MacBook 16-inch Fan Noise

Fo you work for Apple, William?

I think your claim that the logic board order was a “just in case’ measure is speculative.

Nope.

However over a decade of experience here at Apple Support Communities has seen Apple Store techs order parts to try to fix an issue to ensure customer satisfaction quite often.

I've never run an external monitor, but I just hooked my 4K TV to the AV Multiport, set it to 4K 60Hz, and have been using it as a secondary monitor to playback the viewer in FCPX for the last 5 minutes...silent as can be, absolutely no fan noise. :-\

Mine gets hot after 30 minutes or so, even if I’m not doing anything with the machine (other than having the external monitor connected), it also happens if the machine is with the lid closed and in sleeping mode.

I've also noticed mine stays quite warm while asleep (no screen saver), the previous MBP would remain cold and I just left it on 24/7 for weeks. This new one I've got in the habit of switching off each day.

That IS an external monitor, as is a projector.

If you are NOT hearing load fans, that suggests there may be a Hardware problem with some of the Early samples of this product.

¿What version of MacOS?

I once left mine with the fans blazing for a few hours plugged in and it was still blazing the fans, can’t be good for it 🤔

Why? That means the fans were properly cooling the interior to deal with the heat that was being produced.

If it had gone into thermal shutdown, that would have indicated something bad.

In this case the fans were keeping the interior from reaching the point of thermal shutdown - the very reason they are there.

Conventional desktop PCs are designed such that one or more interior fans are running whenever the system is powered on, and the same is true for most any PC graphics card featuring hardware as powerful as that on the MBP 16's logic board.

If it isn't going into thermal shutdown, it is keeping cool, as designed.

That's why the fans were put into the design.

You don't like when the fans run and how fast they run, and that's fine, but it has nothing to do with the thermal design of the MBP 16, which is working as it should.

As long as it went when I put it in gear without going over redline, why would I care?

It would be working as designed as a car unless it stalled or died.

Don’t like the idle speed, buy something else.

By the way, I didn’t say the fans on high were the MBP 16 were it working as designed, I said the thermal design was working properly.

We don’t know why what is heating up is, but clearly the MBP 16 is keeping the interior below thermal shutdown levels.

William, I do not believe that for a second. Common sense would dictate that you wouldn’t accept a vehicle designed that way.

If Apple doesn’t fix this in this iteration of Catalina, I am going to push hard for an extended return. I use my MBP all the time with the lid open and connected to an external monitor, and shouldn’t have to buy a Razer Core to have my computer not overheat my office while idling. It’s great otherwise.

when I use my CPU heavily, my laptop have shut down, probably happened to me about 20 times since jan 4th? It goes above 100 degrees and can't keep up with fans blasting at full .. Then I have to disconnect my screens to finish that work ..

Working as intended...............

Finding all of this very annoying especially after coming from a late-2013 Macbook pro which had no problems dealing with the same external monitor. It would only speed up the fans in very specific work load conditions (especially video). Used to work in Logic Pro X regularly with no fan noise...

That is not as intended and should be returned.

Mine works fantastic in all the modes I was asked to test and so should others. Yes it does get a little warmer with an exteranl display but still no fan noise.

What? This whole thread with 69 pages and over 700 people clicking "i have he same problem" button is about the fan noise. There is an issue that even the press is talking about. Lucky you, if you don't have the issue. But it is there.

The laptop does keep cool and is virtually silent unless I'm pushing it. If it's not then your MBP does have a problem but most are not exhibiting this issue otherwise there would be 100,000's of users posting here.

100% agreed! People first complained that the 15" was throttling due to poor thermals. Apple fixed that with new fans which are tuned to deal with high CPU or GPU usage. I'm not saying this can't be worked out better but for some people here to use words "defective fans" and "overheating" are putting out misinformation and some want to cause negativity by saying they can't recommend a perfectly great computer just because it doesn't perform the way they want it to. Then if your opinion differs from theirs they end up hurling insults.

BTW the Mac Genius in my local Apple Store took one look at how my 16" was performing with fans and heat and said "It shouldn't be doing that, so best return it seeing as it's new" . The next Apple repair guy who came to sort things out said. "Yup, that's definitely an issue, also the screen seems to be delaminating".

But hey what would they know?
