Hi Dark Mantis, the noise I get is a mixture of high and mid pitched noises. The noise it makes, depends on what I am doing on the computer. For example, when loading Windows or shutting it down, I get a complex beeping and buzzing and blipping, intermittently on and off. When I am running HD Tune benchmark, I get a constant tone beeping. When I am browsing in and out of folders in windows explorer, I get a blip noise as I change folder. And when I am running DPC latency checker, there is a blip blip blip noise. So it varies.
My noise does not induce any vibration though.
Also, when I turn off C1E, the noise is gone.
So it appears we have differently behaving UD7s.
