MacBook Air gets hot. Solving the listed problems Mac Pro
WITH passive cooling- they emit heat during operation, and there is no escape from this. This is quite normal as long as the temperature is within acceptable limits. But, if you hear the noise of the cooler running at full speed, and your hands begin to burn on the heated case, it’s time to do something.
Laptops are primarily susceptible to overheating (due to their portability), but monoblocks and desktop computers he is no stranger either. So our advice will be useful to all poppy growers without exception.
Why does my Mac overheat?
Before we start dealing with overheating, we need to understand its essence. The reasons for increased heating may be different, but in the case of Apple computers Usually it's a matter of too tight placement internal components due to the compactness and lightness of the devices. Despite energy efficiency increasing every year, when large number components are located in a small housing, heat generation inevitably increases. If you don't pay attention to elevated temperature, then over time this will affect the battery life, and can also lead to damage to other components, such as the video chip.
How to avoid overheating
Check resource-intensive applications
Applications that hog your Mac's resources are one of the biggest causes of overheating. Sometimes applications freeze or crash, using the processor to its maximum and, as a result, causing increased heat generation. You can find frozen and resource-intensive applications through “System Monitoring”: all processes that consume more than 70% of the processor power are classified as “gluttonous”. If this is not the main tool you work with at the moment, For example, Final Cut Pro, calculating the project, it is better to complete the process. And resources will be freed up, and the Mac will not heat up as much.
Control the temperature
Temperature monitoring is very important if this is not the first time you have noticed the roar of coolers and burned your knees with “hot” temperatures. aluminum body. You can be guided by these signs (cooler speed and case heating), but it’s better to use special tool monitoring.
One of the best profile utilities is iStat Menus 5. It provides the most detailed monitoring of all system parameters, including temperature from all installed sensors. Additionally, it can be used to regulate cooler speeds, as well as find out which applications are loading the processor.
Place your Mac on a hard surface
It would seem like a banal piece of advice, but many people still ignore it. Working in bed or with soft cushions on the sofa will almost certainly result in increased heat depending on the intensity of your work. This happens because the vents are blocked and the natural air circulation around the Mac's body, which is also a large additional heatsink that dissipates heat, is disrupted.
Therefore, if it is not possible to work at a desk, try to place the computer on a hard surface. In bed, you can use a special stand, a table, or just a large book placed on the pillow.
Avoid heat sources and poor ventilation
The previous advice concerned MacBook owners, and this one is addressed to iMac and Mac Pro. Some users don't care correct location their desktop computers, but in vain. For example, your iMac should not be pushed too close to a wall, as this will disrupt natural ventilation. Mac Pro should not be hidden under a table or in cramped niches of shelves. There is no need to place computers near radiators, fireplaces or any other heat source. Additionally, it is not recommended to use your Mac in areas with temperatures above 35°C.
Don't forget about prevention
No matter how clean your room or office is, there is still dust that collects in your Mac's cooling system. Therefore, it is very important to regularly clean dust - especially if you often work on the go - and replace thermal paste. If you don’t do this, dust will eventually clog the cracks of the thermal interface heatsink (or even the ventilation holes), and your Mac will turn into a noisy stove, which will not turn out well for either you or it.
Clean the dust on ventilation holes You can use a soft brush or vacuum cleaner, first reducing its speed to a minimum. About once a year, your Mac could benefit from cleaning by disassembling or at least removing the cover.

“Advice is good,” you say, “but everything is clear with them.” What should I do if my Mac gets hot while doing work? How to reduce heating and its consequences in case of regular loads?
Do not neglect regular heating even to 80–90 °C. This is not a critical temperature, but if it persists for several weeks or more, there is a possibility of negative consequences. I'll give an example from own experience. On my old one MacBook Pro I worked with text and photos, rarely loading it to its full capacity. In 3.5 years, I “specifically” loaded it only twice: during the passage Diablo III and when I was editing a backlog of family videos into FCP (both times in the evenings for several weeks). It would seem that this is not such a big load, but two years later it came back to haunt us with the failure of the video chip. On new MacBook Air I don’t do that anymore, but I do it differently.
Apple computers work with an emphasis on comfort of use, so the cooling system begins to work actively when reaching relatively high temperatures. Usually you can’t hear the coolers at all until 70–75 °C, and only then do they start to spin up. You can change this behavior of the system using an excellent free application Macs Fan Control.
We just need to select the desired fan (if you have more than one) and change its control method by clicking the “Sensor-based” button. Next, select the “Sensor-based” option and select the hottest component (for me it’s CPU Core, since the graphics are built-in). All that remains is to ask maximum temperature and the temperature at which the cooler speed begins to increase. For me it is 65 and 45 °C, respectively. The utility can be added to autorun when the system starts and forget about overheating problems altogether.
By following the tips above, you will surely reduce the temperature of your Mac, which in turn will allow you to not worry about overheating. As a rule, simple common sense and periodic monitoring are sufficient for this. If the described recommendations did not help you and your Mac continues to roar and heat up like a stove, do not delay and contact service center.
