FWIW Coil Whine affects some machines much more than others.

The sad part is, coil whine is unpredictable, two machines with the same make/models can behave differently.

Coil whine is usually much more noticeable when you fully load a system too.

What I would do is buy components and then fully load them as much as I could, and RMA anything with noticeable whine.

It's not "normal", Dell XPSs for example were notorious for bad coil whine where as my macbook air doesn't have any at all.
