I do not see the noise on LGs site or spec list, noise is vary important when you have that 'movie moment' you don't want to hear *WERRR* of a fan. Did LG tell you the Audible Noise (example: 23 dB) for this model. It is kinda expensive to buy not knowing this.Just like anything with a fan in it, they should publish there audible noise, I suspect that it it was too bad Linus may have tried a Noctua-refit.
I did tweet @LGUS the question, hope to get an answer.
