New Macbook Pro 16 inch Overheating

I had the same issue. It started overheating when I was migrating my data from older Macbook to the new 16 inch Pro. I attempted to reinstall macOS Catalina the issue continued. Then I decided to delete all data from both HD Drive and HD Drive Data in recovery mode. I reinstalled macOS Catalina. Since then my Macbook Pro 16 inch has been woking like a charm. 2 days of full use did not hear the fans turn on. My guess the issue might be in migration assistant app.

Hope this helps.

Serg,

I had the same issue until I reset my System Management Controller.

Before I did this, my processor was operating around 60 Degrees C. After, I'm down to 33-35 Degrees C and battery is operating more as expected.

I hope this helps!

Had the same issue today with a brand new Macbook 16", found out that there was an issue with Nortons AV which I installed, it was running a process that was continous and overheating laptop, once removed machine went down to normal state and fan did not constantly run, now in the process of looking for a new AV that wont cause the same issue

Readers here are eager to help you with your MacBook Pro 16-in overheating. Some of the best advice is to install Turbo Boost Switcher and turn off CPU Turbo Boost. This reduces the huge sudden overheating brought on by Turbo Boost, that simply does not translate into real-world performance gains.

This computer was built with a ninth generation 14nm processor. The only way to meet the target performance was to make it a six or eight core processor. This processor generates an enormous burst of heat when it does Turbo Boost, and there is only one cooling rail shared by both the CPU and GPU. So getting Either side too hot ramps up the fans.

This processor was supposed to be an eleventh-generation 7nm processor, but intel is three years late, and is only starting to ship its tenth generation 10nm processors now.

Install Turbo Boost Switcher to allow the selective turning OFF of Turbo Boost, which is the main source of heat-spiking like you are seeing. The decrease in performance for most tasks is not noticeable.

Thank you for sharing the information about the activity monitor. I had no clue that software could cause the temperature to rise. Checking out the activity monitor showed me that excel was consuming lots of energy and I have not clue why but when I closed it, the problem was solved.

I was having the same issue with Macbook Pro 16 over heating , i was on numerous calls with Support nothing helped . They removed almost all of the 3rd party apps Except Microsoft Apps . But my issue still the same .

Then looked into Activity monitor i see One Drive is consuming a lot of CPU %. I went ahead and force quite the One Drive process . at the point my Macbook temperature came down to 47 Centigrade degree from 95 degree Centigrade.

I see this issue is can happen in multiple way's . i hope this hepls.

When you say browsing, what tabs you have open? Facebook with video autoplay? YouTube? You can switch in Activity Monitor to Energy tab and see what app is consuming energy.

Do you use external monitor? External monitor uses discrete GPU which produces more heat...

These laptops have powerful CPUs and GPUs. These computers should be way larger to provide proper cooling. Look at other mobile workstations from HP, Dell, Lenovo and see what sizes are these. You want thin, you suffer the fan noise...

I had the same problem, and found a solution for my new Macbook 16 (I have the default configuration).

I went to activity monitor and saw that a process called 'InternetSharing' was consuming the highest amount of CPU and had the longest amount of CPU hours.

I went to system preferences/sharing and unclicked 'Internet Sharing' from the list, and saw in Activity Monitor that the process was no longer consuming cpu cycles.

It immediately began to cool down - 3 minutes later and it's at room temperature!

Hope this helps.

You need to look into your WindowServer executable and see what messages are related to this in your Console App. Try sorting by "error and faults" for both window server and all processes. This may give you a hint. The fact that your GPU is also using significant resources points to an issue with the display. Are you using an external monitor especially one on a 4k display?

Those single-threaded activities could have their heat reduced by Turing OFF Turbo Boost, such as with Turbo Boost Switcher. The difference in performance is not likely to be noticeable.

Chrome... its using 30% of your CPU.. not a hardware issue. Chrome will almost always demand turbo-boost due to the VP9 video codec, which enables 4k playback on sites such as YouTube, which Apple does not natively support. In any event, the temps are not an issue, but the fans are. When the first core turbos the fans were programed to preemptively spool to avoid the thermal throttling and heat soaking the latest 15" models were experiencing. I believe they provided an update which changed these profiles back to something more reasonable. Also, i know the fans (and overall temps) operate a bit higher when plugged into an external display. I hope you can finally enjoy your purchase. I know I love mine...

@tripletabs, your university should find different job for your technical consultant... It is OK to keep your laptop connected to power.

Actually your computer will perform better with power connected because it doesn't need to preserve energy.

50-60deg C is normal temperature at idle. If you have all apps closed, it may still spike the temperature when it is downloading updates, or indexing files etc.

I used app to manually control fans and set them to full speed. With maximum cooling I wasn't able to bring temperature down below 47deg at idle.

Overheating means the computer is freezing and shutting down by itself. If the vents are obstructed and air cannot flow, the fans will speedup and the CPU will throttle itself down in order to protect itself from overheating.

I bought Macbook Pro 16 inch December 2019, only after the seventh time of using it, while I was watching a youtube video, having nothing else opened the laptop started to overhead, then it kept shutting down the whole system.

I took it to apple center, after a week, they called saying they could not figure out the exact source of the issue, and advised me to return it back and re-purchase another new one. which I did, and I thought that might be just unlucky piece of Macbook Pro.

I got my new Macbook Pro 16, yesterday it is the second time using it, just installing my programs where it started to overheat and the fan sound was very load.

I had put almost $4000 for this piece with Ram 32GB, 1T storage, and the latest core-i9 processor! I had an older version of Macbook pro, with away less qualification at work, that works almost without any overheating issue while I have all my programs open even over a several days.

I think this is a manufacture problem with this Macbook Pro 16 inch.

I'll return it back, and re-purchase an older stable version of Macbook pro.

I hope that apple would realize and admit this issue with the 16 inch mac soon and take all the pieces of Macbook Pro 16 inch off the market and save their customers time and headache for having alarming problem with such an expensive investment.
