How do I adjust the CPU fan speed without accessing the BIOS? Today, we will provide a thorough response to this question.

If your computer is overheating, you must speed up to cool down the CPU. In any case, overheating isn’t the only reason you need fan speed control. If your fans are running at full speed for unknown reasons, you may need to slow them down using one of the methods described in this article.

Changing the CPU fan speed through BIOS is probably the best way, but it isn’t always possible. If you’re having a similar issue, you have two choices for controlling your fans without using BIOS.

Fan control software

It is available in a variety of forms, including Corsair Link, Notebook Fan Control, Argus Monitor, Speed Fan, and other similar applications. Each of these options is acceptable; however, in this article, we will demonstrate how to configure Speed Fan to control fan speed in Windows.


Microsoft Windows speed fan is a free program that displays fan speed as well as CPU segment temperatures. In addition to manual fan speed control, it also has a programmed fan speed feature, which monitors the temperature of the segments and adjusts the fan speed as needed to keep them cool.

Note: Speed Fan is arguably the most well-known fan control programming; while its design may appear dated to you, it is far from being a free program created by a single individual or group. For beginners, setting up the product can be challenging, which is why we recommend that you carefully follow the instructions provided below:


Installing Speed Fan is as simple as downloading the installer. Whenever it has been downloaded, run it by introducing it and then opening it. The application will begin filtering all of the transports on your motherboard as soon as it is launched after it has been launched.

When you first open the product, do not attempt to change the fan speed using the PWM controls because you must first design the fan speed before proceeding.

  • Select “Design” from the drop-down menu, and another window will appear.
  • Now, select “Cutting Edge” from the drop-down menu.
  • Following the selection of “Cutting edge,” you must select “Chip” from the dropdown menu that appears.
  • In the menu, look for your PWMs (if you don’t know where your PWMs are, try tapping on all the chip dropdown things to see if you can find them).
  • When you’ve discovered all of your PWMs, select the ones that you want to be in control.
  • Following the selection of the PMW, you’ll be presented with a “Set to” dropdown menu from which you must select either “Manual” or “Programming controlled.” (This will allow Speed fan to control the fans in your home.) Make sure you click on “Recall it” to save your settings after you have finished.
  • You can now return to the main window, where you’ll see PWM1, PWM2, PWM3, PWM4, and PWM5 as well as the rest of the controls. Select the PWM that you previously configured, and you can now change the fan speed by physically typing or using switch catches.
  • The third strategy is to put everything on autopilot.
  • In sync 2, we clarified how you can control fan speed; however, this is a manual process. You can also set up programmed fan control so that if your CPU starts to overheat, Speed fan will automatically increase its speed, and when it becomes cool, it will decrease its speed
  • It is possible to set up programmed fan control by tapping on “Arrange,” and then clicking on “Fan control” and checking the progress of the programmed fan control. As it is, we believe that explaining everything here will be too confusing, which is why we have included a YouTube video at the bottom of this page. It will assist you in accurately setting up everything.


External Fans

Have you exhausted all your options and are you still pondering how to reduce the speed of your computer’s fan?

Indeed, you should consider using an External Fan Controller to control your fans. Having a fan speed regulator allows you to monitor the temperature of your computer and physically change the speed of your fans.

Even if the time you have is significantly longer than that of other pc fan regulators, you will assist your framework in achieving the ideal balance of peace and cool.

When selecting a PC fan regulator, take into consideration the feel of the device, its pin backing, its controls, and its channel configuration.


Purchasing a fan regulator is a smart move if you require more control over your CPU fan and other components of your framework than you currently have. Cases such as NZXT’s H-series I forms include an integrated connection box that allows you to program your CPU fan in a manner similar to Speed fan, but in a more natural way. It also adds support for RGB lighting as well as a variety of fans’ designs, profiles, and bends to the game.

The use of independent fan regulators can provide you with more comprehensive control. Some, such as the Thermaltake Commander FT, provide touchscreen controls for the various fans on your framework, whereas others have physical handles and dials that you can use to control them.

You’ll need to follow the instructions provided for those, as their arrangement and the executives’ involvement are important to their individual plans.


check your hardware

To determine whether you need to replace your fan regulator, you’ll need to open your computer and check a couple of things. To begin, you’ll need to determine how many fans your computer has in order to purchase a fan regulator that can support each and every one of your fans simultaneously. Furthermore, you’ll need to disconnect all the fans from the motherboard so that you can determine whether they use 2, 3, or 4 pin connectors. When purchasing a fan regulator, you’ll need to be aware of the type of connectors that your fans employ.