For many Apple users, their MacBook is a real work tool. And when a tool fails, it is at least unpleasant. In general, it suddenly turned out that the MacBook Pro 2017 was heating up, and to very noticeable temperatures.
Naturally, great concern was caused, firstly, by the very fact of this kind of trouble, and secondly, by the fact that this is a MacBook Pro 2017. It is clear that a MacBook (as well as any other laptop) should not behave like this, but If he did, then there is a clear symptom of a serious problem.
We started to figure it out and it turned out that this time everything was a little simpler than it could have been. Plus, along the way and with the active assistance of more qualified comrades (by the way, we recommend laptop repair in Kyiv on Podol) a small list of recommendations has been created that will help eliminate the overheating problem.
And that’s exactly what we’ll talk about now.
But first let's warn that some of the activities listed below require at least basic knowledge and experience in handling such a complex (and expensive) device, which is the new MacBook Pro (and not new one either). Therefore, if you do not have such knowledge and experience, then it is better (and cheaper) to immediately turn to specialists for help.
So, what to do if the MacBook Pro 2017 is heating up.
So, in order and without haste:
diagnosing the cooling system
At the initial stage, standard software tools are sufficient. Namely: " Functional test of Apple hardware " And Apple Diagnostics (to check the operation of the fans).
cleaning the laptop
This procedure is routine and must be carried out regularly, especially if the laptop is used very actively and/or frequently unfavorable conditions. To clean your MacBook, you must first unscrew the screws with a screwdriver and remove the bottom cover, and then carefully blow out any dust and dirt that has accumulated inside the case with a stream of compressed air.
Because, let's repeat ourselves, if you have never done anything like this before, then there is no need to take risks this time. Contact the SC.
close unnecessary programs
Unnecessary applications and sites, if there are many of them, as well as so-called “third-party” (i.e., not certified by Apple) programs (sometimes one is enough), can create an increased load on the system, which can ultimately lead to overheating of the laptop. Therefore, if you notice an increase in temperature, simply disable programs that you are not using at the moment and close unnecessary sites in your browser.
Let us also recall that macOS provides for monitoring the system state. special utility, it's called " System monitoring " (or Activity Monitor).
updating the operating system
Apple constantly optimizes the OS of its devices, simultaneously eliminating identified bugs and increasing the performance and security of the software, so update MacBook system Pro 2017 is also needed.
install your MacBook Pro correctly
You should not place any laptop on a soft surface that could block air circulation inside the laptop. The manufacturer recommends that the machine be placed on hard surfaces that do not interfere with the operation of the cooling system. And if there is a special stand, then that’s very good.
We are interested in the efficiency of the fan
Using a free program like SMC Fan Controller, you can control the current system temperature, as well as the rotation speed of the system fans cooling macbook Pro.
restart SMC
Easy SMC reset (aka System Management Controller, also known as the system management controller) often helps eliminate not only the problem of overheating and a whole series other problems with the MacBook Pro hardware.
To restart SMC do the following:
- turn off the MacBook Pro and connect it to the network using the power supply (the battery charging mode is automatically activated);
- press and hold on the keyboard for a few seconds Shift + Control + Option and at the same time press the power button;
- turn on the MacBook Pro (SMC parameters have been reset).
If all the measures listed above did not have the desired effect, that is, the MacBook Pro 2017 is still heating up, then:
1. Create backup copy all important data.
2. We take the MacBook Pro 2017 to a service center or call a technician to your home.
With passive cooling - they emit heat during operation, and there is no escape from this. This is quite normal as long as the temperature is within acceptable limits. But, if you hear the noise of the cooler running at full speed, and your hands begin to burn on the heated case, it’s time to do something.

We regulate the operation of coolers and solve the problem.
Windows heats up Apple computers much more than native OS X. Not for everyone and not always, but this happens often. Moreover, twice already the devices of my friends ended up in the service after working at Bootcamp.
Main reason- absence thorough adapting Windows to a specific Mac. The result is improper cooling of the processor and more.
I was convinced of this without additional utilities. My 15" MacBook Pro noticeably warms up when I start Windows. Even without resource-intensive software.
If you also encountered this, this material should help configure the operation of coolers and, as a result, cool the device.
It's better to protect yourself from overheating problems.
A visual comparison of the two systems
I spent several alive tests, having previously launched a utility for measuring processor temperature on both systems. I’ll say right away: these are the performance of my 15-inch MacBook Pro, mid-2014 model with an i7 2.2 GHz processor (i7 4770HQ). They may be different for you.
The test conditions were equal. Below are the average values, their error may be 1-2 degrees Celsius.
System startup, inactivity:
Surfing in the browser:
Watching 1080p video on YouTube:
Right now I’m writing an article in Safari on OS X (without switching tabs), the processor temperature is 32°. Windows can’t even dream of such numbers, even if the laptop is completely idle.
Perhaps some background issues are partly to blame system processes, which load the processor. I tried disabling services - it didn't help. As a result, my Microsoft system is 24° warmer in places than OS X.
So, let’s set up the operation of the coolers. Let MacBook is bigger noisy, but will last longer.
Cooling MacBook on Windows
Problem: MacBook's built-in coolers turn on either too late, or at high temperatures work not intense enough. We wish automatic system control from Windows all the best and take control into our own hands.
