Sinusoidal
Sure, so then write "sinusoidal."
Or "sine." Or "sinusoidal wave."
I have never seen sinusoidal abbreviated to "sinus."
Crazy. I bought the exact same model and specs, took it to the apple store last week and had the same result. Very disappointing. tomorrow is my last day to return it with the 14 day window. For the price this machine should be perfect. I have a friend with a studio and it’s dead silent. Sounds like faulty fans in some models.I bought the Mac Studio M1 Max with baseline CPU/GPU, 32gig ram, 2tb SSD, and had the issue with the whine. It was still present at 1100 RPM of the fan.
I actually brought it to an Apple store, and they told me they could not reproduce the issue and all the hardware was normal and would not do anything about it. I'm guessing the room they tested it in was not as quiet as my home office since it's only audible when there is no other noise.
Debating if I should return it and wait another 6-8 weeks in hopes that another new one won't have the same issue...
Hi Sun Baked, very good thinking, in this case solution is to supply Mac Studio through UPS, I'm testing it now I had a peak when running at 1100 rpm and it's still here using UPS, I can't test anything more since my unit works very well.If you have a friend that has a silent Mac Studio, and have also been unable to reproduce the sound at the Apple Store.
Try one more experiment, take your machine to your friends house, and plug your Mac Studio into his setup.
If it is silent at both the Apple Store and your friend's place, then it might be a power related issue at your place.
UPS normally does not intervene unless there is an over/undervolt condition or a power cut, so you’d be getting straight wall power all other times.Hi Sun Baked, very good thinking, in this case solution is to supply Mac Studio through UPS, I'm testing it now I had a peak when running at 1100 rpm and it's still here using UPS, I can't test anything more since my unit works very well.

He is really annoying to me. It's not his hate of apple, he's just super annoying.Don't post Linus videos around here. MacRumors members hate the guy, for some reason.
The Apple Store is worthless for this issue. They tested the machine on the countertop in the store with all the store background noise. You will never hear the noise that way.If you have a friend that has a silent Mac Studio, and have also been unable to reproduce the sound at the Apple Store.

Not sure how good this test is, but I used Macs Fan Control and set the fans to 1100 and it is much quieter. I then ran the Heaven Benchmark full screen on Studio Display and the highest temp I saw was a GPU cluster at 51C. I then switched the fan to automatic (starts at 1330rpm) and ran Heaven again - there was really no difference in temp on any sensor, and the fan was never increased above ~1330rpm.I’m sure most people like me set their fans to a faster speeds not a slower speeds because heat is the enemy.![]()
Yes you’re right about the use of battery/inverter, but the main is filtered and regulated including surge protection to supply equipment and battery charger that’s better than raw main.UPS normally does not intervene unless there is an over/undervolt condition or a power cut, so you’d be getting straight wall power all other times.
Yeah. I am on my second model. Better then the first one. But still , i can hear the whine. No review mentioned is. Fishy very muchUgh. My M1 Max Studio was just delivered and it has the fan whine. It is not subtle. It sounds like an old spinning hard drive. I'm surprised at how loud the normal fan noise is (about the same as my Dell mini tower) at idle, but the whine on top of that is intolerable. After months of reviews saying how silent it is I am very disappointed, in both Apple and the reviewers.
It looks like a nice machine, but the noise is a deal killer. Back it goes. Sigh.
[update]
After calling for a refund, the person on the other end said they had just processed half a dozen return requests for the fan noise. Apple knows this is a problem. When or how it gets fixed is another matter. I must have watched a dozen youtube reviews and they all gushed about how silent the machine is. ??? Something up there.
I am tinking the same. Its like they new they messeg up with the fans and they just lockef them. I mean, do you any other desktop machine that has fixed fan rpm????Not sure how good this test is, but I used Macs Fan Control and set the fans to 1100 and it is much quieter. I then ran the Heaven Benchmark full screen on Studio Display and the highest temp I saw was a GPU cluster at 51C.

Interestingly as the fan goes from 1100 to 1330 I hear a whine on the way up that then disappears. It makes me wonder if Apple knew there was some sort of "whine noise" issues below 1330 and that is why they default to 1330. On my Studio Max, it appears to be around 1200 where it is more noticeable. For now I'm going to live at 1100 and keep an eye on temperatures when stressing the machine and see how that works out...
Some are still coming in bad, you just have to read all the threads about it, not just this one. The threads in the Studio forum have more information. A recent poll thread added up to 30% bad. I bet it's not that bad but it does mean there is definitely a problem.It went quiet (no pun intented) in this thread. It surprises me a bit. Since more people should have gotten their mac studios and i am sure there are more problems….
Is the whine constantly there or just sometimes? Mine is not all the time there. Only when the fans readjust rpmToday got my CTO Studio with an M1 Ultra. Unfortunately it has the whine, so this is not limited to M1 Max configurations. Tried to change the fan speed using Macs Fan Control but even at 1100 rpm it is still audible, in fact it is even worse. I decided to try to get used to it while it is in the return period. If not, I may return it. It is unfortunate, because it is much faster than the iMac 2015 it is supposed to replace, which also was CTO with the highest CPU configuration. The Studio is 6 times faster for my workflow.
I don't think this is coil whine from the SSD. The dB and the frequency of the whine definitely changes with different fan speeds and it is a continuous whine unlike SSD coil whine. Most probably the fans used in the device are not very good quality and the sound comes from the bearings.
