Hei, Stupid question, i know, but has any of you ever put your ear on the Surface Pro 3 in near absolute silence? Okay... absolut silence doesn't exit! But take a realy realy realy silent room! Don't heat the Tab so the fan doesn't run. Your Surface Pro 3 is absolutly silent? Right? That's what i tought too! But then i watched a video, muted the sound, and tought i could still hear the video! So, as foolish as i might look, i put my ear on the front display where the CPU is situated! And i heard a noise.... somewhat hard to describe... maybe like a realy silent running HDD.... maybe a high (though not too high) pitched beeeeeeep So just to be sure i restartet my device, tried again and it sounded more like the heads of a HDD working. Then i tried on the Backside, where the CPU is situated, and hear a synchronous scratching, maybe like the fan that was running/stopping/running/stopping at a realy low RPM. And right now i hear a ticking like tick/tick/tick/tick that goes kinda fast paced. Sure i agree that this is absolutly irrelevant as you can't hear anything as soon as there is a little noise like breathing or you're further than 10cm away from the tab. But still there is my curiositiy (lucky i'm not a cat!) and i'd really know what is making this noise! Logically thinking it's either the fan (the only rotating device in this Tablet) or the transistors working (remeber that case with the AMD GPU's ?) So, what do you guys think?
