P4 high pitch buzzing

[LC8Sumi]

Hello fellow reefers & GHL users
My new P4 is making a quiet high-pitch buzzing sound, coming from inside the box. I was wondering if this is normal & others also have it?

Is it the alarm?

No, it’s something with the electronics. Like a condensator or such

Mine has never made noise other than the alarm. It makes a really odd sound imo.

It’s really faint. First I thought it was comming from the power supply as some tend to make noises, but it is coming from the p4 unit itself.

Can you video it and post it?

I’ve tried to, but it’s so faint and so high pitch that the mike on my phone can’t pick it up I can live with the sound as I only hear it when I put my ears very close. If it’s not effecting the operation of the unit, then it’s not a problem
