Many owners MacBook Pro 2016 si MacBook Pro 2017, 15-inch models with Touch Bar, complains that laptops heat up very hard on the top of the Touch Bar, when running a video content, an application that requires hardware resources is open: Adobe Photoshop, Affinity Photo, Affinity Designer, Final Cut Pro X or programs for editing and creating audio content.
A pretty serious problem, especially if we take into account these models MBP (MacBook Pro) are bought mainly for graphics production, audio or video lesson. About pricing we all know that they are not at everyone's fingertips, talking about devices that go from 1200 dollars.
Before we panic about this surface heating at the bottom of the keyboard or the top of the Touch Bar, we say that it is not a problem if these parts heat up within reasonable limits. When CPU or hard drive is required intensely in operations, there may be situations in which CPU temperature to get to 75° - 85° C, which leads to heating the front surface and back a MacBook Pro.
MBP cases are made of aluminum, which means we have to deal with a very good heat conductor. When a hardware component heats up, the aluminum case will almost instantly take the heat and take it to the outside, where we canesimyou by simple touch with your hand.
However, if the temperature grows unreasonably, we need to keep in mind if they are respected the optimal operating rules of a MacBook Pro.
Factors that can lead to overheating MacBook Pro
1. First of all make sure that we are running the latest version of macOS / OS X for our MacBook model. We do this from App Store → Updates.
There may be bugsof both the operating system and the applications, which can lead to excessive heating. Most of the time they are solved in a short time Apple or developers.
We install any updates of the operating system macOS and applications.
2. Placing the MacBook on a leather or textile surface (blanket, carpet, sofa, etc. fabric) can impede the circulation of air in the room around it, and this leads to overheating. It is recommended to be used on the desk, on special tables or on flat and hard surfaces, which allow air circulation.
Standing "feet" are also an accessory help cool down and ventilate proper. I have written about them in This article and I made a recommendation.
3. Protective cases for MacBook they may also be a cause of overheating.
These accessories provide protection against scratches and shocks that may occur at the cabinet level, but even with ventilation slots, the hard plastic or soft silicone made of them do not provide an as good heat exchange as do what its aluminum case.
4. Ambient temperature. It is known that both MacBooks and other types of laptops or PCs suffered in the summer due to high temperatures in the office, at home or in the environment in which they operate. The fan coolers become noisier and the front and back surfaces heat up more than in other seasons.
Optimal abient temperature for the operation of a MacBook Pro is between 10 ° and 35 ° C, with a moisture between 0% and 90% without condensation.
5. Another cause of heating, this time especially a Battery / Battery or sourceThis improper connection of the power plug in the adapter or in the input MacBook. Make sure you use both power supply and power cord original or with certify Apple.
Do not use improper cables, damaged plugs or unstable sockets. Besides overheating your laptop, there is a risk of fire or electric shock.
These would be the main factors that can lead to overheating of a MacBook, but there can be other causes as well. Viruses / malware, adware applications or other types of programs in this category can overload the hardware resources of the laptop.
If none of these causes the overheating factor, fan fans (fan speed) do not work in optimal parameters, a reset is recommended SMC (System Management Controller). Among other sensors, the SMC is also responsible for "thermal management".
