FWIW I run the same machine (except 32 GB) and a 4k external display. It's silent when idle (~45C) and quiet even when loaded (~97C).
Yikes, that seems like an issue on its own. It's generally not good for parts to get that hot regularly.
If your laptop CPU is at 100C and the fans are quiet, you're wasting a lot of performance potential.
Heat cycling the motherboards will definitely shorten their effective lifetime significantly. There's no reason not to have proper cooling.
Having said that, modern Thinkpads are not great in this regard either.
Servers in our HPC cluster runs with similar temperatures even with enough cooling and we change CPUs very very rarely.
**** SMC sensors ****

Excuse me, but that's exactly the case here.
Only Apple can brag about "learning about mistakes" and then have temerity to do them even worse.
The MBP has poorer thermal solution than noname Chinese OEMs that market similar machines at $700-800. Just look at that wimpy single heat pipe and the radiator sizes.
I'm hoping that 10.15.3 which I installed yesterday will help remedy.
Weirdly enough this only happens if I don’t turn off the mac for days (only putting in sleep mode) and when the ram is close to 16GB.
However, when the ram gets to 16GB, the only thing that gets impacted is the video, there is no spinning wheel, audio doesn’t stop. Just the video stutters for a bit, then jumps to present.
The theory here is that the onboard graphics card doesn’t have enough ram for it, it is being swapped constantly, which causes the stutters.
I hope a system update will be enough to fix it.
Edit: adding “no” to spinning wheel
If not, it sounds like a defective unit. I'd strongly recommend taking it to Apple Store.
I had no issues with laggy keyboard input, freezes and battery life was very solid for me. I've returned the laptop not because of these issues but because useless touch bar and large trackpad on top of Catalina issues.
There could also be an issue with your SSD or HDD. To come to a conclusion try putting your SSD to another MB and see wheres the issue
The SSD is soldered directly to the logic board, so that may not be a viable strategy.
If this is due to the processor being overstressed, Malik's fan issue may be related.
I think you should bring your computer in for service. I haven't had a fan problem when I have used the computer.
You can also try disabling turbo boost. See http://www.rugarciap.com/turbo-boost-switcher-for-os-x/
A very different problem that’s almost never discussed is the fact that you cannot always plug two different displays via TB3 in, one on the left and one on the right, without triggering some bug that doesn’t correctly enable the respective other display until the cable is removed and 20 or more seconds waited until it’s plugged in again. That’s been the case for the 2016 and my current 2019 model, and it’s been the case for everyone in my team with two or more displays via TB3.
Right now I own a high end LG TV from a couple of years ago and it won’t wake reliably when I turn on the Apple TV device attached to it. Sometimes, but not always, it requires both the TV remote and the separate speaker bar remote in addition to the Apple TV remote. Occasionally, to get a picture I even resort to restarting the Apple TV by unplugging it.
In my office, my monitor on both my new Mac Mini and on my Linux box both flash up a screen for about 2 seconds then turn off and the a second later turn back on. This happens every time they wake from sleep.
It just seems strange that with all the technology inside these devices that the first impression they make looks like some senior design electronics project powering up.
The author could have also maybe taken a look at what’s actually causing his problems with a simple click on the standard-issue system monitor. Not doing so is either disrespecting his readers, or just gross incompetence of the kind that doesn’t go well with his long-winded claims of being "professional“.
My last three macs have had the same experience.
Personally, I just don't want a laptop that big -- I've always preferred the 13" models to the 15". So I'm waiting to see what happens with both the 13" MBP and the Air.
I'm still holding out on my 2015 MBP as well, hoping to get the new 13" with the good keyboard.
Otherwise... surface book it is...
I did see the comment from someone saying it'll be upgraded to a 14" the way the 15" became a 16"; while that's a reasonable guess, I don't think there are any supply chain rumors supporting that yet, and the 16" update had rumors nearly a year in advance of its release. My personal expectation is that we'll see an upgrade to the new keyboard in the 13" before WWDC, but it'll stay 13".
Not entirely sure if I will buy another Mac again. Cant believe in less than 10 years since Steve passed away I am thinking of going back to Windows.
