They can fix it easily by releasing OS update that tweaks the fan curve, maybe lower the idle fan speed or stop it completely while not under load like the MacBook.

Mac Studio Owners Complain of Irritating High-Pitched Noise

If you use Mac Fan Control to slow down the fans and wind up damaging your Mac Studio because of overheating I’m pretty sure you will have voided your warranty.
M1 max and it's silent at my user position. The MS is under my ASD about 20" from me.
This might help: go to a bunch of punk shows like I did in my 20s. Don't wear earplugs. Listen to headphones too loud a lot, just for good measure. Guaranteed a little high-pitched noise will be out of range :/
I’m sure most people like me set their fans to a faster speeds not a slower speeds because heat is the enemy.
I just want to know where I get a sinus wave generator... 🤔🤔🤔
im right on the edge, well over 200 shows under belt and I can only hear it if I turn my head a certain way. Kinda funny, kinda sad.
I heard a rumor once that Mac's are often used in settings like recording and movie studios. This would imply that the people using them are often people who have quite well trained ears and a critical need for their hardware to not produce background noise.
While don't doubt that you can't hear it, it doesn't mean that it isn't there.
I hear a high-pitched whining sound whenever I open the Twitter app. Started pretty recently. Not sure if that is related.
No they can't, Coil whine is not going to be RPM dependent. That's why this issue is important to bring to light (thanks Juli!) Apple needs to know if this is widespread and get pressure publicly to go sort out whatever component is causing it. So we don't have another MBP 16" situation where the solution to the graphics card drawing too much power was to buy a brand new laptop because they never acknowledged / fixed the issue.
There are 2 versions of the PSU boards and that may be a contributing factor, but tearing everything down to the PSU is a huge pain and I doubt we'll get enough people doing that to know one way or the other.
If an RPM change is modifying this behavior it could possibly be some issue with the fan bearing but I would bet more that it's changing the power draw just enough on whatever circuitry is impacted that it causes or stops it / masks it with higher airflow.
My order came up early for a maxed-out Studio and I'm holding off due to this... there are too many reports for it to be a fluke. I can handle a little fan noise but coil whine is not acceptable especially in a product this expensive.
Alternate caption: "Purchasers of Apple's third-generation Power Macintosh Cube are complaining of issues that plagued both the first and second generations of that product line."
It shouldn't be possible. Note that Apple sells M1-series computers without any fans (e.g. the Air).
If the fan is too slow to control the heat, you'll experience reduced performance due to thermal throttling, but nothing should be damaged.
Same here, I have the 32GB model as well. Silent. In fact the exhaust air from the back is cooler than the air in front. It's like a fridge. LOL
Oh man, it is there for sure. Already it has been messing with measurements but to deal with it I stuck the computer in a cabinet. I haven’t homed in on the exact frequency range because I’ve been too busy to deal with it until I saw this article and comment thread. Will post my findings later today if people are interested.
Context: I design speakers as a hobby and use my Studio M1 Ultra for running tests and optimizing DSP for systems I’m working on. The previous computer was an M1 Mini. My office is pretty well optimized for sound testing but the Studio threw that for a loop (though outside this sole gripe it has been an outstanding computer)
Guys, no need to panic. It's an undocumented feature known as UMR: Ultrasonic Mosquito Repellent.
I have an M1 Ultra Studio and find the noise really annoying, but I think the problem is that my work computer is a 2021 MacBook Pro whose fans barely spin up from 0 rpm so I've been spoiled with absolute silence.
Fortunately the cooling on the Studio is so good that it seems to work fine in a small cupboard where I can't hear it.

Here in South Florida, we don't have this issue. Our A/C Units do a great job masking any other noises.
That's why the waiting times are so long. Users will age until they get their Studios so that they won't be able to hear those really high frequencies.
