How to change CPU fan speed without bios? Today, I will answer this question in detail.

If your computer is heating up, you want to speed up your fan to cool it down. Overheating is not the only reason you should control fan speed. If your fans are operating at maximum throttle, it is possible to reduce the speed using one of the strategies described in this article.

Although BIOS allows you to control the fan speed, it is not always possible. If you’re facing a similar problem, there are multiple ways to control fans without BIOS.

How To Change CPU Fan Speed Without BIOS

1. Download Fan Control Software

There are many fan control virtual products, including Corsair Link and NoteBook FanControl, Argus Monitor, SpeedFan, e.t.c. Each one is acceptable. However, this article will explain how SpeedFan can be set up to control fan speed.

How do you use a SpeedFan?

SpeedFan is a Microsoft Windows software that monitors fan speed and temperature of the CPU segments. You can control fan speed by moving your mouse. It also has a program that displays fan speed and tracks temperature.

Note SpeedFan is the most popular fan control programming. Although it may seem outdated to you, its a free program written by someone. It can be confusing for novices to set up the product. We recommend that you carefully follow the instructions below.

Download SpeedFan

The SpeedFan installer is available for download. Once it is downloaded, open it. After opening the application it will filter all the transports on your motherboard.

SpeedFan Configuration

Do not open the product and try to adjust the fan speed using the PWM controls.

  • Click on “Design” to open a new window
  • Click on “Cutting Edge”
  • After tapping on “Cutting edge”, you will need to tap the “Chip” dropdown menu.
  • Search PWMs in the menu. If you aren’t sure where they are, take a look at the dropdowns. 
  • Once you have identified your PWMs, you can select the ones that you want to manage
  • After selecting the PMW, you will see a dropdown titled “Set to”. You need to choose between “Manual” and “Programming controlled.” This will allow Speedfan to control your fans. To save your settings, make sure to click on “Recall It”.
  • You can now return to the main window. Here you will see PWM1,PWM2,PWM3,PWM4, and PWM5. You can now select the PWM that you have arranged and you can use switch catches or physically type to adjust the fan speed.

Shift It to Auto

We have already explained how to control fan speed in sync 2. However, this is manual. Speedfan can also be programmed to turn off fan speed when your CPU starts overheating. When it cools down, Speedfan will slow down.

To set up fan control programs, tap on “Arrange”, and then click on “Fan Control” to check the progress.

2. External Fans

You have exhausted all the options and are still trying to figure out how to slow down your CPU fan speed.

You should seriously consider an External Fan Controller. A regulator for your fans allows you to monitor the temperature of your computer and change the speed of the fans.

You will help your system achieve the perfect balance of cool and peaceful, no matter how long you are.

Consider the feel, pin backing, controls, as well as channels, before you start looking for a PC fan controller.

3. PC Fan Controller

A fan regulator can be a good investment if you require more power to control your fan and other parts of your frame. The H-series H from NZXT, have an embedded connection box that gives you programming control over your CPU fan in the same way Speedfan but more naturally. This box also supports RGB lighting, fan profiles and fan bends.

You can get more control with independent fan regulators. A few, such as the ThermaltakeCorsair iCUE, give you touchscreen control for the fans in your framework. Others have dials and handles that you can use to manage them.

These directions will be important as the arrangement and executive details are relevant to your individual plans.

Check your PC Hardware

You will need to access your computer and verify a few things before you purchase any fan regulator. First, determine how many fans your computer has. This will allow you to choose a fan regulator that protects all of them. Also, you will need to disconnect all fans from your motherboard in order to determine if they use a 2, 3, 4, or 5 pin connector. When you purchase a fan regulator, you will need to know what type of connector your fans use.

Make sure you have something to ground yourself when working with your computer. You can avoid static emissions that could cause damage to your computer. It is possible that you will need to purchase a few static wrist bands to use while you work on your computer. A single static release can cause the entire PC to crash.

Purchase a fan regulator

A fan regulator can be purchased online or at a local PC shop. You should ensure that the fan regulator you purchase can hold all the fans on your computer and has the correct pin connectors. Fan regulators will need to be installed in the drive bay of your tower.

If your fans use 2-pin or 3-pin connectors on your PC, you may be able to purchase new fans with either 3 or 4 pin connectors. 2-pin connectors provide an electrical flow to your fan. 3-pin connectors allow the fan to control its speed. 4-pin connectors allow for speed control.
