How to start the cooling fan forcibly

At what temperature does the cooler on the laptop turn on

With active use of laptops, especially in the hot season, users are often faced with their strong heating. Systematic overheating leads not only to the slowing of the operating system and periodic shutdowns, but also to the premature failure of the processor, motherboard or other structural elements. To reduce the temperature of the laptop, you can forcibly turn on the fan, which is part of the cooling system of the laptop, by changing some of its software settings.

In notebook computers the BIOS is responsible for the proper functioning of the cooling system. The fan, however, is factory-set to run only at 50% of its maximum capacity. This is done to ensure that during operation the cooler does not whirr strongly and does not consume much electricity.

On almost all motherboards there is a possibility to control the cooling system’s functionality by software. Forcing the fan on your laptop computer can be done in several ways:

Changing the settings of the cooler can cause unpleasant noise during its operation, as well as accelerated drainage of the battery. So before you proceed to radical measures, you should disassemble the laptop, and then clean the fan and the motherboard from dust, because it reduces the heat output and, accordingly, leads to an increase in temperature PC.

How to turn on the fan on the laptop

The fan on the laptop is needed in order to reduce the temperature inside the device. So when the weather is hot, or with high loads, the device may freeze and malfunction. In the processor and other stuffing is built in protection against high temperatures, so they do not overheat and do not spoil. So if the device overheats, it can even shut down spontaneously.

One available option is to buy an external stand with a cooler. But this is not always convenient, especially if you move from location to location.

However, the cooler, built into the notebook chassis, can be adjusted programmatically. That is to increase or decrease its speed, turn it on or off forcibly.

Ways how to turn the fan on Lenovo notebook, are described below:

  • Through the BIOS settings. in those models that support it.
  • Using special software. the most popular software is SpeedFan.
  • On some Lenovo models. using a shortcut key. For example, for Lenovo Y530 it is a combination of FN Q.

Lenovo laptop fan control will be described in more detail below. However, before you start manipulating the cooler, make sure that there is nothing wrong with it. To do this, follow these instructions:

  • Check that the fan works, and that there was no technical defect during its installation, that is, the polarities were not mixed up. To do this, bring a string or light lint to the holes. They should flutter away from the device. If they do not move or stick to it, then it is not okay. Naturally, in this case, the computer must be turned on, and even better, that a productive program, such as Photoshop or a game is running.
  • Check that the power settings allow for full operation. To do this, go to Control Panel. “Power” or enter “power supply” in the search box next to the Start button. Next you need to “Configure Power Scheme”. “Change Advanced Settings” and go to “Processor Power Management”. Next, go to the System Cooling Policy and set both settings to Active. Save your changes.
  • Make sure that the fan is not clogged with dust and dirt. Often this reduces its speed, does not allow the system to cool fully. To do this you need to remove the bottom lid of your notebook. Carefully unscrew all the screws from the bottom, remove the cover and examine the view of the open part of the stuffing. Large amounts of dust and dirt will undoubtedly decrease productivity and increase the temperature. Gently wipe the internal parts and the cooler itself with alcohol and a soft synthetic brush.
  • You can also blow out the fan on your Lenovo laptop. You will need source of compressed air, such as a can of compressed air or a blow gun. This way you can get rid of dust faster.

There are also other programs allowing you to forcibly start your notebook’s fan. So, with AMD OverDrive utility you can modify PC cooler operation based on AMD CPUs. Riva Tunes application developed for Intel processors.

When actively using any laptop, particularly in the summertime, their users can often face the problem of overheating. Such an “embarrassment” can lead not only to minor slowdowns of the operating system, but also to damage the main parts of the system unit. the processor (read our article about what processor temperature is considered normal), graphics card and motherboard. In order to reduce the temperature inside the laptop can be forced to turn on the fan when necessary. Read our article on how to do it.

