annoying high pitch tone on expensive MacStudio ULTRA

[jelko]

as mentioned in the title, my ULTRA-Expensive MacStudio Ultra makes an annoying high pitch tone! i tought maybe this comes from the fans. i tested the app "FanControl" in order to lower the fan speed. the high pitch tone is still hearable.

this should NOT happen with such a expensive machine!

it apears im not the only one "suffering" from this issue.

anyone else?

It probably is coil whine and has been reported by many MacStudio owners. Perhaps talk to Apple to see if they can help you with it as it will not go away.

Keep exchanging it until you get one that doesn't have the problem. Sucks, but it's the only solution.

make sure that the ultra isn't on the same circuit as some of the older dimmer switches
if not, exchange it
