Many users are faced with a situation where the laptop starts to get very hot, makes noise, or suddenly turns off under load. In such cases, the question “how to turn on the cooling” becomes critical to maintaining the functionality of the equipment. It is important to understand that in many modern devices the fan operates automatically, but sometimes its modes require manual adjustment or additional intervention.
The thermoregulation system is a complex mechanism controlled by both hardware sensors and software. If you notice that the device heats up even during simple tasks, it means that the balance between performance and heat dissipation is upset. In this article we will analyze all the available methods for activating and enhancing the operation of coolers, from simple Windows settings to in-depth hardware diagnostics.
Understanding the cooling system in modern laptops
Before you take any action, you need to understand exactly how the system works. thermoregulation in your device. Most modern models are equipped with intelligent controllers that decide when to spin up the fans and when to reduce the speed for silence.
However, automation is not always perfect. Sometimes algorithms delay response to rising temperatures, which leads to overheating processor or video cards. In such situations, the user has to take control into his own hands and forcefully activate the maximum case blowing modes.
The key parameter here is speed control algorithm. It can be hard-coded by the manufacturer or configured through proprietary utilities. Understanding this mechanism will help you choose the right tool to solve your overheating problem.
Using built-in keyboard shortcuts and hotkeys
The fastest way to activate enhanced cooling is to use a keyboard shortcut. Manufacturers often put this function on special buttons that allow you to instantly switch the system to “Turbo” or “Performance” mode.
Typically this function is activated by pressing the key Fn in combination with one of the function buttons (F1-F12). The key body may have a fan or lightning symbol on it. For example, for laptops Asus this is often Fn + F5, and Acer a separate button can be allocated at the end of the case.
- 🔍 Find the fan or snowflake icon on your keyboard
- ⌨️ Press combination
Fn+ corresponding function key - 🌡️ Check the change in the sound background of the device
If your keyboard doesn't have such a button, try looking for the mode switch in Control Center, which is often located on the taskbar. This is the simplest and safest method that does not require the installation of additional software.
Setting the power supply to activate active cooling
Power supply parameters directly affect the operation of the cooling system. When a laptop is in Power Saver mode, the controllers often limit the processor frequency and reduce the fan speed to extend battery life.
To force active cooling on, you need to change the power plan to "High Performance". Go to Control Panel → Power Options and select the appropriate item. This will force the system to keep the processor active and the fans to work harder.
For more fine-tuning, you can open additional parameters for the current plan. Here you will find the "CPU Power Management" and "System Cooling" sections. Set the cooling policy to "Active" so that the system responds to heating by instantly increasing the speed.

⚠️ Warning: Using the high performance battery mode will quickly drain the battery and may reduce battery life by 2-3 times.

Forced control via BIOS and UEFI
In some cases, Windows software settings do not give the desired result, and intervention at the motherboard firmware level is required. The BIOS or UEFI contains low-level settings that control the fans before the operating system boots.
To enter this menu when turning on the laptop, press a special key (usually F2, Del or F10). In the menu, find the section "Hardware Monitor", "Fan Control" or "Power Management". Here you can set the fan curve (Fan Curve), setting the dependence of the speed on the temperature.
Some models, such as gaming laptops MSI or Lenovo Legion, have a special “Smart Fan” or “Cooler Boost” mode, which can be activated directly from the BIOS. This guarantees maximum rotation speed under all conditions.
☑️ Checking BIOS settings
It is worth noting that not all BIOS allow you to change these settings. In corporate and budget models, this functionality may be hidden. In such cases, the only option is to use third-party software on Windows.
⚠️ Warning: Changing settings in the BIOS requires caution. Incorrectly setting the fan curve can lead to fan failure or lack of cooling in critical situations.
Software utilities for controlling fan speeds
If the built-in Windows and BIOS tools fail, specialized programs come to the rescue. They provide granular control over each fan in the system, allowing you to set arbitrary rotation speeds.
One of the most popular utilities is SpeedFan. It reads data from sensors and allows you to manually adjust the speed. There are also proprietary solutions from manufacturers: Armoury Crate for Asus, Norton for Gigabyte or Control Center for MSI.
When using third-party software, it is important to maintain a balance. Too high speeds create enormous noise and accelerate wear on fan bearings. Too low and they will not allow heat to be removed. It is optimal to set up an automatic curve so that the system itself adapts to the load.

