MacBook 16-inch Fan Noise

I really loved my ipad but it became useless quickly because of the planned obsolescence

Your devices continue to be able to do everything they could do with them the first day you used them. Apple has added additional capabilities as well, for free!

It is not 'planned obsolescence' that makes these devices less useful to you, it is your own increasing expectations for ever more features and functions.

How do you use a DVI to DVI cable when that Dock has only DisplayPort and ThunderBolt-3 Display outputs?

Far from the truth and if you believe in this fine by me but discussion on this subject should not be part of this thread. I apologize to everyone that is actually contributing in solving this issue. I love my MBP16" it just have one annoying problem and it made me a hater now which I truly am not. I made a bet on apple by investing in it like we all did. I believe this puts us on the same side and I hope apple is there with us.

Let’s try to keep this discussion on topic, your post is not related to the MacBook Pro 16-inch overheating when an external monitor is connected.

On a side note, at least you can update those phones, good luck trying to update an android phone after 2/3 years....

Dear Apple Support Communities moderators.

I would like to thank you for your part in supporting this community, in which Apple users are able to come together and discuss their concerns and issues. I believe this is an important part of being an Apple owner: to compare notes and support one another, as well as to build trust and confidence in the Apple brand and its products. These communities work best when discussion is relevant, courteous and productive.

It is with some regret, then, that I ask for your help in restoring that good community spirit to this thread. There are a small number of posters in this thread who have been making frequent posts that are not relevant, courteous nor productive, but appear to be designed to antagonise. This has had the disappointing effect of generating a large volume of annoyed responses from legitimate posters who just wish to discuss the nature of their concerns in this thread. It becomes very difficult for the forum to support its purpose, as the genuine content is significantly displaced by these disruptive comments and the responses they generate.

Unfortunately, the forum tools do not allow me to flag inappropriate posts, so I hope that this post will instead serve the purpose. I, and my fellow community members would greatly appreciate it if you could intervene and restore the cordial spirit of community that we all come here for.

William Kurchaski's posts stand out as perhaps the most frequent example of unwelcome antagonism.

I look forward to your support.

What “planned obsolescence?”

That's a great example because it literally is not planned obsolescence, it was Apple believing people might want their devices to run longer and slightly slower rather than just summarily power off if the battery draw got too high.

Silly Apple. 🙄

What's the point of discussing anything here, anyway? There's a problem. I have that problem, too. But this thread is 83 pages long already. What's the result? There's a lot of people with a problem, there's a couple of ardent Apple defenders who are tough on the unwanted posts. There's no solution.

So not sure if this is another bug but further evidence of the GPU misbehaving, after disconnecting the external displays from my MacBook the radeon high side remained running at 20W when playing a YouTube video in safari.

After restarting and running the same video it's happily running at 5W.

Spin this one apologists 🤨

I meant DisplayPort to DisplayPort - you can substitute DVI for DisplayPort each time you see it in my post. My bad.

Thanks for that.

The primary performance difference between HDMI or DVI and DisplayPort family is that HDMI and DVI require the "heartbeat" refresh, required for old Analog CRT displays. If the entire screen data are not supplied every refresh period (like 60 times a second) an HDMI display may blank the screen momentarily, causing it to flicker.

To get an HDMI (or very similar DVI) signal out of the computer, the adapter signals to the computer port to use DisplayPort Dual Mode DP++, which switches to HDMI/DVI timing and asks the computer to send the heartbeat screen refresh data. For a large screen, that is a LOT more data.

DisplayPort displays have a screen buffer. DisplayPort sends only the changed data in most cases, so when the screen stops changing, the link goes quiet and we expect (but do not seem to be getting in this case) the generated heat to be reduced.

I'm also seeing some other strange behavior, I don't know if it is related or if other people see this, but, when waking from sleep often the monitor is fixed at a very low resolution. To resolve it the monitor needs to be rebooted, issue didn't happened with 15'' MBP and same monitor.

You should not have to re-boot to resolve this.

Historically, to get a Mac display to become active, you need the Mac to query the display, and the display to answer with its name and capabilities. Otherwise, the display will not be shown as present, and no data will be sent to the display.

This query is only sent at certain times:

• at startup

• at wake from sleep

• at insertion of the Mac-end of the display-cable, provided everything on that cable is ready-to-go

• on invoking Option-(Detect Display) button in Displays preferences

so try doing some of those things and see if the display comes alive at the correct resolution.

Allow me to join the choir – my 16" MacBook Pro gets annoyingly loud and is virtually unusable when connected to a 4K display, either via HDMI adapter or CalDigit TS3+ dock.

Fans start spinning almost immediately, but that's not the worst part. The worst part is that under load (mostly photo/video editing) with 4K display connected, my laptop quickly heats up to over 95 degrees C and slows down to a crawl.

I have a Core i9 model with 32 GB of RAM and AMD 5500M and I was expecting to use it as a desktop at home and as a laptop on the road, but it's just not doable. It gets incredibly hot and slow during long photo editing sessions when connected to any 4K display. When it runs on its own it gets loud, but at least it doesn't throttle Unfortunately, since I need a monitor with accurate Adobe RGB coverage, I cannot use MacBook Pro on its own at home, I need my 4K display. I've tried everything to remedy this issue and nothing works. My last resort is to try an eGPU and see if that would take enough load off of internal GPU, but come on – that shouldn't even be taken under consideration with such a powerful computer.

I was also thinking about getting an eGPU - but then what is the point of having a machine that already has a supposedly decent dGPU if you are just going to bypass it, it's a waste that is what it is, yes?

Exactly! And what's more – as this video shows, it's absolutely not worth it: https://www.youtube.com/watch?v=GjOdBH9QgrQ

The sole reason to get an eGPU is to combat those overheating issues. And that's simply ridiculous.
