Just received my base Mac Studio (M2 Max), and during initial setup and playing around with some basic stuff it’s been VERY silent! No whine at all! Only when I put my ear within 5-10 cm distance to the backside of the machine can I start hearing a subtle fan sound (again: not whine noise!). As soon as I move my head further away, the fan sound completely disappears. And I do have a pretty sensitive hearing, so this is extremely promising! And, just to mention the real reason I bought this machine: the performance appears to be an enormous step up from my old M1 Mac Mini. Wow! In Logic Pro it seems to use less than half the CPU ressouces. This will probably last me at least 3-4 years. I will report back if anything changes on the whine front.
I’ve got an M1 Max exactly like that ☺️
