How to Change CPU Fan Speed Without BIOS? ( Within a Minute)

Changing the speed of the CPU fan isn’t a big deal. You can do it whenever you feel your system needs it. For instance, if you are experiencing overheating in the design, you have to increase fan speed to keep the system stable. On the contrary, it can also happen that your fans run at full speed without any apparent reason. So, in this case, as well you have to modify the CPU fan speed. Undoubtedly, using BIOS for changing fan speed is the easiest way. But unfortunately, sometimes the BIO doesn’t offer you to do so. Therefore, today we enlightened the subject “how to change CPU fan speed without BIOS.”

Two effective ways allow you to make changes and control CPU fan speed without using BIOS. Below are the names of these methods; kindly have a glance at them.

  • Fan Control Software
  • External Fan Controller

Forgoing in the details of these procedures be connected with the post until the last. Thereby, you can understand very comprehensively how to adjust the fan speed.

How to Control Fan Speed on PC by using Fan Control Software Method?

Nowadays, you can find many fan control software such as HWMonitor, Corsair Link, Argus Monitor, Notebook FanControl, and SpeedFan. Among them, we use the SpeedFan software to adjust and change the fan speed.

Speedfan is Microsoft Windows software that is available for free. The program is made to monitor the temperature of components and the fan speed of the CPU. You can manually adjust fan speed with this PC fan controller software if you want. Apart from this, you can also utilize its automatic features for fan speed. This feature automatically reads the components’ temperature and handles it along with fan speed according to the need.

SpeedFan is the famous software for controlling the fans. It might be a typical design it looks typical, but it works fine. For setting the software, one has to acquire proper knowledge, especially if they are beginners. Therefore, follow the steps described below:

First Step: Download and Install the SpeedFan

Go to the official website of SpeedFan. Download the software given there; when it will download, start the installation process; once the application installs in your windows, open it to scan the buses on the MOBO.

Second Step: Fan Control Configuration

Don’t attempt to make changes in the fan speed with PWM when you open the application. Firstly, you need to configure it precisely.

  1. You will see a suggestion of “Configure” click on it.
  2. Afterward, an option of “Advanced” pops up on your screen. Click on it.
  3. Now, you have to press on the “Chip” given in the dropdown menu.
  4. Find the PWMs in the menu. If you have no idea about the location of PWMs, then click on all the chip dropdown items.
  5. When finally you find the PWMs, then choose the ones that you want to handle.
  6. Once you choose it, a “set to” popup dropdown.
  7. The two options “Manual” or “Software-controlled” will appear.
  8. For handling the use of software, you need to select “software-controlled.”
  9. Don’t forget to click on the “Remember it” to save the user settings in the future.
  10. Return to the Main Window and choose among PWM1, PWM2, PWM3, PWM4, PWM4, PWM5 that you have configured.

Third Step: Automatic Fan Control Set-up

In the previous step, you learn how to change the fan speed manually. For an automatic fan speed control, you need to set it up properly. So, whenever a CPU gets overheated, it automatically increases CPU fan speed. In contrast to this, when it cools down once, it will automatically decrease the rate.

  1. For this, you have to click on “Configure” and then go with the “Speeds” tab. For determining the minimum and maximum range of RPM for your fans.
  2. Once you set up RPM, then go ahead to the “Fan Control” tab. By this, you can set up and determine a suitable temperature curve.
  3. After setting the temperature range, now it’s time to examine its effects on the system. For reviewing whether the changes are favorable or not, try to load some heavy apps.
  4. Now, open the “temperatures” tab to set and determine when your CPU fan speed increases and decreases depending on the CPU/GPU temperature.
  5. Then, in the temperature configuration menu under all the sensors, select the determined sensor for controlling them.
  6. At the bottom of the screen, you find two choices: “Warning” and “Desired.”
  7. Set both of these options to your required choice.

The only thing now you have to do is go with “Apply” and then “Ok.” Whenever your CPU/GPU reaches a defined temperature that you have set, it will automatically slow or fast the speed. That’s how you can use this Fan Control Software for PC fan setup.

How to Control CPU Fan Speed with External Fan Controller?

Don’t worry if the first method doesn’t resolve the problem. Still, you can go with an external fan controller. By doing this, you can utilize the full power of the fans. Sadly, the Speedfan is not compatible with some motherboards, so that you can consider an external fan controller such as CORSAIR COMMANDER PRO or Thermaltake Commander F6.

However, the Commander 6 is an immensely popular external fan controller. It consists of the three socket pins that enable it to control the six fans at one time. To note the temperature and fan speed, an RGB LCD is already equipped. Also, it comes with a warning alarm, six temperature sensors, six control knobs, and short circuit protection.

How to Control Fan Speed in BIOS?

If you want to use BIOS for changing fan speed, then follow the following steps:

How to Control Fan Speed in BIOS
How to Control Fan Speed in BIOS
  • Restart the PC once it boosts up, press and hold the “F12” or “Delete” key to enter the BIOS.
  • For locating the fan speed control, use the keyboard arrow keys. Open the option Monitor then Status, and then you find fan speed control.
  • Check the RPM settings, and choose the fan whose speed you want to increase—define the RPM and press Enter. Repeat this for applying it on all the fans.
  • Tap on the key “Esc” multiple times until you see an “Exit Menu.”
  • Remember to confirm the “Save Changes and Reset” option.
  • You are all done.

How to Change the Fan Speed of Windows 10?

You can change the fan speed on Windows 10 precisely the way we described it in the post. All the details are applicable on Windows 7, Windows 8.1, and Windows 10.

Conclusion How to Change CPU Fan Speed Without BIOS?

A need to adjust the fan speed of the CPU can occur at any time. Nonetheless, it’s an essential thing for the health of PCs. That’s why it would be better if you already knew how to increase the fan speed when the CPU overheats with or without BIOS. BIOS often doesn’t work; therefore, we significantly mentioned two helpful ways to change fan speed without BIOS. You should carefully read this guide about “How to Change CPU Fan Speed without BIOS” especially if you are a newbie.
