Odd sound ISR 1100

Hey all

I have an ISR-11118P which is the new fanless POE capable ISR router from Cisco for my home office. I have a Meraki AP hanging off it.

The whole setup works well but when I power the router on, even without POE, it emmits a VERY high pitch constant noise.

My Girlfriend can only hear it if I have her listen very closely, but it drives me bonkers. Has anyone seen something like this in networking gear before?

Any suggestions?

This might be the wrong sub but I had no clue where to post this.