Please note that before you perform any manipulations with the laptop, you must first make sure that the cooler as a whole works. Also do not forget to check the fan for contamination, because because of the excess accumulated dust debris can interfere with the operational work of the blades.

How to turn on the fans on your computer

The system units of stationary computers have special fans. Their primary purpose is to provide cooling for important PC devices. It is extremely important to monitor the temperature of the equipment to prevent its failure as a result of overheating.

Begin by determining why the fan ceased to operate properly. Turn off the computer and disconnect the power cord. Gain access to the inner workings of the PC by removing the left cover from the case.

Verify that the unit is plugged into the power plugs. These are usually located on the hardware to which the cooler is attached, or on the computer’s motherboard.

Check the quality of the lubrication of the propeller shaft. To do this, turn the blades with your fingers and make sure they rotate freely. If not, replace the cooler or try changing the lubricant.

If the problem is not a technical issue, check the fan settings. The first sign of a bad configuration is that all the coolers of the computer turn off. Turn the PC on and enter the BIOS menu. Hold down the Delete key for this purpose.

start, cooling, forcibly

Go to Advanced Settings menu and find the item that has the words Cooler or Fan in its name. Set the selected item to Always On. If your motherboard BIOS allows you to set the fan speed manually, activate the 100% option.

Save your settings. Reboot the PC and check the fans. If the coolers are still not spinning, download and install the Speed Fan program. Open this utility and wait while it collects information about the available fans.

Set the speed for each displayed cooler to 100%. Disable AutoSpeed. Save your settings. Try to decrease the fan speed. Insufficient voltage to the coolers may be the cause of the problem.

Set the fan to 20-30% of its maximum speed. Replace the fan if all these actions do not help.

What is Fan Always On?

A firmware update has been released to enable the Fan Always On option in your BIOS. This BIOS update prevents your computer from heating up during normal use. This update applies to computers that have BIOS version F. 04 and earlier.

Ways to control the fans

The fan is factory set to run at 50 percent of its capacity. This is to reduce noise and power consumption. This is usually sufficient to prevent overheating. You can also turn it up higher if necessary.

The number of revolutions is adjusted by the BIOS. This value can be changed by the user here. In addition, you can control the cooler and turn it on at full power by using special programs or standard means of the system.

Before you increase the power of the component, it is worth to clean the laptop from dust. Contamination is often the cause of rapid heating. To do this you will have to disassemble the laptop. If you do not have such skills, it is better to contact the professionals.

Forced start in BIOS

The first way to force the fan is to change the BIOS settings. First the user needs to reboot the laptop. During start-up you should press the combination of keys to enter BIOS, which may vary depending on the version.

Blade rotation settings are in the Power section, here you need to select the Hardware Monitor command.

In the open window, you need to specify the power of the cooler in the percentage. The best option will be if the system independently adjusts the indicator, depending on the heat of the central processor.

After entering all the parameters, you need to save the changes. The laptop will be reset and fan will work with more power.

SpeedFan software

You can also force the fan to max out using Speed Fan app. The program has a simple interface and the Russian localization. In addition, it is completely free of charge. To change the fan power you need to follow the instructions:

System tools

The Windows operating system allows you to configure the cooler via the standard settings. To do this, you need to go to the control panel through the settings and follow the sequence of actions:

There are two ways of running the cooler, active and passive. To force the activation, select the first method and save the changes.

Solution Ways

The functionality of the cooling system depends entirely on the BIOS. Keep in mind that the factory default setting is not to run the cooling system at full capacity, but at only 50 percent to minimize power consumption and noise emissions. Almost all motherboards have the ability to control the coolers with special programs.

You can use one of the following ways to forcibly turn on the cooler in your notebook:

Changing the settings may cause additional noise and increased power consumption. That is why you should first disassemble and thoroughly clean the laptop, including the cooling system, from accumulated dust, which may be the original cause of overheating.

All methods described below are equally suitable for laptops of different manufacturers (Samsung, HP, Asus, Lenovo, etc.).)