Why doesn't SpeedFan see the fans?
This is often due to the fact that modern motherboards use specific controllers that are not supported by older versions of utilities. In this case, it is better to use proprietary software from the laptop manufacturer, since it has drivers specifically for your chipset model.
Hardware cleaning and maintenance of the cooling system
Sometimes the problem is not in the settings, but in the physical condition of the cooling system. Even if you have turned on all possible maximum power modes, dusty radiators will not be able to effectively remove heat. Dust acts as a thermal insulator, blocking air flow.
Regular dust removal is a must for any laptop, especially if it is used in dusty areas. To do this, you need to remove the bottom cover, blow out the radiators with compressed air and, if necessary, replace the thermal paste on the processor and video card.
If the laptop is older than 2-3 years, replacing the thermal interface can reduce the temperature by 10-15 degrees, which will allow the fans to operate in a more gentle mode.
Before disassembling the laptop, be sure to disconnect the battery, if it is removable, or disconnect the battery cable from the motherboard to avoid a short circuit.
If you are not confident in your disassembly skills, it is better to entrust this procedure to the service center specialists. Improperly removing the cover or damaging delicate connectors can result in costly repairs.
Use of external cooling systems
If the internal capabilities of the laptop are exhausted, external solutions come to the rescue. Special stands with active cooling (coolers) can significantly improve air circulation under the device body.
Choose stands with large fans that create powerful air flow. It is important that the stand matches the size of the laptop and has the ability to adjust the angle. This will not only cool the device, but also improve ergonomics.
| Stand type | Number of fans | Cooling efficiency | Noise level |
|---|---|---|---|
| Single fan | 1 | Low (2-3°C) | Quiet |
| Multi-fan | 3-5 | Medium (5-8°C) | Medium |
| Playroom with LED | 5-6 | High (8-12°C) | Loud |
| Vacuum packing | 1 | Very high (10-15°C) | Very loud |
Particular attention should be paid to the vacuum nozzles, which are attached to the air outlet. They create a vacuum, forcing hot air out of the housing. Vacuum coolers can reduce processor temperatures by 15 degrees or more, making them the most effective external solution.
⚠️ Attention: When using vacuum attachments, make sure that they fit tightly to the body, otherwise the cooling efficiency will be zero and the noise will be maximum.
A comprehensive approach, including software settings, regular cleaning and the use of an external stand, provides the best results in combating overheating.
Frequently Asked Questions
Why does the fan run at full speed all the time?
This may indicate a critical temperature sensor error, processor overheating due to thermal paste drying out, or a controller malfunction. Try updating the chipset drivers and checking the temperature with AIDA64.
Is it possible to turn off the fans completely for silence?
Strongly not recommended. A complete shutdown will lead to instant overheating and emergency shutdown of the laptop or failure of components. Use Silent rather than Off modes.
How do you know when it's time to change thermal paste?
If the temperature at idle exceeds 50-60 degrees, and under load it quickly reaches 90-95 degrees, and cleaning from dust did not help, then the thermal paste has dried out and requires replacement.
Does the angle of a laptop affect cooling?
Yes. The raised rear edge of the laptop allows for better air access to the bottom vents, which can reduce temperatures by 3-5 degrees at no extra cost.
What to do if the laptop does not turn on after overheating?
Allow the device to cool completely for 30-60 minutes. If this does not help, the protection may have been triggered or a failure has occurred. Try resetting the BIOS settings or contacting service.
