Whether your fan is spinning too fast making a loud noise or too slow causing overheating problems, you may want to control the speed.
Since PC fan work is related to system temperature, you need to adjust it voltage or pulse (depending on your fan type) to change the speed manually. Let’s look at different ways to do this.
Use Fan Utility in BIOS
Let’s start with the simplest but effective technique. If you are trying to change the computer case fan speed or even adjust the CPU fan, you can do it directly from the BIOS utility. Just understand this way–only the connected to your motherboard which can be controlled using the motherboard firmware.
I’m mainly talking about PWM (which has four pin) and DC fans (which have three pins). The former offers much more precise control by adjusting the duty cycle (in percentages). On the other hand, DC fans run over a wide range of voltage levels, which is relatively difficult to control.
Before anything else, make sure your PC’s fans are connected to their respective headers. Your case fan is usually located in SYS_FAN or CHA_FAN, and the CPU fan in the CPU_FAN header.
Now that you know the basics, let’s cover the following points to understand how to control PC fans in BIOS. Note that the exact steps vary for different motherboard manufacturers and models. So, the following instructions will only give you a basic idea:
First of all, start/restart your system and enter the correct key for access the BIOS interface when the PC does the POST. It can be the F1, F2, F7, Del, or Esc key depending on the manufacturer and model. Depending on your motherboard BIOS, find and open the custom fan utility. This may be Smart Fan Mode, Hardware Monitor, QFan Setup, Fan-Tastic Setup, etc.
Although different motherboards have different names, they offer the same features–adjusting fan speed, setting up a manual fan speed curve, applying control modes, or even setting a minimum duty cycle. Once on the custom page, you can now choose automatic or manual fan speed control.
You can immediately select one of these options–Normal/Standard, Silent, Turbo or Full Speed based on your preference. The first two usually make the fan run slower while the last two will increase their RPM. Some motherboards even support the feature automatic fan adjustment. For example, ASRock Fan Tuning lets you detect the lowest fan speed and adjust accordingly minimum duty cycle automatically.
Interestingly, some modern Intel-based ASUS models (having the Z690, B660, Z590, and Z490 chipsets) offer an option called AI Cooling. It sets optimal settings based on current temperature and system load. To manage fan speed based on source temperature, most modern motherboards support Fan Speed Curve.
You can tweak nodes/points to plot custom curves. When you do, set the mode to PWM if your fan has four pins and DC if it has three. If you want to change the fan speed to default value, there should be a special option for that. Additionally, you’ll need to find individual columns to run the fans on Full RPMs or delete the newly set configuration. Once you have adjusted your fan speed setting, make sure you save it before exiting the BIOS.
We have prepared a special guide that will help you to change the fan speed in several popular motherboards. The following is summary table which includes a custom BIOS key, its fan utility, and recommended software (which I’ll get to later).
Fan Utilities and Recommended Software on Different Motherboard BIOSes
Tune Fans From Motherboard Application
Controlling the fan speed from your motherboard BIOS is always the best option and I suggest the same. But if you’re a regular user who doesn’t feel comfortable fiddling with settings from the firmware level, you can always use the manufacturer’s recommended apps.
Although I have listed the programs for the most popular motherboards (in the table above), they are not guaranteed to be compatible with all available models. Your manufacturer may have released a separate app specifically for your model, which may not work on others.
Therefore, I always recommend downloading the installation file directly from the manufacturer’s website instead of opting for a third party solution.
The specialty of the motherboard application is that you get access to most of the features available in your BIOS interface. For example, if you want to set the fan speed curve in MSI, MSI Center allows you to do it easily.
Apart from that, this application can even provide advanced features for better hardware monitoring and optimal adjustments. In fact, some even allow you to change the GPU fan speed, which is another discussion entirely.
Here’s a basic idea on how to control PC fan speed using motherboard software:
First of all, navigate to your manufacturer’s website, browse for your model, and go to the section Support . Find recommended software (should be under Drivers & Utility), download it, and finish the installation. Go to section dedicated fan control. This is different for every software and for some, you may even need to install special features (eg, User Scenarios in MSI Center). Now, you can choose speed control modes existing or customizing fan speed curve. Interestingly, some even allow you to set a duty cycle. For example, Gigabyte’s Control Center allows you to set fan Start and Stop temperatures. Final, save changes (if needed) and your fans will spin the way you want them to. customized input.
Setting Up Fan Control Using OEM Software
Tall Fan Tuning Demonstration Using AMD Software: Adrenaline Edition
If you are still looking for a software solution after not finding a compatible motherboard application for your model, you can try your fan manufacturer’s software.
Trusted cooling brands, such as Corsair, AMD, and Cooler Master all offer dedicated utilities that let you adjust speed, control fan RGB, and other advanced features.
But please note that the software is intended for one brand not compatible with other brands. So make sure you download the right one, directly from the official website.
Once you have installed the program, navigate to the dedicated fan section to change the fan speed. As with the previous method, you should find automatic and custom settings, including the option to set the Fan Speed Curve.
Here’s a list of some popular enthusiast OEMs with recommended software:
Try a Trusted Third Party Program
Demonstration: Using Fan Speed to control PC Fan speed
Currently, you can find several third-party applications that allow you to fine-tune the fan, to be sure high performance with minimal noise. They take advantage of clever features that are sometimes even better than the options available in your BIOS or the manufacturer’s recommended program.
These are some of my favorites–Fast Fan, Fan Control, Argus Monitor, and AIDA64. While there are a variety of tools available, here is a list of ten of the best fan controller software in detail.
Choosing a software solution (whether recommended by the motherboard, OEM, or a third party) does offer up-level customization of fan speeds. However, it also has some drawbacks.
Since this application requires special software drivers, the configuration applied will only work after the OS boots up. Therefore, if you are having problems getting started, it may not be the best choice.
Adjust Cooling Policy in Windows
Demonstration: Set the System cooling policy in Windows to On
Another possible way to gain automatic control over your fans is through the operating system’s cooling policies. On Windows, you can do this by selecting one of the two options–Active or Passive.
If you set the field to On, the button
However, if you want to reduce fan noise, we recommend setting the cooling policy to Passive. When you do, you will get a significant gain in system performance because it will slow down the processor first before increasing the fan speed.
While this isn’t a direct way to control the fans, it’s certainly a great option at the software level. If you haven’t changed before System Cooling Policythe option in your Control Panel is probably disabled by default.
So you need to enable it manually by changing the registry value first. Here’s a simple guide on how to set up System Cooling Policy in Windows.
Get Hardware Fan Controller
Hardware Fan Controller with Multiple Fan Headers
If your PC case has a built-in fan controller, you can adjust the speed directly via
Since you don’t have to bother opening BIOS or opening certain applications, this is certainly one of the quickest ways to control fan speed. Undoubtedly, it is very accurate and can help achieve optimal cooling performance as well as reduce noise level.
Some hardware controllers, as shown in the image above, allow you to connect multiple fans. All you have to do is insert the 3-pin/4-pin fans into their respective headers.
Then, connect the controller fan cable to the motherboard header. It’s best to use CHA_FAN, SYS_FAN, or even CPU_OPT (if they’re free). In this way, you can control the speed of each fan on your PC at once.
Even if your PC doesn’t have a dedicated fan speed controller, you can install one quite easily. However, if you don’t want to empty your pockets, you can stick with the previous method.
