MacBook 16-inch Fan Noise

You brought up Chrome, as if running Chrome as implemented for Macintosh was nothing.

I could not let that outrageous statement stand.

What's outrageous is claiming a browser running an online forum should cause a laptop to overheat.

But It looks like everyone with over 10,000 points around here are in the busines of defending Apple than trying to find solutions to glaring problems.

LOL agreed. I can have 0 applications open with a second monitor hooked up and it's still overheating with fans blaring. Using chrome is fine on mac and it's insane to say otherwise.

Google Chrome is not a good example, because it OFTEN turns on the Discrete Graphics chip, which is thought to be the cause of everything on this discussion.

If you want to make this argument, please use a different Browser as your example, or this will-xxxx

... already has ...

deteriorated into a name-calling flame war.

If you clicked the link I literally posted in response to your comment instead of trying to formulate yet another weak argument to justify the horrible thermals on the MacBook you would have seen I did you one better,

MacBook Pro 16" running on idle with fans on fullblast: https://www.youtube.com/watch?v=pJT660pUOMc

No browser to speak of.

There is no flame war, there is you an dall the defenders who are objectively wrong and unhelpfully trying to defend this abnormal behaviour as if it were normal, and there are frustrated people like myself trying to find a solution.

I understand Chrome can be a resource hog, the thing is it will run fine at a cool 40c when using the dGPU + internal screen, however plugin an external monitor and the heat will go nuts, something is wrong there.

I am not defending this abnormal behavior as if it were normal. No one has done more than I have to determine the exact conditions under which this foolishness occurs, and urge Users to do the most effective things to get this situation fixed.

Perhaps you have confused me with someone else.

I am merely suggesting that if you cite an example, it should be relevant.

It overheated? Do you have a photo of the screen showing your MBP 16 notifying you it is shutting down to cool?

In fact, the fans running is a sign it is managing the thermal load properly.

You can of course argue whether something should be generating so much heat with that load, but the laptop is not “overheating.”

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.

I don't understand why you people refuse to look at my video.

Here it is again: https://www.youtube.com/watch?v=pJT660pUOMc

Literally CPU is under 1% load, the temperature is at 55, there is nothing running it was from a cold boot.

Please watch that video and then I expect a prompt apology and acknowledgement of a defect.

If you are actually arguing it's normal for a laptops fans to be running on full blast after a cold boot then your opinion means nothing.

But you are also the person who was attacking someone for returning their broken macbook pro because it cost Apple a sale, then argued he should have bought an iMac Pro instead.

I'm done with you, I tried to be civil but it's apparent you're just here to be an apologist, I'm honestly very dissapointed in you because I thought you were making reaosnable ponts and when they were countered by othe rpeople making valid points you dug in deep instead of acknweldging there is an actual problem.

You went from "as long as it doesn't thermally shut down" to "well you should have bought an imac pro".

Even the Apple technician I sent my MacBook to acknoweldged there's a problem and is now ordering a replacement logic board.

If it puts your bleeding Apple hearts at ease the issue is CLEARLY a software bug or a hardware issue on the part of the radeon GPU which draws an abnormably high 20W when powering multiple displays, when it's just powering one it runs at average 5W.

Apple really needs to make peace with nVidia because AMDs GPUs are always causing people problems.

I completely agree. This computer is great and is the best MBP I've ever owned in many ways. There are a few people experiencing overheating issues, but mine is not one. The biggest problem I seem to have is it's tighter in my backback than the 2019 15".

I've ran the test that people have asked and it always comes out fine. The fans turn up when it gets warm and cools down quickly when it's done working. It doesn't matter if it's in clamshell mode or not, connected directly to multiple 4k screens directly or through a dock.

If you are having problems, return it until you get a good one. I certainly wouldn't trade mine.

Did you connect the external monitor directly to the computer or using a dock?

because mine is connected directly with a close lid and the GPU is drawing 20 watts and the fans run really fast.

we have 5 more 16-inch in our office and all of them have the same problem, so I don’t think returning the machine and getting a new one will help (I can’t return mine anyway,

it’s been more than a month).

i agree with you guys that if you don’t have the machine connected to an external monitor it’s an amazing machine that can handle a heavy load and stay really quiet, that’s one of the reason that I think that I think that is not normal what is happening when you connect an external monitor.

I’m not sure who you think I am but I never attacked someone for returning their MBP and in fact advise it if the fans are going to bother you.

I did however recommend if you are going to use your MBP with an external display most of the time an iMac Pro or Mac Pro would likely serve your needs better.

Even the Apple technician I sent my MacBook to acknoweldged there's a problem and is now ordering a replacement logic board.

Did they, or did they order one to attempt to assuage your concern?

I think there should be some moderator here. This thread is not about overheating, but fans speed and their noise while connecting external monitor. I think this issue occurs just to prevent overheating. The question is why external monitor connection brings such behavior. There is still no answer and no solution from Apple. End of story.