The higher key travel and further spacing apart from each individual key means I can actually differentiate between keys by feel, unlike with the older butterfly keys that all kind of blend together. The travel makes a huge difference in feel as well, as they're much less clicky.
If you're ever near a store carrying the newer model and an older butterfly model I suggest you try it out yourself.
I've experienced more issues with what I'm guessing is Catalina or driver-related bugs. Once when disconnecting my monitors I got RGB "static" on the MBP screen, had to force power down. Another time the touch bar quit working due (I think) to an external monitor plugged in. A restart solved that.
The author of the blog should seek technical assistance for his hardware.
The one thing that does bother me: I have a hardware USB switch that Catalina doesn’t recognize properly (works fine on Mojave).
With load, of course the activity monitor is the friend. Far too often, web pages manage to put load on the machine, even if they appear to be idle. In firefox, use the task manager to find the biggest offenders. Sometimes just reloading them reduces the load.
One big influence factor unfortunately not shown in the activity monitor is the GPU load. Just plugging an external 4k screen into my MBP causes the fans to spin up. This is also a good reason for web pages to create fan noise
I made a conscious choice to avoid the top of the line i9 and chose the i7 instead for the last of the 15 inch Pros (mid 2019) looking at the thermal rating on Intels website (45w vs 60-something if I remember correctly)
The 16 inch ones are simply ridiculous with this. Even at home in the US, I have a desk fan pointing at the machine alone so it doesn’t heat up too bad.
I currently have 15 windows, 10 chrome windows, around 200 tabs, 20 sublime text boxes, and a ton of other apps open(and plugged into an external monitor besides the Laptop screen itself)
Keep in mind I have a 8gb, 2.0 ghz laptop and is running all this. Sometimes I do get a kernel panic (forcing me to shutdown) but otherwise, I have absolutely no problems. It’s so surprising how my machine is able to handle all this.
My personal 2015 model does not (yet) have this problem.
Author doesn’t reveal how many TB of SSD he configured, but maybe powering 64GB of not-LPDDR and lots of TB of SSD is what sets the fans off.
Help, I'm using CPU intensive apps on my laptop and the fan is coming on! Okay, and the sky is still blue?
I'm sorry but I just can't stand this post. One thing that may help the author that I don't see mentioned here is plugging it in. Seems running off AC power is less thermally intensive than battery.
I favorited because I am interested in discussion of potential issues with the 16”; I didn’t even read the article.
If you had read it properly he said one time he had just booted it and had 3 Apple apps running (Mail, iMessage, and something else) and the fans were still loud. He says he'd understand if he had Photoshop open with many layers...
Good performance and good thermals: it’s going to be a thick laptop (or a desktop) with good airflow, portability will suffer.
Good thermals and good portability: you’ll end up with something like an IPad Pro or a surface. performance will be lackluster.
Good performance and good portability: The thermal solution will be sub par because it’s designed too thin, light, etc. This is basically what we have here with these specced out 16 MacBooks.
Given the number of complaints, I'd wager the first or second.
AIs will just make make their own photos. The cloud does not need you.
Maybe a lower specced model would do better...

I've been through so many laptops. After I tried a desktop in 2019, I can't seriously consider a laptop, unless in a pinch. Even so-called "beefy" workstations, e.g. W series Thinkpads, I've returned. They throttle too.
You want to know what beats a $3500 Macbook Pro? For me, a desktop with "ok" parts and water cooling.
You'll never have a fan issue. You get to use high quality parts that are replaceable with their own warranty.
Even the cables are super high grade. And you still come in at a third of the cost, slightly more than half the cost if you want to splurge.
You'll never have slowdowns. You can power multiple 4k monitors, ultrawides, whatever you want.
It boils down to keeping all these parts in a small chassis. If Apple cared, they'd stop the soldering and add an inch and half thickness and let the thing ventilate, because these things are built for consumption, not creation (e.g. being under an intensive rendering/compilation/io workload).
Watercoolers do have fans, so not only can you run into potential "fan issues" but you can also have a "pump issue" on top of that.
That being said, I am keen on creating an SFF build in the future.
