I'm also not talking about the fans revving up when not gaming. I get plugging your device in offers turbo boost thus your fans are bound to come in and out even while reading nothing but a word document.
what I'm curious about is the high frequency sound that accompanies it. the fan itself is low(low rpm) naturally because I'm not doing anything, and it comes and goes as I browse(once again, no problem unless this isn't normal too =0).
listen for the high pitched siren.
just so you don't confuse static noise for fans, here is a video of my laptop when the fans are not spinning(plugged in)
either way Im planning on stopping by the MS store but wanted to know your input
