MacBook 16-inch Fan Noise

More efficient?

Do you know the definition of that word?

“Achieving maximum productivity with minimum wasted effort or expense”

“Preventing the wasteful use of a particular resource”

i think this is definitely not the case for this machine.

No, the MBP 16 is a four-cylinder, a 2019 Mac Pro is the V8.

Previous generation MacBook Pro's are Yugos by comparison. They don't have anywhere near the GPU capability that the MBP 16 does and don't produce anywhere near the graphics throughput that the 16 does.

It doesn't make a bit of difference what the fans do except it annoys some in their use cases.

For all the people here saying that there is no proof that the overheating (or heating more than it should, to avoid any issues with the overheating word), every day more people is posting here and on different websites problems with their GPU, kernel panics, weird sounds from the fans and today I have to add a new one, I always connect my external monitor to the same USB-C port, today that specific USB-C port started failing (check the attached image), coincidence? Maybe, but after seeing all the issues related to this problem I'm pretty sure that it was caused by the high wattage when connected to an external monitor. If I connect the external monitor to another USB-C port the screen goes back to normal, how long until the other USB-C port start having issues... we'll see.

Incorrect. My monitor is g-sync and not freesync. So unless AMD now supports gsync (which I don't think is the case) it's just a static 160hz refresh vs static 60hz refresh that reduces power consumption by 4x by loading gpu 2.5x more :). Reasonable guess though.

FreeSync is an adaptive synchronization technology for liquid-crystal displays that support a variable refresh rate, aimed at avoiding tearing and reducing stuttering caused by misalignment with content's frame rate.[1]

from wikipedia

I wrote "freesync" in quotes. I intended to suggest ANY technology that allows the uncoupling of row refresh speeds from the strict requirement that the data must be present at exactly the correct time or the row would be blanked out by the display hardware. DisplayPort displays already uncouple this refresh, and other methods may also allow a similar uncoupling. This may, in some cases, reduce the RAM speed requirements, which could reduce the requirement to run the RAM at full speed, full power.

I would also like to point out that screen refresh as high as 144 Hz is not possible using ordinary hardware, and when you select such high settings, you are counting on the display to provide that refresh speed using its own internal screen buffer.

Grant - Great post. I understand that a number of factors are involved in this issue, and hopefully Apple will correct the defect soon.

In order to mitigate this, I am going to purchase a new monitor with a higher refresh rate (1440p, 144Hz, 120Hz, 100Hz); does it matter which refresh rate you use, provided it is over 100Hz? I have seen a few posters here (I think it is iTech) who said he went up in refresh rate and dGPU power dropped to 5-6W.

Is there any particular monitor setting/type that would perform better than any other, just based on this idea?

Hi Tim! Hope your day is going great! 😊. Everyday I see new accounts created here with no avatar. Some refer to these as "Ghost Accounts". They post that their 16" MBP connected to an external monitor is overheating, defective, no good, junk, etc, along with ranting. I've never once ask any of these people or anyone here to show proof, nor does anyone else here ask that of them, hmm. Because it's not required of them. This is only a discussion forum. When I make posts I'm not looking for anyone's approval, nor am I asking for anyone to believe me. That's on them. At least my Avatar shows my 16" MBP that I use to run my business daily, as opposed to blank avatars.

"At the same you say Apple Senior Engineers should never contact a customer back when gathering data related to problems. Apple should never acknowledge there is a problem and work to resolve it.

If this isn't bias, not sure what is."

Ah this interesting because I went through ALL of my posts and there's nothing here posted by me of any of those words. I never said one word of this. Not sure where you got that from. Please show proof? 😊. In fact I've said to members to contact Apple support because many people seem to think that Apple is playing Big Brother and is reading these forums. The notion here seems to be that Apple should instantly ADMIT something without collecting enough information directly from customers. Any sane company will work with customers directly and WILL fix things if enough customers reach out to them directly to a point that they can't ignore it. That's what I've been saying. So either you read someone else's post and got mistaken thinking it was mine or you're making stuff up. 😉. Have a good day!

This is not a "free speech" zone, you must adhere to the Apple Support Communities Terms of Use to post here and agreed to adhere to them when creating a login.

Accordingly, moderators can and do remove posts that violate those terms.

"Why would he contact Apple Support if they are not obligated to verify, acknowledge or fix the issue?"

Because during the warranty period Apple IS obligated to do a hardware test. If they find a defect they will fix it. It's in their warranty terms. You're confusing obligation with admission.

"But technician guy I spoke with said that I'm not first person who have problems with 16" macbook with i9 CPU and for now there is only one solution - wait till Apple will start a recovery program which will happen when there will be a lot of people with problem."

"He also suggested me to install Mojave and check if problems are solved using this macos version. "

So you actually spoke directly to Apple Support telling you all this? If this was actually Apple I'm certain the technician would know that it's impossible to install Mojave on the 16" MBP. 😉

Apple sells and tests with ThunderBolt and DisplayPort displays. There is no HDMI port on this computer.

Try a DisplayPort family display. You might like it.

That is a bit rude, you're making assumptions Pal, I am using DisplayPort.

I am still waiting for your explanation why computer running 160hz on the same monitor draws 4x less power than when 60hz. Monitor and connection type the same. Only difference is monitor refresh rate. Having 2.5x higher refresh rate (and therefore load on the hardware) results in 4x lower power consumption and therefore 10-20 degrees lower computer temp. Thermal shutdown is marginal case and is far from being only criteria for something to run hot. P.s. anyone old enough still remembers AMD cpu's being caught on fire without thermal shutdown happening ;) Or was that case not defective as well, because they would never shut themselves down?

And yet you claim that computer that is capable of consuming 5w and running silent is expected to run 20 degrees hotter, die 2x faster (because of empty battery) and keep its fan at full blast while idling on at at least 2.5x lower load while idling, right?
