fan plus vapor chamber
GEEKOM's IceBlast 5.0 system uses two fans and a full-coverage vapor chamber. The public product page claims this supports 120 W sustained operation, but the retained exact-model YouTube sources do not provide controlled temperature or sound-level measurements.

GEEKOM -
Independent acoustics status No controlled dB result
The retained owner video focuses on local AI, while the IFA hands-on used a show-floor prototype. Neither establishes retail-unit idle or load acoustics, so no decibel value is published here.
