MacBook 16-inch Fan Noise

if there is a problem I have a right as a costumer to use all the available channels to get it noticed.

Your only effective recourse if discussions with other Users do not solve your problem is to Contact Apple Support.

If Apple had people 'working' the forums to collect and solve problems, do you really think they would do so invisibly?

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.

Maybe it's just a lot of people who bought the new MacBook Pro 16" because it was what they were looking for and found the issue? There actually is nothing comparable to the 16" MacBook Pro out on the market especially for pro use.

And I wouldn't be surprised if most 'pro' users like myself use multiple monitors for their work, so it's kind of a natural thing to happen a lot of Apple newbies are getting into and as power users are having the same issues.

I also have Macbook Pro 16 with the AMD Radeon Pro 5500M 8 GB and I'm also experiencing the same issue when connecting my computer to an external monitor, I spent some time reading most of the comments and it seems that a lot of people is having the same issue, saying is not a hardware or software issue at this point is crazy. I read that some people is saying that this is normal, I'm sorry but I work for a studio that has more than a 100 Macs all from 2015 to 2019, no other machine is having this issue when connected to an external monitor, and if just connecting a $5000 "Pro" machine to external monitor causes the machine to heat that much, I don't think they should call it Pro, and the worst thing is that the CPU and GPU usage is less than 5%, so that doesn't make any sense, and if I do way more intensive tasks (for both the CPU and the GPU) without an external monitor connected, the machine is dead silent so obviously it can't be normal what we are experiencing.

Other forum post quote:

"FWIW, there are absolutely AMD 5XXX series driver issues with macOS Catalina 10.15.2 which are repeatable with both 5500M and RX 5700 XT in eGPU, especially when it comes to METAL. Additional reports in the MacPro forums with MP7,1 using RX 5700 & RX 5700 XT with the same issues. Personally really hoping Apple (and AMD?) address the driver issues before W5700X is available. Guessing 10.15.4 until it's really worked out, but 10.15.3 really should see an improvement if they're working on it."

Hi Tim

I must have missed your earlier post about this issue. Yesterday I tried it at different scaled levels on the internal screen and it seems to be an issue at all of them, for sure it was happening at the default level on the internal and external display.

The strange thing is that right now I can not replicate the problem on any scaling level! Yesterday it was happening all the time when I was checking. I wonder if it is only happening when the system has been running for a while?

Would trying it in safe mode be the same as a fresh install? I'm not sure I have time right now to do a fresh install. Do your replaced MBPs still have the thermal problems?

Just had a very lengthy chat with Apple Support explained everything around this issue. Stated the temp difference before/after connecting to external monitor, also the AMD GPU power consumption caused this.

They are taking it to the engineering team

Just because they happened to contact you due to this thread does not make Apple Support Communities a viable way to reach Support.

It’s a little like if your house catches on fire, and a fire truck driving by notices and stops.

It’s great it happened, but it is not the recommended way to get help if your house catches fire.

On the other hand I am happy the Apple Business Team is working with you and some others here.

"Not sure why anyone would be spending time in this thread if you are not experiencing the issue or if you don't not own a 16inch MBP. "

Firstly, don't make incorrect assumptions. I have a 16" MBP. Core i9 2.3 Ghz 1TB SSD 8GB 5500M 32GB Ram. Secondly it's ridiculous for you to expect people who don't have problems not to post. It's just as important for people that don't experience such issues to post otherwise the wrong information gets put out such as people saying the issue is "widespread" just by looking at all the negative posts. Everybody who owns a 16" MBP should post if they prefer to. Your post stating that people not having problems shouldn't post is just as bad as people stating that only good things should be said without criticism.

Also for your information my eyes work 100% perfectly. I don't need to read posts towards me using all caps. You can emphasize your point perfectly without using caps. That's yelling.

DPJ:

You have my exact configuration. If I missed it, I apologize, but have you tested your setup with one monitor plugged directly into the machine with a display port or HDMI adapter with the lid open? If you could please do this with turbo boost enabled, I would appreciate it.

If you have, would you please confirm what you experience for us?

You are 100% welcome to be here, whatever your purpose or intent. I would personally like to know if you have this issue when you are connected as I outlined above. I can't avoid the high heat and loud fans whenever I run mine in this configuration.

That would be really helpful - the more people that can check for this issue we can see how widespread it is.

I have not heard of anyone that has not got a problem when testing in the situation you have described.

Again, using an eGPU, Clamshell Mode or only the internal monitor is not likely to cause the problem with excessive heat or power when the system is mostly idling.
