(2019) 16" is HOT & NOISY with an external monitor! :(

supaninjax said:
So is it confirmed that the 5600m doesn’t experience these issues? I’m tempted to sell my 2019 16’ and get the 2020 version with 5600m because my current machine is unusable in it’s current state. But being as it’s July I know a refresh is coming soon. Not sure if I should buy the 5600m machine or wait for newer models.

By the time Intel comes out with a meaningful true 10nm replacement for 45 watt notebook class chips that the MBP 16 is using, we will be fully into ARMac product releases. (The latest 10th gen chip for 45 watt class is a fake) The 5600M is also state of the art for 50 watt GPU class so I don't think there's going to be any meaningful refreshes until the MBP 16 is replaced with ARM.

Please help! My situation MBP 16 connected to one (1) Apple Thunderbolt Display via Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter https://www.apple.com/shop/product/MMEL2AM/A/thunderbolt-3-usb-c-to-thunderbolt-2-adapter Its a only way to connect, so i cant use any other cables, as i understand (i am wrong?). Working in calmshell mode, lid closed. Its SO hot and noisy even in idle state! Radeon High Side ALWAYS ~18W. I READ through ALL this thread! 94 pages - i tired SwithResX - no avail. I read a lot of post that Radeon High Side must be ~4-5W in clamshell mode. But not for me :( PLEASE HELP. I need bring temp and fans down to work. What can i do? Any workarounds for Apple Thunderbolt Display??? HELP HELP PLEASE!!!

Welcome to the club
We're about 8 months in waiting for a fix
I've resigned to the fact that my MBP 16 is really only usable in lcd or clamshell mode unless I want high heat and throttling.

The Thunderbolt display might be a special case as you also have a thunderbolt hub in there that may be triggering the higher GPU usage.

Return it if you can and pay the extra $800 for a working laptop or just wait for ARM Macs as that's where Apple is focusing all their energy into this moment.

i am not using any sort of hubs, only Apple Adapter. I read a lot of posts that in clamshell you dont have hot and noise and Radeon on low Wattage. But its not my case :( What i am doing wrong??

You have a hub in there. Look at the ports on your thunderbolt display:

Peripheral connections


That requires a thunderbolt hub of some sort.

Get a USB C adapter to HDMI and plug in your TV. When in that mode, my GPU consumes only 6-7 watts.
 
Any way to disable hub? and maybe i can connect to Thunderbolt port directly? Is there any USB-С to Thunderbolt 2 cables?
 
So am I to understand that when you use anything more than a 1080p display this overheating and noise occurs? I've hooked mine up to several 1080p monitors with no problem (one at a time, however).

No... I’m using 2 x 4K displays and MB Pro in clamshell - but one monitor is upside down. If standard rotation the power usage jumps (see my earlier posts for more of an explanation). Smells like an opportunity to mess around with SwitchResX but not something I have time for at the moment.

Apple always updates their MBPs around Sept-Nov every year

That’s simply not true. Even in clamshell mode I get Radeon high side 18w+ when connected to my XDR 6k display. I only use my laptop in clamshell mode when using an external display and have always had this problem. Not sure why some users report that clamshell mode fixes it, it doesn‘t

That may be true but Apple will still release a newer late 2020 16” MBP this year around Sept-Nov like they do every year. It may have the 5600m gpu or a newer one and it will also have some other updates as well. Which is why I‘m not sure if I should buy the current 5600m MBP or wait a few months for an updated MBP

ARM 16“ MBP’s won’t be till late 2021 and I’m going to hold off on those for a while since they won’t be compatible with most current apps and plugins

**** :( Anyone here with Apple Thunderbolt Display?

And BTW - someone checked 10.15.6 update? New beta was posted today. Maybe some improvements?

Everyone's mileage varies depending on their own monitor setup. Some are getting low power with a single or dual monitors. In the case of the XDR suspect it's like having two monitors off the same bus. If I have both 4K monitors on the same bus I'm getting 21W Radeon High side. On separate buses with one rotated 180 degrees I get 8W.

That makes sense but there are many others here that are experiencing the same issues with different monitors in clamshell mode as well. It definitely depends on the monitors / cables though. Some users aren’t experiencing anything even with the MBP open. I suspect resolution of the monitor has a lot to do with it

May anyone check if one 1080p (or 1680) display with lid open works fine without dGPU high wattage? I ask because this all wattage stuff is the only thing holding me from buying basic 5300m/6core MBP16.

So far nobody showed a working setup (dual 4K monitors and and open lid) with 8W or less by my knowledge.
It looks more like a generic issue.

I was talking about clamshell mode. I agree with the fact that if you have the Macbook Pro open and another monitor it looks like GPU power usage is well above 8W.

Edit: For fun I tried my 1920x1200 monitor on its own (connected via DisplayPort). In both clamshell and MBPro open I was running at 19W. Back to my 2 x 4K monitors in clamshell (one rotated 180 degrees) and I'm around 9W. Not sure why it is 1W higher than before.

This is unpredictable.

Edit: Killed some Safari tabs.. that was the 1W extra

Ugh... I just wanted to thank everyone for their work on this issue. My 16” 8-core is still in transit to me, but I’ve decided I’m not even going to open it. Straight back to Apple.

I’ll stick with the 6-core Cylinder and 2012 rMBP combo for now, then see what ARM brings later in the year.

What a shame - it’s otherwise such a great laptop.

Open it first so they take a small financial hit on the return. Might motivate them to fix it. Plus, you might as well see for yourself how it works.
