It sounds like item #2 "Vcore malfunction". There are 4
large capacitors and 6 smaller capacitors next to the CPU bracket.
Are the tops of the capacitors perfectly flat, or are they
bulging or domed ? If the capacitors are domed, they are losing
their electrolyte, and the Vcore will fail after a while.
Capacitors can make sound, if the charging and discharging
of the dielectric causes the plates of the capacitor to move.
Look around the base of each capacitor, to see if there is a
brown stain from what looks like fluid leakage.

Is the computer stable, or does it crash a lot ? If it crashes
a lot, you may need to return the board under warranty.
