How To Adjust The CPU Fan Speed?

Sometimes you must have to adjust the CPU fan speed to avoid the issues of overheating as well as overclocking and also any kind of damage. Manually adjusting the CPU fan speed is also a very important step in overheating and overclocking a CPU. As you can hear the CPU fan noises when you reboot the PC and it can be heard as the startup process completes.

The purpose to install the fans on your CPU is to blow off the heat that may generate when a process is going through. Sometimes you feel that your pc is getting too hot but after a while, it becomes cool down; it’s just because of these fans. But sometimes these fans cannot be able to control the overheating.

 One of the common reasons a PC starts overheating is that the internal fans do not operate at the required speeds. This is because the automatic fan controller is not functioning properly. But luckily, you can easily adjust the CPU fan speeds manually using some easy and different methods.

So if you want to adjust the CPU fan speed then you need to know how to adjust the CPU fan speed. So keep reading this detailed guide so that you can learn the easiest way to adjust the fan speed. This guide covers all the basic facts to learn how to manually adjust the CPU fan as well as any other case fans.

Why is it important to monitor CPU Fan Speed in Windows?

Basically, it’s too important because The CPU fans are pretty straightforward. They always check the PC’s temperature and get turned on and off accordingly to the situation. as we all know that there are air vents in all PCs that allow the heat to escape. If you notice that, these CPU fans are running constantly, that means, your system is overloading.

Then, it is very important to maintain a balance or adjust the CPU fan speed to keep your PC’s temperature absolutely normal. If you don’t do this, you may face some kind of issues and damage.

Fan types

Before adjusting the CPU fan speed, you must have an idea about the type of fans you have. CPU fans can easily adjust, but other fans in the PC are not so flexible. The simple way to identify the fan is to check the connector. You will see three types of fans Molex, DC, and PWM.

1. Molex fans

Molex fans are designed as flat four-pin connectors for direct connection to the power supply. These fans are located at bypass the motherboard, so it is impossible to adjust manually.

2. PWM and DC fans

You can easily adjust the two remaining fan types, DC and PWM.  A PWM fan is small, four-pinned, and rectangular in shape, and it can be easily plugged into the motherboard.  DC fans are almost identical to PWM fans because they have a three-pin connector instead of a four-pin. You can adjust PWM fans to run in DC mode, but it’s not recommended.

How to adjust The CPU Fan Speed?
