MacBook 16-inch Fan Noise

What happens if you put one more monitor ? The fans will go loud ... really loud.

With an external GPU I can still use turboboost without any fans noise. 5000 $ machine you should be able to use turboboost sorry.

Apple is not here. This is the Apple User-to-User Support Community.

This medium excels at brainstorming divergent solutions to Users problems. We have no standard method for problem escalation to Apple Engineering.

Your method for that is to use the "get support" link at the top of every forum web page.

Thank you for your update. Two more questions :)

Have you checked what's the power usage on "Radeon High Side" when running a monitor/two monitors via DisplayLink Solution?

Does your 34" Monitor run with 4K@60Hz?

There are 266 pages on this topic. My fan on my top of the line MBP (32G and upgraded GPU) runs fairly consistently even when doing basic tasks such as Spotify, browser, slack and a mail app. It's obvious that this is the reason why Apple has ditched Intel, but what of the people who own these computers? Is there no fix outside of buying a new M laptop?

I have a MBP 16” from July 2020 with 64GB 4TB SSD and 5600 m and within 3 weeks had issues.

So far the problems are -

1 - Crashes and panics related to the PowerPlay failed to resume or initialise - Specific to AMD internal / External GPU

(This is when the machine comes out of sleep or on shutdown or under high load)

2 - Load fan noise and 98 > 99 degrees C for no apparent reason

3 - When all 4 ports are in use KERNEL_TASK renders mac unstable then freezes and crashes.

4 - Sudden battery drain for no apparent reason.

Several other issues that where inherent to catalina they big sur has mostly eliminated.

It all depends on what you are doing and of course your monitor.

I can remain connected to my Dell U2717D via mDP all day and my fans never actually spin up.

Now if you're doing something very computationally intensive at the same time, that may also make a difference.

The two 15s don’t have anywhere near as powerful a GPU as the 16.

I use my 16 regularly with an external display attached with no issues, it’s all a matter of what you are doing and with what external display.

I’ve also mentioned it’s trivial to get Windows laptops to do the exact same thing if not worse; I can get the fans to ramp up to full on an HP Spectre x360 laptop with no external display connected just by entering the Windows 10 Settings pane.

The specification page claims that it can run up to two 6K displays simultaneously. Doing this (and also using displays with a lower resolution) produces so much heat, that the CPU may get throttled—besides the noise that some people are able to ignore but impairs others strongly.

Also I would think that when you advertise a product being capable of running two 6K displays, connecting two displays is not a sole objective, but a precondition. You don’t connect one or two displays just to look at them being connected, right?You want to work with them. So connecting an external display should not limit your ability to work with your laptop.

Hmmm... it runs hotter because it's more powerful and the MacBook Pro is thinner than the mid 2015 one!

But do you hear the fans? that's the only concern.

with a eGPU , I don't hear the fans at all except when doing video encoding.

Right now I'm working on a very demanding project on Logic Pro, and my fans are consistently running around 2200 RPM, which's almost silent to me.

As I posted earlier, that is exactly my experience and the reason I came to this discussion group.

After detailed testing, resetting, and hours on the phone, Steve from Apple Support told me that it is normal behavior and he refused to give me anything in writing. So, it is "good" to hear this from others.

My Posts often got deleted from Apple because of what I am writing...

hope this stays long enough before the Mod is taking it away...

APPLE KNOWS THAT PROBLEM AND THEY CAN NOT FIX IT !!

they keep it "low" and don't talk about because of Bad Press and lawsuits

that's the reason why they keep it confidential and say there is no issue.

just believe me when I say, I know that.

I hope for the new 16" MBP, I have since weeks the MacBook Air and it runs super powerful - don't even noticed a fan

bought 2 x 16" MBP in the last 16 Month for 15k € and they're unusable for location work - even without a 2nd screen when you run Logic its so ****** loud. The specs, speed and power is a dream but not for a laptop.

And I am not the only one with that "problem". Everyone around me has that problem.

The CPU and GPU draw generate a set amount of heat, and the fan works to cool down the interior for the amount of heat generated.

Yes but the issue is that they should not generate such an amount of heat only to display something on a external display... Even the integrated GPU could handle could handle it, if only hasn't set a rule "external display = dGPU".

Please remove your blinders ;)

And why does the issue disappear has soon as I use it in clamsheel mode?

The dGPU not longer has issue with the refresh rate?

Some people has already tried to use SwitchResX to slighly reduce this rate, it works in clamsheel mode but not as soon as you use again the laptop internal display.

Why a laptop so expensive cannot deal with something that so much cheaper windows laptops handle perfectly?

It is like telling to an overpriced Audi's driver that he cannot cruise on the highway at the same speed than the guy with a cheap car without overheating its engine, when the other car can.

Explain an issue doesn't legitimate it to my eyes, not at this pricetag.

What has been relayed to you is what AMD has said on other forums regarding their GPUs:

It's still not a bug though.

Multiple displays with different resolutions, refresh rates, timings and or using different display adapters/connections requires more resources from the GPU, this can move the GPU up into the next memory clock state to compensate and avoid issues such as flickering or corruption.

If all displays are identical, using the same resolution, refresh rates, timings and using identical display adapters/connections then the GPU may be able to run two or more without moving up into the next clock state. It can vary from Bios to Bios and GPU to GPU, but the expected behaviour is increased clock speeds so this is not something we can change.

You can feel free to accept it or not, but they're the ones who would need to make any changes and they feel it is working as designed.

Price points have nothing to do with it.

Note also the dGPU only drives external monitors and the onboard GPU drives the laptop screen, so clamshell mode shuts off the internal GPU, reducing the heat generated somewhat.

Those "much cheaper" Windows laptops don't have anywhere near as powerful a GPU.

I work with a office's tasks oriented 700€ laptop all week, he manage perfectly 2 external full HD screen without noise and is just a little bit warm.

The few times, I used my personal MBP 16 instead, for exactly the same use, it is much more warm and the fans start frequently.

As a consumer, I don't want to have to understand VRAM issues or something else, I just want to have a least the same experience with my overpriced MBP than the one I get with my simple plastic Lenovo laptop when I ask him the same things.

I thought I wasn't asking for the moon...
