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.
The main reason is the lack 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 encounter this, this material should help adjust the operation of the 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, a 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 system processes that load the processor are partly to blame. 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. The MacBook may make more noise, but it will last longer.
Cooling MacBook on Windows
Problem: MacBook's built-in coolers turn on either too late, or work at high temperatures not intense enough. We wish the automatic control system 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.
On 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 is the overall temperature of the processor, which means that 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, most modern Intel processors 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.

It's better to take it to a service center. And ask that they do it carefully and in front of you.
Precautionary measures
You shouldn't 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 you have personal experience with setting it up, feel free to comment.
During operation, any computer generates heat and this is an absolutely normal process. As long as temperatures do not exceed acceptable limits, you don’t have to worry about the condition of the iMac all-in-one. You can determine that the iMac 27 is heating up above the permissible limit by listening to the cooler. It will produce increased noise. In addition, the iMac case will become hot.
It is recommended to solve the problem promptly, since overheating may subsequently negatively affect the operation of the battery and video chip. Before you begin repairs, you need to determine the cause of your iMac overheating. This will be discussed further.
What causes the iMac 27 to heat up?
Excessive overheating can be caused by a clogged cooling system. Moreover, the degree of clogging is practically independent of operating conditions. During operation, the fan draws in not only air, but also tiny particles of dust that settle inside the case on the motherboard and clog the coolers. This prevents the iMac's internal chips from cooling, causing them to overheat and fail.
In order to return the monoblock to working condition, you will need to clean the entire cooling system. Typically the process takes about two hours. It is not recommended to clean it yourself, since the design of the monoblock is not designed for disassembly at home. In addition to a set of special tools, you must have experience in such work in order not to damage the monoblock and protect yourself from subsequent repairs, which will be expensive.
Another reason why the iMac 27 gets hot is because all of its internal components are tightly packed. This configuration model is designed specifically to make the monoblock light and compact. With proper use, overheating can be avoided.
iMac 27 is heating up: measures to help avoid the problem
As mentioned earlier, the iMac can overheat due to its own configuration, or more precisely, due to the dense arrangement of its elements. If your iMac 27 gets hot, it's worth paying attention to how you use it.
- Close unnecessary applications that weigh a lot. You can find them through “System Monitoring”. Such applications load the processor and generate a lot of heat. As a result, the iMac 27 heats up and performs operations that are not currently needed.
- Keep your temperature under control. Special utilities will provide detailed information about all system parameters - cooler speed, “heavy” applications, sensor temperatures.
- Position the candy bar correctly. If placed in the wrong location, the iMac 27 will become hot and may fail. Avoid poorly ventilated places and do not install the monoblock in cabinet niches, close to the wall, or next to heating appliances.
- Perform preventive maintenance regularly. Any problem is easier to prevent than to fix. Timely cleaning and replacement of thermal paste will protect the monoblock from overheating. It is recommended to clean the monoblock once a year with soft brushes.

Do you notice that your iMac gets very hot during use? The main reason why a computer overheats is a clogged cooling system. If the radiator is clogged with dust, then this phenomenon is quite possible.
At the same time, the degree of clogging of the cooling system is almost not affected by the operating conditions of the equipment. Sooner or later, so much dust accumulates in the system that the iMac is no longer able to cope with cooling during operation.
In order for the iMac to stop overheating, you need to clean all parts of the cooling system from dust and dirt, and also change the thermal paste - the layer between the microchips (processor) and the silicone pad of the radiator. There comes a time when the thermal paste “dries out”, so it needs to be replaced with new one. Part of the reason the iMac runs hot is because the thermal paste dries out and loses its physical properties. The factors of temperature and time do their job.
If you are faced with the fact that your iMac gets very hot during operation, then contact a service center. Here you will be provided with professional advice and the problem will be corrected.
Good day, I decided to tell you why the Macbook is heating up and give some tips so that you can avoid problems in the future and nothing interferes with your work comfortably.
1. The main reason why, in principle, MacBooks “like” to get very hot is the monolithic body without technological holes for air intake on the back surface of the laptop. This is done in favor of the stylish design that we love so much. Air is taken in from the right side through two narrow holes, and discharged using a special air vent on the rear end of the MacBook, in the place where the screen is attached. The solution to this problem is simple. Buy a cooling pad with two or more coolers to evenly cool the bottom surface area of the laptop. If the budget does not allow, simply place the Macbook, for example, on matchboxes, so that there is free space between the bottom and the surface on which it stands.
2. Users I know often ask me the question: “Why does my MacBook get hot under low load?” My answer is: this is an accumulation of dust inside the case and in the cooling system. Accumulated dust on internal circuit boards causes strong heating of all elements, and dust in the cooling system interferes with the removal of excess heat from the already excessively overheated elements of your device. The solution at first glance is simple, but it requires you to have the skill of opening the bottom cover and carefully removing dust from all elements and coolers. If your Macbook is still under warranty, then it is better to take it to an authorized service center so as not to lose it.
3. There is another reason why the MacBook gets hot. One of Apple's main ideologies in designing a laptop is not only its laconic design and compactness, but also its quiet operation. Therefore, the fans operate until the last minute at a low speed of 2000 RPM (revolutions per minute). They accelerate to maximum speed only when you can warm your hands on the body of the device in the winter cold. The solution this time is more complex, but with the proper desire you can easily master everything. You need to download one of the many programs on Macbook, for example smcFanControl. It's easy to use and free. You will always be able to see the temperature of the central processor and at the appropriate moment increase the RPM yourself.
4. The last reason why a Macbook gets very hot is the heavy load on the CPU and video card. When working with “powerful” programs that load hardware, such as video editing and computer games, a large amount of heat is generated and, as a result, the entire system heats up. To smooth out the consequences, use all the tips I listed above. It also helps in such cases to install additional RAM, for example two 8 GB sticks. This reduces the number of accesses to the hard drive or SSD, and, accordingly, strong heating.
As a bonus, I’ll tell you another way to reduce the temperature of the central processor by about 10 degrees. The point is to reset the System Management Controller (SMC). Perform this procedure no more than once a month. Simply disconnect the Magic Safe (charging plug), turn off the MacBook, insert the Magic Safe back, and press the Shift + Control + Option + laptop power button together for a couple of seconds. In this case, when you press these keys, the indicator will blink green, but the Macbook will not turn on.
In the case when the green indicator was on, the color of the indicator will not change. Press the power key - the system will boot, then just enjoy the result.
In conclusion, I would advise you to always update to the latest version of the system. Now you know why your MacBook is noisy and hot.
