How to Change CPU Fan Speed Without BIOS, How to Control CPU Fan Speed, How to Manually Control Your PC Fan

Not all systems are always equipped with a CPU cooling fan. It’s a good idea if it’s present, but keep in mind that your computer will not always need it. But if you have the option to install the fan, then go for it. It’ll be worth your effort.

You may have heard of this happening before: gaming or using demanding software tends to make your PC overheat, and sometimes it happens when nothing particularly stressful is going on at all. There are three main issues that develop without a controllable CPU fan.

If you’re having trouble changing the speed of the CPU fan, here’s how to change CPU fan speed without bios.

Use Fan Control Software

Although you can adjust your computer’s fans manually, it’s better to use an automatic option. The best way to get the most out of the vents on your computer is by using fan-controlling software.

This type of program will monitor your CPU for fluctuations in temperatures and adjust the blower speed if you find that you need more air flow. When there’s too much heat in your system, the program will keep tabs on it until things return to normal.

Automatic programs are very user-friendly because they don’t require direct interaction once installed. Trying to make sure your PC is compatible with the Windows 10 operating system as well as other components such as the CPU can be difficult.

But if one must look for fan controller software to help cool their hardware, SpeedFan might be a good place to start because it’s supposed to work just fine within that system.


If your BIOS doesn’t allow you to adjust the speed of your blower fan, don’t panic. There are ways to modify the way your CPU fans work. One such method is using one of the many simple utilities available today. SpeedFan is a free utility that will give you more advanced control over how your CPU fans operate.

SpeedFan is a CPU monitor. It’s a useful tool, but you need to check if your CPU has the right equipment to run properly before you download the software.

Step 1: Download & Install SpeedFan

To use SpeedFan, you will need to download it and install it just like any other program. Make sure to read the installation instructions that come with the download and follow them closely so that you can avoid any technical difficulties that might occur along the way.

Once the software is installed, simply start it up and allow it to scan so that it can display all of your computer’s details in the main window. The main window will provide you with information such as your processor speed, graphics card speed, hard drive speed, and much more.

Make sure you know the different buttons and what they represent. Avoid pressing buttons if you are not sure what they do. If you are familiar with it, proceed to Step 2.

Step 2: Play With Some Fan Controls

We know we mentioned this earlier, but we want to be sure we give you the full scoop so you aren’t disappointed. The SpeedFan program can sometimes really complicate things when it comes down to making it work just right, and with the speeds not always matching with what you might expect them to be in some instances.

It can quickly become a hassle if it weren’t for the ability to manually change settings yourself depending on an array of conditions that will help ensure your PC runs at maximum efficiency and performs like an international racing machine.

So without further ado, click Configure and choose Advanced and then click either your motherboard chipset or newer processors, if you need action; They will likely both be listed in their own little category, which is great because they will likely require tweaking until they pull through.

Click the drop-down menu box, select all options (and make sure they are set to manual) and adjust accordingly for optimal results.

Note: Make sure to check or tick the box that says remember the setting and click the OK button.

Step 3: Set Up Your Automatic Fan Control

To set the minimum, and maximum RPM of your fans, navigate to the “Speeds” tab after clicking the configure button. Once you’ve done this, click on the “Fan Control” tab and set an ideal temperature dependency for your CPU fan.

This will help you monitor whether your adjustments have any effects. You can choose to initiate a demand request to test out this conversion process and see how it works. Be sure to save all of these changes or else you will need to repeat this process every time you restart your computer.

Finally, move over to the local machine side so that your CPU fan will respond more appropriately as far as heating up is concerned. Make sure you select the sensor that controls the processor as its default one, as this is essential as well as equally necessary in making things work accordingly thereafter.

Now you can use the arrow keys to set the desired temperature and what your PC should do if it rises above or drops below that temperature. For example, if you want your PC to shut down if it exceeds 104 degrees Fahrenheit, then set that as the “action” to take by clicking OK.

This will protect your PC from overheating which can lead to permanent damage. It’s important to note that this software may not support all PCs, but there are other alternatives which you can find below.

NoteBook FanControl

A notebook fan controller is used to control the speed of computer fans. This software is user-friendly as it includes a simple interface with the availability on the taskbar after install. It’s very straightforward, allowing newbies to manage it. To check whether notebook blower speed control Windows 10 supports your laptop, then go to GitHub’s official page.

Check out the key features included in the notebook fan control software.

  • NoteBook Fan control software provides current fan speed and real time CPU temperature.
  • The simple sliders in the middle of the menu allow controlling the fan-speed.

Use External Fan Controllers

Use External Fan Controllers, computer, technology, equipment, color, blue, fan, power, inside, design, parts, wires, hardware, pc, electric, cooling, temperature, cooler, processor, component

You can change your CPU fan speed without BIOS by using a thermal paste and cooling system, but you can also use an external fan controller and take advantage of the full potential of your fans.

Speed fan does not work with some motherboards so you can use an external fan controller like Thermaltake Commander F6 or Corsair Commander Pro. The External Cooling System does not have a USB connection, so it needs to be connected directly to a motherboard fan controller slot.

Thermaltake Commander F6

Commander F6 is an external fan controller that allows you to monitor and control six fans. It has three pin sockets and can monitor six fans simultaneously. The device has an LCD screen which can display temperature and fan speed; it also comes set with six control knobs and a warning alarm with short circuit protection.

FAQs ― How to Change CPU Fan Speed Without BIOS

How do I change my CPU fan speed manually?

The easiest way to manually control CPU fan speed is to adjust the BIOS fan settings. Select the “Fan Speed Control” option from the “Monitor,” “Status” or other similarly named submenu (this will also vary slightly by manufacturer) to open the fan controls.

How do I adjust my CPU fan speed on Windows 10?

  • Open up the sub-menu and select “System Cooling Policy.”
  • To adjust CPU fan speed, select the option “Active” from the Dropdown menu.
  • In the end, click the “Apply” button to save all of the changes.

How do I manually control my fan speed?

To increase fan speed, look for a system configuration option, navigate to it (usually using the cursor keys), and then look for a setting related to your fan. On our test machine this was an option called ‘Fan Always On’ which was enabled.
