What is Sys Fan on Motherboard

Your computer’s motherboard contains many different components that work together to keep your machine running. One of these components is the sys fan, which helps to cool down your system and prevent overheating. The sys fan is located on the back of the motherboard and is usually a small, round object.

If you notice that your sys fan is not working properly, it is important to take action right away in order to avoid any damage to your computer. There are a few things that you can do in order to troubleshoot the issue and get your sys fan working again.

A system fan, or CPU fan, is a type of cooling fan that helps cool down your computer’s components. It is typically located on the back of the CPU and blows hot air away from the processor. System fans are important for keeping your computer running smoothly and preventing overheating.

Sys Fan 1 Or 2

Whether you’re a PC gamer or just a casual user, you’ve probably noticed that there are two different types of computer fans: system fans and case fans. But what’s the difference between them? System fans, also known as CPU coolers, are designed to keep your processor cool.

They usually sit on top of the CPU and have heatpipes that help dissipate heat away from the processor. Case fans, on the other hand, are designed to keep your entire case cool. They typically sit in the front or back of the case and help circulate air throughout the case.

So which type of fan do you need? It depends on how you use your PC. If you’re a heavy PC user who does a lot of gaming or video editing, then you’ll likely need both system and case fans to keep your components cool.

However, if you’re a casual user who only uses their PC for browsing the web or doing light work, then a single system fan should be sufficient.

Is Sys Fan Necessary?

If you’re wondering whether or not you need a SYS fan, the answer is probably yes. The main purpose of a system fan is to cool down your CPU and prevent it from overheating. Without a system fan, your CPU could overheat and potentially damage your computer.

There are a few things to keep in mind when choosing a SYS fan. First, make sure that the fan is compatible with your motherboard. Second, consider the airflow requirements of your case.

If you have a lot of other components in your case that generate heat, you’ll need a more powerful SYS fan to ensure adequate cooling. Finally, think about noise levels. Some fans can be quite loud, so if you’re looking for a quiet computer, make sure to choose a quieter SYS fan.

Is There a Difference between Cpu Fan And Sys Fan?

There is a difference between CPU fan and SYS fan. A CPU fan helps to cool the central processing unit of a computer, while a SYS fan helps to cool other system components. In most cases, it is recommended to have both types of fans installed in order to keep the computer running smoothly and prevent overheating.

What is the Use of System Fan?

The system fan is a very important component in any computer. Its main purpose is to cool down the components inside the computer case. By circulating the air inside the case, it helps to keep the temperature of the components at a safe level.

Without a system fan, the components would overheat and eventually fail. There are different types of system fans that can be used in a computer case. The most common type is an exhaust fan, which helps to remove hot air from inside the case.

Other types of system fans include intake fans, which help to bring cool air into the case; and spot cooling fans, which are used to cool specific areas or components inside the case. When choosing a system fan for your computer, it is important to consider its size, airflow and noise level. The size of the fan will determine how much air it can move; airflow is measured in cubic feet per minute (CFM); and noise level is measured in decibels (dB).

A higher CFM rating means that more air will be moved by the fan; however, this also usually results in a higher noise level. It is also important to make sure that your chosen system fan will fit into your computer case. Most cases have mounting points for one or more fans on either side of the front panel or on top of the power supply unit (PSU).

Once you have determined where you want to mount your fan(s), check their dimensions against those of your case to ensure compatibility.

Can I Plug My Cpu Fan into Sys Fan?

Most computer cases have multiple fan mounting points. The most common are CPU and system fans. But what happens if you want to move a fan from one mount to another?

For example, can you put a CPU fan in the system fan mount? The answer is maybe. It depends on the size of the fan and the mounting point.

Some CPU fans are the same size as system fans, so they will fit in the mount. Others are not, so they won’t fit. And even if the fan does fit in the mount, it might not line up with all the screw holes.

So you might be able to get it in, but then not be able to secure it properly. If you do decide to try and put a CPU fan in a system fan mount, make sure you use screws that are short enough that they don’t protrude into any delicate components on your motherboard. You don’t want to accidentally short something out!


The sys fan on a motherboard is responsible for cooling the CPU. It is typically located near the CPU socket and is usually made up of a metal or plastic casing with a fan inside. The sys fan blows air over the CPU to keep it cool.

If the sys fan fails, the CPU can overheat and damage the motherboard.
