Coil whine

[antanas]

Hi, my new DEC750 is producing an audible coil whine. Is it a normal behavior with these devices?

I don't have this device but as far as I can see it has SSD inside and those are known to produce sounds comparable to coil whine during normal operation. Is your environment very silent (eg. enough to hear those faint SSD noises)?
