Not possible because the USB-C ports are only connected to the dGPU, not the iGPU.

I have one of these machines right now. 2.5GHz quad, iGPU only, 256SSD, 16GB Ram. It is not slow by any means. Geekbench 5 goes to almost 900 single and 3500 multi. My 2018 6-core got 1050 single and 4250 multi. How is this slow?
Intel Iris 5200 with two monitors 2560x1440 and 1920x1080 CPU stays cool around 50-52ºC. Try to do that with dGPU machines... My 2018 15 i7 goes up to 65 on this setup and since there is two chips drawing power the laptop gets hotter with the same CPU temps.
I still believe that if we users demand this, Apple will listen. As for me never again dGPU laptop. If Apple wants to launch iGPU 16 in mid 2020 I am considering it, otherwise sticking with my 2015 for the foreseeable future.
As a result I have a 2018 machine to sell, but my 2015 is a keeper.
My 2c: with availability of eGPU (which we didn't have in 2015) Apple done it, why not now?
Hi, it seems so in my case. I am now satisfied with the machine. GPU is not so important for me. I was more interested in getting 8 cores instead of 6 but not for the price of excessive fan noise.
I could still return the machine and try a Core i9 with the 5300M but I would have to wait two weeks until it is delivered. Maybe someone else can test this scenario? I did not read from anyone with such a machine yet. Only from people with i7/5300M or i9/5500M.

The other problem is that Apple basically “releases whatever” and the stock price and company valuation only goes ”up”...
But of course, none of that has anything to do with Macs whatsoever, so I guess we should all be happy they even make Macs anymore.
From a valuation standpoint, the company could release tools and Xcode for Windows and shut down all things Mac and they honestly might be just fine (it’s all iPhone, wearables and services at this point basically)
I actually believe there was a part of Tim Cook that was hoping the iPad would take over for most general MacBook users and they’d slowly just become the iOS & Wearables company and ”the Mac” would be the past.
Still might happen eventually actually
This dude on the previous page says that since it works fine in safe mode, it MIGHT BE a software/driver issue:

safe mode is a kind of “minimal Computing power” mode, loading only the essential. The machine gets laggy on this mode, hence it could use less power anyway.
but in all fairness I really hope it’s a software/ driver issue.
Well you could if you used a USB video adapter that uses displaylink
I can confirm - updating to 10.15.3 - no change - same 18-20watt usage from the Radeon.
Dammit there goes my home... Either way I'm playing games in clamshell mode with bluetooth mouse & keyboard, seems to fix my problems for now especially when I'm working from home.
Hello. I've been tracking this topic from december when i bought MBP16. I had same issues. When i connected external monitor 1080p fans speed up to 2500 rpm which was noticeble and then i try clamshell mode and issue has gone. Then i bought new Dell 4K monitor and fans went crazy, clamshell or not. Then i put the resolution to 1080p and fans went to normal. Then i start to google about usb-c multi hubs with HDMI and i find out that the most of them support 4K30hz only, so i bought new adapter which is only Usb-c to HDMI UGREEN not multi and supports 4K60Hz. Now all the heating, fan noise issue has gone.... Oh im so glad... I hope that will bi helpfull for you too. Sorry for my bad english. Regards.
Interesting! This supports what I experienced as well - I had to manually change resolution from 30 to 60hz, and that caused the wattage to drop from 20w to 5w.
It makes NO sense that half the refresh rate causes four times the wattage necessary.. major bug.
That about sums up Apple software quality these days - sadly
MacBook Pro 16 Has a Fan Problem
At the end of 2019, I traded in my two-year-old 15-inch MacBook Pro, sold off some older Apple gear (an iPad and older iPhones), and decided to spring for one of the newer 16-inch laptops. I had us…

I haven't read all 21 pages of this thread but I'd like to add my experience.
All Thunderbolt Macs I've used with external monitors immediately increased the CPU temperature by at least 10ºC. This never happened with the DVI Macs I used before TB was introduced.
- 2011 15'' MBP with TB1 and DG
- 2014 13'' MBP with TB2 and IG
- 2015 15'' MBP with TB2 and IG
- 2017 5K iMac with TB3 and DG
The heat was so bad on the 15'' 2015 that I ended up selling it and buying the iMac 5K.
I've always thought this was caused by the TB controller an not the GPU. In fact even connecting an SSD to the TB3 port of the iMac caused the increase in temperature. I've been using iStat Menus for years and I always monitor the temperature of my machines in either Mac or Windows.

I haven't had problems with my 2014 15 MBP, 2015 MBP 13 or 2015 MBP 15 and heat when connected to QHD and 4K monitors.
Do you think that those
who have returned the 16" for overhearing
can buy another one and test all the cable and 30/60hz variations?
My workplace provides a Mac or Lenovo (Linux or Windows). I bring my own Macs into the office.
Some workplaces do allow you to use personal equipment for work.
I am using 2015 i7 2.5GHz Intel Iris 5200 with one qHD and a fullHD monitor in clamshell and get 50ºC CPU temperature. With 2018 15 6-core i7 and AMD PRO 560X with only the qHD I get 55-60. The dGPU shares heat pipe with CPU and although Intel GPU is off the all system heats up.
Everyone's experience is different because we use our machines differently. Its normal. As for me dGPU laptops no more, thanks. Even with 55ºC CPU without dGPU the case gets significantly cooler than the same CPU temperature with dGPU.
Concluding, dGPU laptops are great for performance, but lousy for thermals and noise. As I already stated in these forums, I am sincerely hopping that a 16 iGPU is in the pipeline on the near (1-2 years) future.
Does this really work? I've been using a 4k@60Hz adapter with an LG 32" display and power consumption at scaled resolutions is still around 18-20W. Fans are quiet for a bit, but playing videos on Youtube etc. trigger them over time.
Without using the external display, switching off TurboBoost and dGPU the laptop stays silent even during my audio sessions. But, I haven't figured out a way to avoid ramping up the fans or power consumption while using an external monitor.
