The main window will bring the RPM of the fans and will give you all the information about the temperatures of the motherboard chip, processor, hard disk, and so on.

You can also use system monitoring tools such as Core Temp and HWMonitor to monitor and adjust the fan speed.

Generally, these tools will allow you to set the fan speed to a fixed speed or to a custom speed profile that you define.

Depending on the specific hardware and software you use, you may also be able to set the fan speed to automatic, allowing it to be adjusted based on the temperature of your system.

Step 2: Doing things with some fan controls

When you are done with all the introductions with temperatures you can move forward with step-2.

You should keep in mind that the SpeedFan software is not that easy to deal with. It’s a little bit complicated. Allowing the automatic fan speed process won’t be enough for meeting all your needs.

This software is available for free from many different sources, and can be used to adjust the speed of the fan to match the temperature of the CPU.

The software can also be used to set the fan speed to a specific level, or to automatically adjust it based on the temperature of the CPU.

It can also be set to alert you when the temperature of the CPU reaches a certain level, allowing you to adjust the fan speed accordingly.

Step 3: Setting automatic fan control

Go to the “Speeds” tab after being done with clicking the configure button and setting the RPM to both maximum and minimum for your fans.

Then go to the fan control tab and set the temperature according to your choice. This step will also help you to see if there is any wrong with your whole process.

However, finally, go to the Temperatures tab to set up when to speed up the fan and when to slow down and also set the Desired and Warning temperatures.

So that you can be noticed if everything is okay or not. Now that you are done with changing the CPU fan speed, you won’t face any difficulties.

Fan speed settings can be adjusted manually, or the application can use a pre-determined profile such as silent or performance.

Users can also customize the profile to their own desired settings. Using a third-party application to adjust fan speed settings is an easy and convenient way to control the fan speed without having to access the BIOS.
