MacBook 16-inch Fan Noise

You can see which GPU is being used when you click on about this mac from the apple icon in the top left hand corner of the screen.

You'll see the radeon 5500m show up when you plug in an external monitor

Sadly, he doesn't know that the dGPU is hardwired to be the only graphics option available when connecting to an external monitor. That is evidenced by the wattage and temperature of the Radeon High Side and Radeon GPU proximity sensors for each respectively.

I wish it were true, but, no...

I don't have one at moment to check how it worked.

I don't know, if it's relevant for the problem here. But my 2013 15" MacbookPro Retina Dualgraphics has the same noise-problem since updating to Catalina. My Workaround is to set the monitor refresh rate from 60hz to 30hz. Fan spinning then nearly unhearable.

I have just talked with Apple support. They could not tell me if any improvement have been implemented in relation with the defective fan system at MBP 16.

They just recommend to order a new one and if I am still not satisfy, to return it.

What do you thing about that? Is it worth to order a third one?. Or should we just to throw in the towel and forget about to order further MBP also forget the issue?.

Nonsense. I recommend this machine in a heartbeat. Not everyone connects their MacBook to an external monitor and furthermore not everyone using an external monitor is experiencing noisy/loud fans just from some of the posts here. I won’t comment on my experience because when someone here says they aren’t having issues with an external monitor it’s not good enough. Some others request even more extensive testing just so they can be right.

I’ve asked you three times to just test it with one UHD monitor plugged in with the lid up. Still have not seen your response.

Is that extensive testing? Or are you just here to minimize the trouble we are having.

mine whines up to 4500 - 5000 just from sitting idle for a while. Not right.

Maybe you will give it a try sometime? You seem willing to participate here otherwise.

I would like to use for sure with an external monitor.

It makes no sense to just use it without monitor, only on the go. At home is clear goes with an external Monitor.

This is really frustrating, one customer angry means that several customers around would have also bad communication of the product.

The time is passing and the image of Apple is deteriorating.

I don’t know how long we need to wait.

REALLY FRUSTRATING and DISAPPOINTING. And it used to be the best company ever. INCREDIBLE.

Apple, we are waiting for a solution.

“It makes no sense to just use it without monitor, only on the go. At home is clear goes with an external Monitor.”

Ridiculous! The majority of the world uses laptops at home with no external monitor. I have no idea why you think what you said was logical because it’s not. Laptops have screens of their own. They don’t need external monitors.

“The majority of the world”, if this phrase is not speculation, then my MacBook Pro is not overheating when connected to an external monitor.

All the people I know that got a MacBook Pro, it was to be able to use it as a portable and desktop computer and all of them (including myself) use it with an external monitor, keyboard and mouse. So if that’s the case, I can’t recommend this computer right now.

Me also.

Most people that I know don't use desktops anymore rather they have laptops and use them plugged into monitors when at work or home. You can't really beat extra screen real estate with most work flows these days be it programming, video editing or most things really.

““The majority of the world”, if this phrase is not speculation, then my MacBook Pro is not overheating when connected to an external monitor.”

Yeah and that’s no worse than people saying here “This issue affects all MacBooks”. “Everybody has the problem, they just don’t know it”. SMH.

This is like saying "not everyone drives on highways therefore it's not a problem if a car is extremely loud at highway speeds".

Enough people do, the majority of people probably do, so it's irrelevant.

Apple runs a real chance of losing the pro-crowd with these shennanigans, but maybe they don't care because there's enough posers buying into the 16" for the brand who don't actually utilise their laptop for what Apple claims it's intended for.

^ typed on a macbook pro 16" connected to external monitors with fans blaring at max RPM because Chrome on its own is an extremely intensive workload apparently 🤣

<< because Chrome on its own is an extremely intensive workload apparently 🤣>>

that part of your statement is indisputable.

Chrome has always been more resource-intensive than any other Browser, and Google has been in no hurry to improve it. Meanwhile FireFox and Safari are now Faster, better, and far less resource-intensive than Chrome.

Executive summary:

Chrome is a pig -- dump it.

My $2500 thin'n'light gaming laptop with similar specs and a better GPU than my 16" pro seems to handle it just fine, no blazing fans or anything.

Perhaps instead of focusing on an innocent browser we turn our attention to an extremely expensive laptop that is sweating and overheating while running it? 😊

Executive Summary:

MacBook Pro 16" under no load
