Apple announced the new 2021 MacBook Pro models recently and the new laptops have a lot going for them. While the new design is a more than welcome addition, the new M1 Pro and M1 Max chips have clearly stolen the show. The new Apple Silicon is not only powerful when it comes to performance but also power efficient. The new 14-inch and 16-inch MacBook Pro models feature a new chassis with improved thermals that Apple says that you will rarely use due to the efficiency of the M1 Pro and M1 Max chips.

According to Apple, the new thermal system in its 2021 MacBook Pro models have the potential of moving 50 percent more air at lower fan speeds. Since the new M1 Pro and M1 Max chips in the MacBook Pro models are greatly improved, one would presume that the fans would make a lot of noise. This is due to the fact that performance comes with a caution - thermal issues.
