Some Mac Studio owners have noticed that their machines are making a high-pitched whine that appears to come from the fan. There are pages of complaints on the MacRumors forums about the issue, and it seems to be affecting a number of users.

Most of the complaints are coming from people who chose the M1 Max over the Ultra version, which is not a surprise.

Users who are experiencing issues have described the noise as a high-frequency sound that is difficult to ignore, and it is in addition to the standard fan noise. The reader is from MacRumors.

Hi, I've been following this thread and wanted to share my experience with the Mac Studio. I ordered the M1 Max version with 32 Core GPU and 64 GB Ram. After a week or two I started noticing a high pitched whining sound. The ordinary fan noise was audible but not disturbingly so. The high pitched sound was sth I couldn't ignore. I have a relatively quite working space and the sound kept being distractive. I decided to take my studio to the apple store after contacting apple support and trying a bunch of software fixes like reinstalling the os. After a day of inspection the tech guy at the apple store claimed it was just normal fan noise within the expected range of noises and said they couldn't do anything about it. Disappointed I called apple support again and they agreed to send me a replacement, which I am currently waiting for.

All of the complaints seem to describe the same noise. The reader is from MacRumors.

Just unboxed my Mac Studio with M1max (64GB RAM, 32 Cores GPU, 1TB SSD). There is definitely an annoying noise at exactly 2120hz (I compared it using a sinus wave generator). I am pretty sure this comes from the fan and is not a coil whine, since the frequency changes when the fan speed changes. Definitely not acceptable for a product with this price tag...

One machine is experiencing issues while the other is not, because the M1 Max and M1 Ultra have different heatsinks. The M1 Ultra is equipped with a larger copper heatsink, which may prevent the fan from kicking on as often.

Some people have said that they do not hear an unusual sound, but not all models seem to be experiencing this problem. Many people who are unhappy with their machines seem to beExperiencing the high-pitched sound rather than the typical fan noise, but there are some complaints just about the level of the fan noise alone without the whine.

If you are within the two week return period, you can get a replacement from Apple. It is not clear if this is something that can be addressed in a software update or if it is a hardware issue that Apple is dealing with.
