This black box is making noise--what is it? (pictures)

Question

I know there have been several threads regarding the white noise given off by Motherboards under heavy load.  I also have a K7N2G-ILSR and it has made the noise since day one.  Like others, I have tracked the noise to the little black box just above the mosfets near the CPU.
When I press on it, the pitch of the noise varies.  Ideally, I would like to strip the tape from around the box and hot-glue the entire thing, but I want to make sure it won't hose everything. I don't care about the warranty, but if I can't make the sound stop, I'm liable to kill someone.
I would like to know what the black box does and if anyone has any luck silencing the sound!
Thanks!

Answer 1

In this case it stores energy and timely releases it, In MSI's words, this is normal, as the environment is high frequency.
To elaborate further on what I said before, what's likely happening is some of the components or that choke may be at the bottom or top of the allowable tolerance for manufacture. All electronics are not EXACTLY the same as far as components go. This is what's referred to as "parametric differences." You have the PCB, (printed circuitboard) CPU, RAM, peripherals, power supply, and, add to that, all the components that populate a PCB. A PCB is used on your VGA card, RAM, power supply, and ALL of your peripherals. All of these parts are manufactured with allowable tolerances, same goes for the PCB. Get the idea? See how this becomes an environment where things can easily get out of hand? Couple that with the fact of how many possible configurations can take place, and also that many of the componets and parts are manufactured by many different vendors.
Take a circuit board for example, you have multiple layers, dielectric in between those layers, the foil or copper layers in the internals are a set weight or thickness but the outer layers are usually plated up and/or etched down (this can include the internals). The etch process is done with acid, and you get a minute bit of what's called "etch down" where if you were to look at a cross section of a routed trace, you would notice that there is a slight "V" shape since the acid will etch around the sides. The board vendor must compensate for the etch down by enlarging the original artwork. However, it will NEVER be exact every time. The general specs for most of the boards we produce are +/- 20% of the original artwork supplied in the design data. That is, if you have an .008 thousandths trace, we can be within .0016 of the original.
Granted some tolerances are tighter when manufacturing high speed and impedance controlled designs, but you get the idea.
Now, you have basically the same scenario when it comes to components as mentioned previously. That is why you see users reporting strange behavior, mind you, it's a small percentage, but it is generally exacerbated when multiple parts, components, and peripherals operate in a high speed, high frequency environment like today's performance PC's. It only takes a few things to be at the top or the bottom of a tolerance to create this anomaly, or another issue altogether.
This is what I know personally through my experience as a PCB designer and manufacturer, and then being in the electronics and IT industry, and of course, an enthusiast
