I bought this as a TV streaming unit, returned as soon as I heard the fan running at moderately high speeds. It literally sounds like a jet engine, or as someone else described here, hotel house keeping running vacuum cleaner in the room next door. Asus claims this to be a low noise PC and maybe their decibel values are accurate, but the high pitch noise is horrendous. I wish I could keep the unit because other than the noise, it is great in a lot of ways. I went with the Cubi 3 Silent instead. If you don't mind tinkering a bit, NUC8 with Akasa Turing fanless case is even better.
