Frogfoot Dual ONT Box

[chrisbaker1981]

HI, anyone familiar with the newer Dual ONT boxes Frogfoot are installing these days?
Attached photo.

It makes a really annoying high pitched ringing sound the whole time, similar to old fashioned TVs.
I assume its just some internal electronics vibrating as current passes over, but its super annoying and wondering if its possible to stop it?
Im powering it with a 12v 24w power adaptor.

You are describing coil whine.

Had the same noise on my GTX 460 when a games intro played at 1200 FPS, you will have to ask for a replacement.

Have you tried another same spec PSU?

Yip, they will remove/replace that sh|t if it was mine.

That piece of Chinesium has cheap inductors in it's regulator section, that's what you're hearing. Coil whine is the colloquial term for a broader type of design flaw.
