I have the same problem with this noise. I thought also that it is not driver problem and the reason is electronic interference on the motherboard. But I noticed, that iif CPUs work at 100%, there are no noises!!! Can somebody explain me this wonder?

I tested this with simple program: "int main(void){ for(;;); return 0;}"
If each core execute a program, there are no noises!