The free multi-platform utility Macs Fan Control will help us with this. You can download it from the official website, Russian localization is available. I found it quite simple, intuitive and convenient. But if you wish, you can choose any other one.
Right a list of temperature sensors is displayed.
Left– a list of coolers, their minimum, maximum and current speeds (revolutions per minute). My MacBook has two of them: left and right.
In the screenshot, the coolers were controlled by the system (Windows). The utility offers 2 new modes – manual control And binding to a specific sensor.
We select the second method – “Sensor based: CPU Proximity”. Sensor CPU Proximity- This general temperature processor, which means the rotation speed of the coolers will change depending on its readings.
Now the most important thing: we set the values so that the operation of the coolers is as close as possible to OS X. I conducted tests on both systems during the day and, it seems, made their operation similar.
I'll tell you in more detail.
So, we have two options available for editing:
First– processor temperature at which the cooler will begin to increase its speed. If the temperature is below this value, the cooler operates at the minimum possible power.
Second– processor temperature at which the cooler accelerates to the limit of its capabilities and cools at the maximum possible speed.
On my MacBook I set the values 49° And 76°. This means that up to 49 degrees my laptop does not increase the cooling intensity and runs very quietly. More than 49° – gradually increases the fan speed and, accordingly, the cooling speed and noise. When it reaches 76°, the coolers rotate at maximum speed.
If the laptop makes a lot of noise at these values, the maximum processor temperature can be increased, say, to 80 degrees. But this does not mean that it will not heat up above 80. This only means that once the processor reaches this temperature, the coolers will start working at full power.
Theoretically the majority modern processors Intel can be safely heated to 95 degrees, but this is the peak: it is better not to experiment. Especially on a MacBook. The maximum allowed temperature is 100 degrees. Next, the processor will most likely begin to skip cycles or turn off (the protection system will work). Well, or if you are unlucky, it will burn to hell.
I wouldn't let it get above 85-87 degrees.
What else can you do?
Disassemble the MacBook and clean the coolers.
How clogged they are with dust depends on how the laptop is used. But if this happens, then they have to work in enhanced mode to provide the computer with the necessary air flow. Hence - excess noise and poor cooling.
If the device is a year and a half or more old, then it’s probably time to clean it.
Pictured is a 2012 MacBook Pro.
It's better to take it to a service center. And ask that they do it carefully and in front of you.
Precautions
You should not play with the cooler control utility - if you set low values, you can overheat the processor. You need to set it up carefully and constantly monitor the processor temperature in the first few hours. Try to run resource-intensive programs, monitor sensor readings.
If there is personal experience for setup - welcome in the comments.
In this article we will talk about why the MacBook Air gets hot or the MacBook Pro makes noise and gets hot.
To prevent your MacBook Pro from heating up, it needs to have good air circulation, this can be done simple method- just install the laptop on four matchboxes.
If your warranty card has not yet expired, you can take your MacBook to a service center, they will clean it for you from all dust.
Eat alternative option To solve this problem, buy a mat with a cooler and your MacBook Pro or Air will never get warm or hot again. This the method will work for those whose macbookpro is or has been heating up too much.
It is advisable to clean your computer every year, and there will be fewer heating elements, and the MacBook Pro will be quieter. The problem is that the parts get hot due to dust. If this helps solve the problem, then think about where your MacBook Pro has picked up dust and try to avoid such places, it is in these places that it heats up the most.
If your warranty card has expired, you can find world wide web huge amount interesting and useful information for assembling and disassembling macbook pro.
You can also download special programs, which will check your fans, it will allow you to eliminate all interruptions in the coolers and allow you to adjust your computer against overheating. After installing the program, a temperature sensor should appear in the upper left corner of your monitor; if the temperature starts to creep up, this means that the computer is getting very hot. You can simply increase the speed of the blades. After this, the stuttering will probably be reduced.
If the MacBook first starts to make a very loud noise, and then the system turns off completely, then this matter will be more serious than just cooling. And you will need to contact customer service.
Designers or musicians, as well as gamers, often have this problem. All powerful programs take up a huge amount of resources, after which the computer begins to heat up so much that you can put a mug of water and boil coffee.
In conclusion, I would like to add that the entire line of MacBooks has its minor drawbacks, but in contrast they also have a huge number of advantages, such as the size macbook air, with such size and power - it's worth it.
If your computer gradually but steadily begins to freeze, this will be the first signal to clean the hardware. Download free programs for cooler management, check the temperature conditions, see what the temperature is for all the hardware individually.
If, after installing the programs, the temperature is higher than expected, then feel free to start cleaning it, just do not forget to look on the Internet for instructions on cleaning and disassembling your device. Very important point The point is that if your computer is still under warranty, do not try it yourself, take it to a service center, since if you open it yourself, the warranty will evaporate.
If after heating the system turns off, then you cannot hesitate in this case. Try to make copies of all important data and start cleaning. In fact, you should always check your computer for temperature regime, because if you don’t take care of your device, sooner or later it will malfunction, so go ahead maintenance at least once a year and you won’t have any freezes.
