One of the benefits of multi-core processors is that you can put more computing power into your computer without requiring absurd energy consumption, as well as not damaging it with high temperatures. The problem that, in the case of Apple, equipping a MacBook Pro with one of Intel's latest generation Core i7 chips does not appear to have been a very beneficial decision in this latter respect, considering that its heat dissipation techniques left something to be desired in a test done by an Australian website.
During abenchmark realized with the Cinebench, a MacBook Pro Core i7 registered temperatures of up to 100C in its processor, capable of making the water boil at sea level, while a Fujitsu model equipped with the same chip reached a maximum of “only” 80C. It is believed that there is something wrong with the internal cooling system used by Apple, but its aluminum housing also retains heat with enormous ease, so this is a characteristic that also deposes against.
The test results do not appear to be influenced by the machine's operating system or anything like that, but the fact that a MacBook Pro can become quite difficult to use in circumstances like this. Even if the overall internal temperature does not reach 100 ° C, the heat from the processor is conducive to being conducted in a short time throughout the external area of the laptop.
Looking calmly at the analysis made by MacDailyNews about the article cited in this post, it is clear that some points on it are not really very clear, especially regarding the heat conduction of the processor (the only component that really reaches 100C) to the rest of the machine. Depending on the case, this heat may not influence the use of the laptop as much as the original article tried to imply.
In addition, it is worth remembering that the thermal limit established by Intel to the Core i7 of 105C, therefore the temperature recorded by these tests remains within acceptable operating standards. Finally, it must be clear that the machine has been subjected to a benchmark heavy, whose circumstances may not reflect the common situation of MacBook Pro users.
