Very High Pitched and Super Quiet beep/sound from DV6

They seem to make a new DV6 every year but This one is mine.

I've had this notebook since September and its awesome. But there is a very annoying issue I have always had with it. When I'm using it in a very quiet environment I can hear it emit a high pitched beep type sound every second. Its extremely quiet but its one of those sounds your brain suddenly notices and you can't stop hearing it - like when some old CRT monitors and tube TV's are left on. I usually only hear it when the PC is idle or doing very basic tasks like I'm doing now typing this. I thought for sure it was something else in my home for the first month until I was using the notebook someplace else and heard the same annoying sound. When I put my ear up to the notebook I can hear it better and that its somehow tied with the fan. I can hear the fan barely slow down by probably 5%, then that beep and the fan speeds up again. This happens continuously until I'm not idle. Anyone else notice this? My motherboard was replaced a month ago (It randomly died) but nothing changed.

Might this be "CPU whine"?