When dealing with something on your computer, make sure to touch something metal to ground yourself properly. This prevents static discharges from occurring, which can be harmful to your computer. It’s possible that you’ll need to purchase a couple of static wrist groups to wear while working on your computer. The tiniest static release can demolish your computer’s operating system.


You can purchase a fan regulator either online or from a computer store. Make certain that the fan regulator you purchase can support all of the fans in your computer and that it has the appropriate pin connectors. Many fan regulators require a readily accessible space in the drive cove of your PC tower to function properly.

If your computer’s fans are equipped with 2 or 3-pin connectors, you may be able to upgrade to new fans that have 3 or 4-pin connectors as a part of a system upgrade. Two-pin connectors only record the amount of electrical current flowing to the fan. The fan’s speed can be controlled through the use of 3-pin connectors. Beat wave balance (PWM), which controls the fan power by sending capacity to the fan in beats, is added by using four-pin connectors.


Check to see that your computer has been completely shut down. Remove the force link from the system at that specific time.

4: Remove the Cover to Allow for an accessible drive-cove extension opening.

A free drive straight development is required for most fan regulators in order to properly introduce the fan regulator. This is the location where a DVD/Blu-ray drive would be installed on a consistent basis. Follow the instructions in the user’s manual for your computer to remove the cover from the extension inlet, where you will be installing the fan regulator.

5: If Needed, Interface the Warm Sensor.

Not all fan regulators are equipped with a warm sensor connection. If yours has a warm temperature sensor input, disconnect the warm sensor from the motherboard and connect it to the fan regulator to complete the process. If the fan regulator comes with its own set of warm sensors, make sure to follow the instructions in the user’s manual to ensure that it is properly installed.

6: Connect Your Force Supply to Your Fan Regulator.

Connect your force supply to your fan regulator using a connector.

Depending on which fan regulator you purchase, the method by which you interface capacity to the fan regulator will differ. Only a few fans have a force input that can be used to connect a link from your power supply to them. [10] The information and yield association for each fan control may be included in more basic fan regulators. As a result, connect the fan regulator to one of the fan outputs on the motherboard using one of the connection links that came with the fan controller. It should then be interfaced with a contribution on a fan controller at this point. Check to see that the yield on the fan regulator is associated with the fan that you want to control with the handle. a.

An adapter to connect a Molex link from your power supply to an information association on the rear of your fan regulator may be required from time to time.

Test the Fan Regulator.

Feel free to use your PC to control everything whenever it is snared. Check to see that all of the fans are operational and that you have the ability to change the settings on them by using the fan controller. Making modifications as necessary and consulting the client’s manual if you are unsure of why something isn’t working is recommended.

Set Up Your PC Back

You can reassemble your computer once you are certain that everything is functioning properly. Place the fan regulator in the extension inlet and secure it with screws or the mounting framework that your computer employs to prevent it from moving around during operation. Reinstall the sideboard of your computer and secure it with screws at this point.

Questions that are Regularly Asked How do I manually change the Speed of my Internal Processor Fan?

The bolt keys on your console can be used to move around in the BIOS menu to find the “Screen,” “Status,” or other correspondingly named submenus (this will likewise differ somewhat by the producer). To access the fan controls, select the “Fan Speed Control” option from the submenu.

Is it possible to increase the speed of the CPU fan?

Please scroll down to the section titled “Fan Speed Control.” The RPM settings for the computer fans are contained within this section. To turn up a fan, select the one you want and press the “Enter” key. To save the setting, select the desired speed from the drop-down menu (for example, “400 RPM” or “500 RPM”) and press “Enter” once more to confirm your selection.

What is the best way to change the speed of my CPU fan in Windows 10?

Speed Fan is a Windows 10 application that allows you to control fan speed. Speed Fan should be installed and run. Using the Design button on the application’s main window, you can create a custom design. It will open a new window. Select the Fans option from the drop-down menu. Allow the application to discover and list your followers while you wait for it to happen. Choose the fan that you want to control. Alternatively, click here. The fan speed can be controlled by utilizing the reaction bend.


Adjusting fan speed can be done through the BIOS, a third-party fan controller, or a dedicated external fan controller.
