The CPU is the most important component in a computer, and it generates a lot of heat when it’s running. To keep it from overheating, a fan is usually installed on top of the CPU. The fan works by drawing heat away from the CPU and pushing it out of the case. However, the fan can also generate noise, and it may not always be running at the optimal speed. In this guide, we’ll show you how to change the CPU fan speed without accessing the BIOS. By adjusting the fan speed, you can reduce noise and keep your computer cool.
How to Change CPU Fan Speed without BIOS?
Step 1: Download a Fan Control Program
To change the CPU fan speed without accessing the BIOS, you’ll need to download a fan control program. There are several programs available online, but we recommend using SpeedFan. SpeedFan is a free program that’s easy to use and offers a variety of customization options.
Step 2: Install and Launch SpeedFan
Once you’ve downloaded SpeedFan, install it on your computer and launch the program. SpeedFan will automatically detect your CPU fan and provide you with information about its current speed.
Step 3: Adjust the Fan Speed
To adjust the fan speed, click on the Configure button at the bottom of the SpeedFan window. This will open the Fan Control tab, where you can adjust the speed of your CPU fan. You can choose between automatic and manual fan control, and you can also adjust the fan speed by setting a custom fan curve.
Step 4: Save Your Settings
Once you’ve adjusted the fan speed, click on the Apply button to save your settings. You can also choose to have SpeedFan automatically start up when your computer boots.
Other methods to change the CPU fan speed without BIOS:
Method 1: Using a Fan Hub or Controller
A fan hub or controller is a hardware device that allows you to control the speed of your fans without accessing the BIOS. To use a fan hub or controller, you’ll need to install it inside your computer case and connect your fans to it. You can then adjust the fan speed using the controls on the hub or controller.
Method 2: Using the Manufacturer’s Software
Some computer manufacturers provide software that allows you to control the speed of your fans. For example, MSI provides the MSI Afterburner software, which can be used to adjust the fan speed on MSI motherboards. To use the software, you’ll need to download and install it on your computer.
Method 3: Using Third-Party Software
In addition to SpeedFan, there are several other third-party programs that can be used to adjust the fan speed on your computer. Some popular programs include:
- Open Hardware Monitor
- Argus Monitor
To use these programs, you’ll need to download and install them on your computer. Each program may have a slightly different interface, but they all offer similar features for adjusting the fan speed.
Method 4: Using the BIOS Emulator
If you’re unable to access the BIOS on your computer, you can use a BIOS emulator to make changes to your system settings. One popular BIOS emulator is the Unified Extensible Firmware Interface (UEFI) Shell. To use the UEFI Shell, you’ll need to download and install it on a USB drive and boot your computer from the drive. Once you’re in the UEFI Shell, you can make changes to your system settings, including the fan speed.
Tips for Changing CPU Fan Speed without BIOS
- Always monitor your CPU temperature when adjusting the fan speed. You don’t want to reduce the fan speed too much and risk overheating your CPU.
- Start with a small adjustment to the fan speed and monitor the CPU temperature. Gradually increase or decrease the fan speed until you find the optimal setting.
- If you’re not comfortable adjusting the fan speed manually, you can choose the automatic fan control option in SpeedFan.
Q: Is it safe to change the CPU fan speed without accessing the BIOS? A: Yes, it’s safe to change the CPU fan speed using a fan control program like SpeedFan. However, you should always monitor your CPU temperature to avoid overheating.
Q: Will changing the CPU fan speed affect my computer’s performance? A: No, changing the CPU fan speed will not affect your computer’s performance. However, it may affect the noise level and temperature inside your computer.
Q: What is the optimal CPU fan speed? A: The optimal CPU fan speed depends on several factors, including the type of CPU, the workload, and the ambient temperature. As a general rule, you should aim for a CPU temperature of around 60-70°C under load.
Changing the CPU fan speed without BIOS is a simple process that can help you reduce noise and keep your computer cool. By following the steps outlined in this guide, you can easily adjust the fan speed using a program like SpeedFan. Just remember to monitor your CPU temperature and start with small adjustments until you find the optimal setting. With a little bit of tweaking, you can enjoy a quieter and cooler computer.
