How to check a cooler on a laptop

Proper operation of the cooling system extends the life of the computer for a long time. If there are malfunctions, the parts begin to overheat and fail. If the equipment began to "slow down" or began to become very hot, then first of all, you should check the cooler on the laptop for functionality.

Program check

The easiest way to find out the cause of the problems and eliminate their consequences is with the help of programs.

BIOS

On many devices, BIOS affects the activity of the cooler. This is especially true for expensive laptops, although there are exceptions.

IMPORTANT! If you have laptops from Acer or MSI, then you should take a closer look at this method.

Turn the device off and on again. Once the boot screen appears, enter the menu Bios. This can be done using the Del, F2 or ESC keys. The combination depends on the model of the purchased device.

Going to the main menu, select the tab Powerresponsible for the temperature of the processor and cooler. Now you need to find CPU Q-Fan Control and CPU Fan Profile. It is important that the first indicator is active. The second parameter is responsible for the fan speed:

• Silent - the minimum amount of charge is expended;
• Optimal - the cooler will start to turn on at the time of increased load on the laptop (often this happens when starting online games);
• Turbo - continuous operation of the cooling system.

For Lenovo owners, this tip may not be relevant.

Using software

You can not go into the BIOS menu and solve a potential problem in the usual way. To do this, you only need the Internet and the name of the desired program.

Speedfan - An excellent application that allows you to determine the performance of the cooler. Download it from an official source and install it on your PC.

As soon as you run the program, you will see what temperature is on the sensors. It will also be possible to manually change the cooler speed setting. To do this, uncheck the box next to "Auto tuning fans" and write the required rotation speed, calculated as a percentage.

If the fixed number of revolutions is not suitable due to severe overheating, you can change the data in the "Configuration" section. The utility will automatically adjust to the selected value.

Another useful application is AIDA64. It is preferable to use for those who are fond of heavy games, especially online.

If the temperature does not exceed 50 degrees, then the cooler is working properly. Exceeding this boundary indicates problems.

Hardware cooler check

You can use the more difficult way - hardware verification. To do this, you have to disassemble the laptop and diagnose the cooler manually.

Be sure to read the instructions before removing the fan. If the warranty has not yet expired, it is highly recommended that you disassemble the laptop yourself. The best solution in this situation is to turn to professionals.

If you do not want to visit the service center, you can make an independent attempt to diagnose it. It is important to know that there is no need to completely remove the cooler. You only need wires to test on another device.

This will require USBwhich has a plug on one side and a second on the other black and red wires. Stick to this algorithm of actions:

1. Connect the black wire of the cable to the black cooler.
2. The red wire must be connected to the red.
3. Insert USB into another device.

IMPORTANT! If the fan began to rotate, then everything is in order with it. Perhaps you just need to clean the cooling system or replace the thermal grease.

To get rid of pollution, it is not necessary to resort to removing the cooler from the laptop case. It is enough to blow it with a can of compressed air (in extreme cases, a vacuum cleaner will also work). If there is too much dust, you can use a brush to remove it.

Then wipe the laptop with a tissue or a cotton swab dipped in alcohol. This will increase the performance of the device even in the absence of a hardware problem.

If the above methods did not give a result when you independently check the cooler for performance, take your laptop to a service center. Professionals will certainly cope with the problem!
