Coil whine when opening applications and playing games.

So I completed my build yesterday and have two issues I'm trying to solve.
Issue 1: The pump for the watercooler makes a slight clicking/buzzing sound.
Issue 2: Whenever a game is running or brief moments of opening different applications, I hear coil whine. It's worse when in games. I've tried a different GPU which didn't have the issue on my old PC and the problem persists... Any Ideas??

It happens, might be caused by the PSU, because the newer ones use a very high frequency switching signal to increase the efficiency.
My network card (not integrated pci-e) used to do it, when I was running speedtest, or pushing through a lot of data over the LAN.

I'd say it's normal (unfortunately) and doesn't mean that your hardware is dying or anything like that. I know it's annoying, and you can try to find out what causes it, but it might be difficult.
