how to change cpu fan speed without bios

Are you looking for how to increase or decrease CPU Fan Speed Without Bios? You are in the right place. We will give two different working methods on how to change cpu fan speed with bios.

The CPU cooling fan is an essential component that guarantees the efficient operation of your PC. The ability to control the CPU fan will aid in keeping your system and GPU temperature cool and calm.

When you play games or utilize demanding software, you may find that your computer overheats.

These are some of the issues that might develop when you can not control your CPU fan’s speed.

Fortunately, you can ensure that your computer is working smoothly by increasing the speed of your computer’s fans.

The majority of the time, users desire to change the speed of their CPU fan in the BIOS. This is the most suggested strategy; however, it does not always work.

If you’re having difficulties reducing or boosting the CPU fan settings, these post could be what you’re looking for. Here’s how to change the CPU fan speed without BIOS.

1. Utilize Fan Control Software To Change CPU Fan Without Bios

Although you may manually adjust the speed of your computer fans, it is preferable to use the automated option. In this instance, fan control must be accomplished via the use of software.

An automated fan controller software will monitor the CPU temperature and, if necessary, enable you to adjust the fan speed on your PC.

When a CPU becomes too hot, the PC fan controller software will slowly increase the fan speed until the system returns to normal.

You can control the speed of the fans using a variety of applications. Making the appropriate decision, on the other hand, should be your first focus.

This will be advantageous if the software you select is compatible with the operating system, including Windows 10.

If you’re open to utilizing PC fan controller software, SpeedFan is a fantastic place to start.

What exactly is SpeedFan?

Speed fan is a free software for Microsoft Windows that monitors fan speed and CPU component temperatures.

It allows you to control the fan speed manually, and it also has an automated fan speed function that monitors the temperature of the components and controls the speed appropriately.

Take note: SpeedFan is one of the most popular fan control software; its appearance may seem obsolete to you, but it is free software written by an individual. For new users, setting up the software might be difficult; thus, we urge that you carefully follow the procedures below:

Step 1: Download and install SpeedFan: Download the SpeedFan installer from this page. Install it and then open it after download. When you launch the software, it will scan all of the buses on your motherboard.

Step 2: Set up fan control: Please do not attempt to change the fan speed using the PWM controls as soon as you open the software since you must first configure it.

  • When you click “Configure,” a new window will open.
  • Now, click “Advanced.”
  • After selecting “Advanced,” select the “Chip” option from the drop-down menu.
  • Look for your PWMs in the menu (if you don’t know where your PWMs are, try clicking on all the chip drop-down choices).
  • Select the PWMs you wish to control after you’ve located them.
  • After choosing the PMW, you will see a “Set to” selection from which you must select “Manual” or “Software-controlled.” (By doing so, Speedfan will be able to control your fans.) To preserve the settings, make sure you click on “Remember it.”
  • You may now return to the main window and view PWM1, PWM2, PWM3, PWM4, and PWM5. Select the PWM you modify, and you may directly change fan speed by typing or using toggle buttons.

Step 3: Configure the automated fan control: We discussed how to control fan speed in step 2. However, it is a manual process. You may also enable automatic fan control, which means that if your CPU begins to overheat, the Speedfan will automatically raise the speed, and when it cools, it will decrease the rate.

You may enable automatic fan control by selecting “Configure,” then “Fan control,” and finally “Advanced Fan Control.”

2. Make Use of External Fan Controllers

Have you exhausted all possibilities, and are you still unsure how to change CPU fan speed without BIOS?

It would be best if you thought about trying an external fan control. Having a controller for your fans enables you to monitor your computer’s temperature and manually adjust the speed of your fans.

As long as you have suitable PC fan controllers, you will be able to assist your system in attaining the ideal balance of calm and relaxation.

Before you buy a PC fan controller, consider its aesthetics, pin compatibility, controls, and channels.

Several external fan controllers are on the market, but none outperform the Corsair Commander Pro and Noctua in terms of performance, efficiency, and usefulness.

Frequently Asked Questions

What causes computer fans to run continuously?

If your CPU fans are constantly spinning at full speed, it might be due to a faulty heat sink or temperature sensor. It might also be due to CPU difficulties. However, the most typical source of this problem is a defective temperature sensor.

What causes a computer fan to be noisy?

Typically, filthy fans cause computer fans to run at high speeds. Dust may harm fan bearings and cause them to make loud noises; thus, it is best to clean your computer fans using compressed air cans, an electronic vacuum, or a moist cloth.

What causes computer fans to speed faster?

High CPU use by demanding games and video editing software may cause CPU temperature to rise. Therefore, computer fans begin to spin at high RPMs for active cooling.

What is an appropriate CPU fan speed?

When you are casually using your PC, you may maintain the fan speed between 50-70% of RPM. However, if you are gaming or performing intensive 3D work or video editing, your CPU might overheat; therefore, you should set on all of the fans if the temperature rises beyond 60 – 70° Celcius.
