MacBook 16-inch Fan Noise

Using 2x 1440p + 1x 1080p, I get about 90+ logs a second.

Same results if I set the 3 displays to 1080p or 720p.

This is using clamshell.

Using the command with no external screens makes it still logs around 20 times a second on my base 16".

Is this really an error or just an info log?

I was wondering the same thing but I run the same command on my iMac and it does not do give those logs or at that speed. I submitted a report. It does seem strange.

Define performance.

Power draw may be higher but graphics performance may be faster too.

For what its worth the overheating issue occurs in boot camp so it’s unlikely a macOS specific issue.

It's not "overheating."

That’s very interesting, can you tell us what model the monitors are and what cable you’re using to connect to them?

William ,

How are you so sure ? Ahmedfromreservoirs

computer is not overheating without physically inspecting it? I think it’s a little irresponsible to make such a condemnation ?

just sayin’

Yeah with the latest update to MacOS windows is now running 'better' in that it is unchanged while MacOS is consuming all the power.

Did you get any feedback from Apple engineers on this surface is not detached, CoreDisplay is detached debug message?

I have not heard back yet. I may or may not. It's about 50% of the time where they asked for more information, tests, and screenshots.

Yesterday I was sitting with the laptop running facetime only and safari, my client asked why are the cars so loud ? where are you !

that where the fans :-(

I think he is referring to the new one that will be available in a few days with the GeForce RTX™ 2060.

Ah - these things are always a cat and mouse game for what is newer and faster.

Well what we do know is that the easiest solution is not to connect an external monitor or possibly use it in clamshell mode, things that should be easy to do at home and normal for field use.

Common editing in FCP makes fans come to 3000+ RPM very soon
