MacBook Pro 16 gets very hot

Hello, I bought this device for one day. MacBook Pro 16 and in less than 2 minutes after turning on when working with Safari and I'm just checking the site, there is a lot of heat at the top of the keyboard above the touchpad and behind the device. What should be done about 43 degrees Celsius? Is this normal?

Yes, seems normal the late 2019 MBP 16" with the limited information you provide.


If this is brand new, I would use it for awhile to further test as you set it up, and things settle in....


Background updates can happen with no notice to the user when online, Spotlight re-indexing the new environment, etc on a "one day old " new Mac . This can run the temp up seemingly for 'unknown' reasons. I would not be concerned here.


The Dedicated gfx card will always run warmer then the Integrated graphics card.


I will add you have 14 days for a full refund or exchange for one that suits you better—if that is your resolve.

If you are using an external monitor, one insight is to have the charging on the right hand port, external monitor directly in left side ports.




Keep your Mac notebook within acceptable operating temperatures

Your Mac can run at 60 degrees C all day every day without any bad effects whatsoever.


that computer is the "Muscle-Car" of notebook computers. Since it is far more capable, you may be lulled into installing anti-Virus file scanners, optimizers, speeder uppers, or third-party File-syncers you used previously. Because it is so fast, it barely waits for the drive to finish. It can do busywork really fast, which will cause it to heat up in a previously unseen way.


This computer was built with a ninth generation 14nm Intel 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.


Apple DID redesign the cooling system for this specific Mac. New, high-efficiency fans are used. But for some uses, that is still not enough.


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.

If you bought DIRECT from Apple, and NOT from a Reseller, you have 14 days to return the unit for full value. If you hate it, do not delay -- the 14 days is firm.

Your MacBook Pro measures internal temperatures and adjusts its fan speeds downward several times a second. The fans work to remove the excess heat. If that system fails, the fans automatically revert to maximum as a fail safe.


Your Mac can run all day ever day at 60 degrees C with no bad effects. If the internal temperatures ever exceeds 100 degrees C, the processor circuitry will cause an automatic emergency power-down to save itself from heat damage. This model MacBook Pro is a BIG step up in capability from a Microsoft Surface.


Do not run third party virus scanners of speeder uppers on this model Mac. They provide no benefit, and WILL cause overheating, because they are calibrated to less-capable models.
