MacRumors reported that as Apple Mac Studio was released one after another, the first users to experience the device said they were troubled by incomprehensible problems during use-some users said that Mac Studio would always emit an annoying high noise during the operation of the device. frequency fan noise. From what I found out, the problem seems to be focused on the M1 Max version, not the M1 Ultra flagship (the two have different cooling configurations).The unlucky user who was recruited said that this high-frequency noise is difficult to ignore, and the noise emitted when it rotates is far greater than the noise of a normal fan. We saw a MacRumors netizen sunsetblvd wrote: hi, I have been watching this thread, and also want to share my experience using Mac Studio, first I ordered the M1 Max model with 32-core GPU + 64GB RAM. However, to my surprise, after a week or two of use, I suddenly started noticing a high-pitched whine. Because ordinary fan noise isn’t that disturbing, but this high-frequency noise is hard to ignore. And, for me, what I need more is a relatively quiet work environment, but the appearance of this noise makes me always distracted when I work. After first contacting Apple Support and trying a bunch of software fixes (like reinstalling the OS), I had no choice but to send the device to the Apple Store. After a day of checking and waiting, Apple technicians insisted that it was just normal fan noise and expected to be acceptable, so there was nothing they could do about it. Disappointed I called Apple Support again and this time they finally agreed to send me a replacement and are currently waiting for it to arrive.
And another MacRumors netizen named h43m also mentioned: just out of the box a M1 Max version of Mac Studio with 32-core GPU + 64GB RAM + 1TB ROM SSD. Comparing with a sine wave generator, I found that this unit is bound to be annoyingly noisy at 2021Hz. However, I’m now pretty sure that the high frequency whine is coming from the unit’s fan and not the resonance of the inductor coil, as its frequency varies with fan speed. And expressed his opinion, for a device with such a high price tag, I really can’t accept that Mac Studio can let such quality control flow out. MacRumors points out that the M1 Max and M1 Ultra have different heatsinks, which could explain why the other configuration didn’t have the same problem. But the M1 Ultra model has more luxurious radiator materials, so the fans are activated less frequently during daily work.
Of course, not all M1 Max versions of the Mac Studio are unusually noisy, with some customers simply complaining that the fan is too loud at full load without the annoying high-frequency whine. Apple said that if this happens to users, it is really unbearable, and they can go to regular retail channels to provide a one to two-week “no reason” return period, but there are also reports that the replacement machine also has the same problem.
In view of this, users who are afraid of trouble should try their best to order through Apple’s official channels to ensure better after-sale return policy support. I would like to remind users that if they are not in a hurry, they can wait for Apple to officially solve the problem before purchasing Mac Studio. As for whether the software is poorly optimized or the hardware itself has problems, it still takes time to test.
