Whine noise from computer

[TetchyIRL]

EDIT SOLUTION: I left the motherboard speaker hooked in and for some reason it was going nuts and making that sound.  Sigh lol

 

Just finished a fresh build for the wife. A 'whine' noise is coming from the computer and the wife thinks it's bad. I hear it but, it doesn't concern me. Either way, I'd just like to check with you aces to see if this noise should be cause for concern?

Only way to find where noise is coming from is to unplug 1 device at a time until it disappears. Could be from the power supply, front audio jacks, or RGB light strip but, I've never heard that specific type of whine before.
