Curious question about how much cpu does your mouse use.

Here lately (no idea why or whats doing it) every time I move my mouse I get a electronic hum from inside my case. It honestly sounds like it's coming from the cpu or one of the capacitor's near it but can't pin point it at all.

Anyway, I was checking coretemp and watching my temp and I noticed something strange. At least I think it is. When wiggling the mouse back and forth I noticed it uses anywhere from 50-70% of one of the cores. Either single or added together. So was wondering how much does your's use and if maybe thats my hum issue. The hum is really loud I can hear it over game sound sometimes unless I have it blaring. My box is far from quiet to. Lot's of fans in it.

Edit: I had pretty much came to the conclusion that I had a capacitor going out. If it's my mouse though...thats good news. Already tried disconnecting all my usb items and that didn't help. Also went in and started under volting everything until it was stable to see if it that was the issue.
