Buzzing Rotating sound from TB MBP

Lately, when I wake my computer from a prolonged sleep. I hear a buzzing or rotating sound from the top right-center part of the computer. It goes away after a minute or so. Any know about this?

Could well be the fan they spin up on waking from deep sleep and then settle down to 0 rpm if your workload doesn't need the cooling. Try and put the system under pressure and get them spinning to see if the noise comes back if so then you may well have a fan bearing issue, that’s the only mechanical thing in the whole computer so it’s probably that.
