Who wins on what

Ranked by what users actually praise

Overall Impression

Quiet, cool operation makes it excellent for non-gaming daily use. Multiple users report the K9 stays silent and cool to the touch during regular use, with no mouse lag, contrasting favorably against hotter, noisier alternatives like an i9-equipped Geekom mini PC. One owner specifically recommends it for buyers who don't plan to game, citing the low heat output as the standout difference versus competing mini PCs they also own.

Gaming performance is inconsistent, plagued by stuttering and driver quirks. Commenters describe stuttering in Cyberpunk 2077 and Fortnite, often attributed to Intel Arc's driver immaturity, DX11 emulation weaknesses, or thermal throttling despite moderate 70C temperatures. Suggested workarounds include switching to DX12 or reinstalling Arc drivers, though issues reportedly return. Some note even higher-end systems saw similar stutters after a Windows update, muddying the cause.

The small cooling fan is a recurring complaint for noise and design. Several commenters cite around 45dB fan noise and criticize the tiny fan/poor ventilation used to cool RAM and SSD, calling on manufacturers to stop this practice. Multiple users ask whether the fan can be swapped for a quieter 40mm Noctua unit, and one suggests GMKtec could address it via a BIOS update or larger chassis with a bigger fan.
