Nucleus+The network port is constantly creaking, is it a malfunction?Do you need maintenance?

Whilst we await the definition of creaking, it may be coil whine? It may just be more audible from that end of the NUC? See thread below:

Noise from a Nucleus rev B

Hi Guys, I have a Nucleus acting as roon server with only the power cable and the ethernet cable attached to it. Then, i use an Esoteric Streaming dac to play Tidal streaming exclusively. I am finding strange that from my couch i can hear the Nucleus making a noise i usually relate to writing to an old HDD. I even opened the Nucleus to confirm there is no HDD inside…and its not. Is this normal? Where this writing noise comes from? Thanks for your help
