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.
