MacBook 16-inch Fan Noise

I have not tried messing with the fan profile and I don't think I will, I'm not sure that it's safe to do and I am pretty sure that Apple would not recommend it, could it even void the warranty? The thing is the machine is getting really hot the fans aren't just spinning up for a slight increase, reducing fan speed will just increase the temperature and could potentially cause damage. Some people have already seen graphic issues and crashes when it gets really hot so I don't think that should be recommended, it's not fixing the core problem.

Getting an eGPU is a workaround it's not really fixing the problem.

Turbo Boost switcher is probably a good idea if you want to push your CPU conserve battery and keep the heat down in that situation.

And before someone explains to me again for the nth time connecting a 4 or 5k monitor is a such GPU intensive situation that it causes massive heat and GPU power consumption. Well how come a tiny fan-less $120 mini pc with windows 10 can do it without a struggle?

With nowhere near the performance of the Radeon Pro GPUs.

Exactly, and they do it with nowhere near the supposed efficiency and power savings of the Radeon Pro GPUs.

To be honest, without using an external monitor this machine is very good it can really do things quick at a decent temperature. I would be very happy with it if I didn't need to plug it in to a monitor.

The video is interesting, and it is impressive how far they went with trying to find proper solution. However, in the happiest scenario where these remedies work, it is just work arounds, not solution. None. Expects to buy $4K+ machine and then look for third party hacks to bring it to behave normally.

And to make things clear to avoid the unwanted argument, most of us (if not all) are complaining about the unjustified fan noise when the machine is idle.

" Expects to buy $4K+ machine and then look for third party hacks to bring it to behave normally."

The behavior in the Windows world every single day of the year and for some unseen and ridiculous reason those Windows users tolerate it and never give up. A fan in the MacBook that actually cools the machine to reduce/eliminate throttling is trashed by some users here as if a crime was committed by Apple. Asking for help here is what this forum is for and there are a great deal of people willing to help, but coming here and starting up new accounts (which happens daily here) simply to trash Apple and combat anyone who has a positive word to say and is not experiencing these issues is not what this forum is for.

First, I am not windows user! Secondly, guess what, many cheap laptops works out of box with preinstalled windows without such ridiculous noise!

thirdly, I did say it is great effort that people went that far to find a solution; however, that doesn’t put Apple in any better position; it us actually a shame that they didn’t do their job so we don’t have to be in such thread.

Lastly, you are the one who didn’t read my entire comment and don’t acknowledge that there is a problem and like the other two who are here entirely to argue with no point.

I don't think you fully understand the problem that people here are experiencing. It's fantastic that you have a perfectly functioning computer but why dismiss others that don't, it's not constructive or helpful to anyone.

It would be great if people would be more understanding, why come and comment on an issue that they have no experience in and being so un-helpful, what is the point in that?

I am also noticing very high GPU time for WindowServer, I posted a screenshot earlier, it was over 100,000 hours. It really looks like something is wrong with that, it's not normal is it. Has anyone else noticed this?

Today the CPU temp went up above 90c with the CPU IDLE at about 98% I restarted the unit and with the same apps running it's at 70c - still hot - no explanation as to why it rose to above 90c when doing nothing.

BTW it seems my screenshots showing high GPU time were removed with no explanation.

This is a User-to-User forum, Apple is not here.

That number is the total GPU time on either GPU since your last restart. It does not look like a problem to my eye, unless you have recently restarted.

If your screenshots contained personally-identifiable information, such as your serial number they could have been removed for that.

Generally, when posts are removed, you get a note from the hosts with at least the category of reason why it was removed.

I have no idea. That parameter is fairly new and I have no idea how its is computed, except to say that it is likely the sum of all GPU time on BOTH GPUs useless otherwise broken out.

Whether that number is accurate is the least of our worries on this thread.

I have been been answering questions here since about 2001. I have never seen an example where Engineering picked up first report of an issue from the forums.

To the best of my knowledge, no one from Apple Engineering or Marketing has 'reading the forums' as part of their job description.

More recently, when I tried to get forum management to push this 16-in MacBook Pro fan noise issue along to Engineering, I was told that Engineering had declined to receive even pre-filtered information from the forums, and senior contributors were urged to tell Users to "Contact Support".

It is far more likely that your support person mistakenly generalized a single interaction where Engineering reached out to a single poster, ONCE, as "they always do that".

You seem determined to miss the valid points raised by users here. The fan noise occurs when the machine is not being pushed, it seems to overheat for no reason at all. The fan noise is a by product of overheating for no reason and is also very annoying too. One of the reasons I use Macs is that they are usually very quiet. When I took my 16" back to the Apple store to be checked out, the technician said it's certainly not meant to behave like that.

What is counterproductive here, is people who do not have the issue come on to try and make out that Apple is perfect and we are imagining problems. Plus the only people complaining are Apple users and it's specifically because they have a duff product. Some who may have recently created an account because they now have a problem they need help with or are new Mac users.

Also the main difference between PCs and Macs is that the hardware and software with pretty rare exceptions are made by different companies. And PCs are usually a fraction of the price.

“ Some who may have recently created an account because they now have a problem they need help with or are new Mac users. they now have a problem they need help with or are new Mac users.”

I’ve never once made Apple to be perfect. What I have mentioned is every new problem filled with comments saying they have the same problem are 100% all new accounts. Some will see that as an hidden agenda to grab the attention of the company. Saying that the 16” MBP is overheating with loud fan noise and doing absolutely no tasks is something I’ve never experienced. Therefore it leaves the fact that your machine is faulty and it’s not an issue unique to the 16”. Obviously your machine is defective.

"Saying that the 16” MBP is overheating with loud fan noise and doing absolutely no tasks is something I’ve never experienced."

Have you even tried checking it with an external monitor, because that is what is causing the issue here. You can't say you have never experienced the problem that the majority of people on this thread are having if you don't test it in a similar situation, it's very basic logic.

The fact is that not everyone uses an external monitor but a lot of people do.
