MacBook 16-inch Fan Noise

Jokes on us, we keep buying these overpriced machines, while the pricetag is getting higher, and their customer service and product quality lower, its not a pro machine anymore its a consumer machine.

Here is average temps while browsing, having slack, skype, twitter and mail open, highest temp 87 C, dont think CPU workload was ever higher than 20%. FAns are basically on 3000 all the time to keep the temps in 60s. I dont even have any intensive programs installed yet as i am thinking this is not a reliable machine and still keeping my old one.

This is my second machine, first got replaced after 1 day, Bad magic kernel panic error. Loosing trust in apple by not responding to the issues, how they can ignore and pretend nothing is wrong where there are hundreds of users with issues.

I have the 5500M 4GB and it seems that it quickly uses up all it's memory, see screen shot. This is without using any graphic apps or even watching videos etc.

Is there some GPU memory leak when using an external monitor with the dedicated GPU?

Is there someway to switch to the integrated graphics and see if the problems still exist?

After I saw your screenshot I connected the external monitor while I was watching a coursera video, in my case the GPU processor went immediately to 100% and stayed like that all the time until I disconnected the external monitor. I know that our friend William doesn't like the word guess, but I'm guessing that by having just 1 tab open with and watching a video shouldn't take the GPU processor to 100%. Of course when this happened the fans went crazy.

I've had mine delivered mid-December, for the first couple of days I had noticed some fan noise.

It was some adobe related problem, I fixed that, and it all went well.

Mine is connected to two monitors both 27", full hd.

My stats are around this while browsing having 6 tabs + one tab with a youtube video playing:

Note: my lid is always closed as I prefer to have it standing on a stand to save some spaces on my desk.

No, I've been monitoring them for a few days now, they're always around 1700/1800.

Even when I fire up my usual development env (VSCode + maybe a node server), they stay the same around that.

However when I fire my app development env (Simulator plus react-native node server) yes they go up for a few seconds, which is normal for me, I had this behaviour on my iMac and my prev MBP 2016.

That's it:

Here is what I'm getting with dual 4k screens connected:

It's in clamshell mode. No fans are running. Affinity Publisher, Adobe Indesign, Adobe Photoshop are all open along with mail, settings, and teamviewer.

I just loaded FCPx with a full timeline and the fans kicked up for a little bit. The fans don't go fast unless they are actually under a heavy load of opening really big files in Affinity or using FCPx . After processing a little bit they went back down to nothing.

If I actively use FCPx it will certainly push up the fans but that's only because it's rendering effects. Once it's done they go back down. It runs so well though that it has no problem cooling and so you don't have the throttling we had in the 15" versions.

Having 2 or 3 screens active seems to make no difference here.

If you have cleared the caches (I'm told that doesn't matter but I believe it does), reset PRAM, reset SMC, I would say something is wrong.

Hello Alek,

Yes, I have 2 4k displays attached and am not having problems (I was having issues with clamshell mode but they were fixed in 10.15.3. See here:

I did an experiment to see if it made any difference:

Both 4k screens connected but now one is directly connected to the laptop:

Next I disconnected the TS3+ dock altogether and had to find an apple brick and cable and used only 1 4k screen:

I had to use my phone because the keyboard is connected to the dock and I lost my USB A to C adapter.

The fans nor the usage went up at all based up whether I had external screens connected - 1 or 2 - or if they were connected without the dock.

I have no 3rd party utilities installed other than the caldigit utility for the dock. I've only been using the Apple activity monitor. I did run etracheck but it's not on all the time. Etrecheck can sometimes find problems with the software.

Sorry for the messy desk in the pictures.

Yes. I was using it in clamshell mode as at work, that's the best for me.

I've been running now for about 15 minutes with the lid open and the fan does run slightly. Here is activity monitor:

I really have to listen to hear the fans though in regular work. If I'm moving around big videos or big pictures, then they kick up but after I'm done they go back down. This is with all 3 displays going (built in, 2 - 4k). i don't know where to check voltages without buying an app.

Here is what it is if I am running 1 external 4k connected directly to the TB3 port with the lid open:

I left it run for about 15 minutes and it seemed to make no difference. Fans were nearly silent if not completely. Here is what I am running 10.15.3 with the build - to make sure we are running the same thing:

@gmn I will try and see if I can install iStatMenu. I don't want to install setupapp too.

This first one is 2 4k in clamshell mode:

Lid open with 1 4k directly attached:

One observation this time: I could hear the fans were running low with the lid open but are nearly silent with clamshell.

I'm not sure why my previous post on WindowServer was deleted, but it really seems relevant. As can be seen in the attachment the WindowServer process has taken 174000+ hours of GPU time within 1 day. This really seems very excessive, main tasks are web and sublime text. Temps are hot using external monitor.

I'm also having this annoying fan noise, minutes after connecting an external tv.

Even without using the computer, keeping it completely IDLE, the fans are at ~4500 rpm!

In Activity Monitor I see this:

I am connected to my tv for about 4 hours now.

PLEASE FIX THAT APPLE, THANK YOU.

Here is a screenshot after my mac was on for less than 24 hours:

The WindowServer process is showing 174,838 hours for GPU Time, now in my eyes that seems to be quite a high amount of GPU hours for not even running any GPU intensive processes, no?

As you can check on these 2 screenshots, I've using Apple devices for more than 15 years and I own a lot (a lot) of Apple products so I'm not new, and I had to deal with issues before, one time when the thunderbolt display was released I was the first person to use 2 of them connected to a 27-inch iMac and there was a flickering problem, it took almost a year for Apple to acknowledge the problem and fix it but it was because I was doing everything in my power to get that noticed. I love Apple products and I will continue buying them but if there is a problem I have a right as a costumer to use all the available channels to get it noticed.

Quote people from MacRumors post these stats might help

There is a pretty big difference in close lid and open lid as the power consumption on the new NAVI 5000 series GPU, which contribute to the heat displacement on the same heat pipe connect to the CPU.

Interestingly NAVI GPU supposed to be producing less heat in 7nm making, which reflected on close lid power consumption compare to 560x. But open lid is very bad.
