What to Look For
Key factors to consider before buying on AliExpress
Fanless PCs use the metal case as a heatsink. N100/N150 are fine for 24/7 low-load use. Sustained 100% CPU load causes thermal throttling. Avoid fanless for heavy workloads.
True zero noise — no fan whine, no moving parts. Compare to active-cooled mini PCs at 15-25dB idle. Perfect for bedrooms and recording studios.
Ideal for: Home Assistant, Pi-hole, firewall, light NAS, digital signage. Not ideal for: Media transcoding, gaming, heavy Docker loads.

Sustained 100% CPU load causes thermal throttling. N100/N150 handle casual workloads indefinitely.
For direct play, yes. For transcoding, a fanless N100 may throttle. Use a larger chassis with better thermal mass.
