What is sys fan on motherboard? You will notice the sys fan or system fan either in the front or side of the radiator attached to the case.
Generally, different types of fans are installed on a computer. Suppose you want to maintain the unit for an extended period of time. In that case, you should know its functions, differences, and how they are actually affected.
So, keep on reading to know more about the sys fan of your computer.
What Is Sys Fan On Motherboard?
Motherboard, mobo, or baseboard, whatever you call it, is the biggest board of the computer. It has directions printed all over the body for allocation of power and communication between all the computer components. Usually, Sys fan 1 is the header where you connect the sys fan wires.
Basically, sys fans or system fans change the hot air inside the computer case with cooler air from outside.
How Sys Fan Functions
According to the law of thermodynamics, heat moves from the hotter object to the cooler object.
As the computer components get hot during operation, some of the heat gets transferred to the air. In this process, the hardware loses heat, and the air becomes hotter. But once the temperature is equal between the air and the components; no heat can be transferred, leading to the damage of expensive parts.
At that time, the sys fan inside the case starts working. It replaces the hot air with fresh and cooler air. So, the hardware gets to transfer its heat into the air again.
The sys fans 1 to 4 on the motherboard are reserved for the chassis fans. There are no limits on how many fans you can add to the fan headers. It solely depends on the power they draw from the headers. At any cost, the total power drawn must not be more than the power capacity of the headers.
Why Sys Fan Is Necessary
Like any other electronic gadget, Computers are exposed to the danger of overheating. You may ask how. When you run the computer for a longer period or engage it in harder operations like gaming or video editing, it tends to get heated up. And when a major part of the computer is overheated, it can lead to issues of damage, immediate shutdown, and even fire. So, what’s the remedy?
The answer is fans. Though we will be highlighting the benefits of sys fans in this article, every other fan does more or less the same work. The heat won’t dissipate without a fan that transports the hot air out of the computer case, the heat won’t dissipate. And the computer has a pre-set temperature. Once the heat reaches that limit, it won’t run anymore. That means you need a sys fan for the smooth or uninterrupted operation of your pc.
Sys Fan VS CPU Fan
Although both the fans do almost similar tasks, they differ in many aspects. Let’s take a look.
- The main difference between a sys fan and a CPU fan is their location. While a sys fan is attached to the side or front of the case, a CPU fan is installed within a heatsink. A heatsink can be both active and passive.
- While a sys fan belongs to the headers named Sys fan 1, sys fan 2, and sys fan 3, the CPU fan has to be plugged into the CPU header.
- You only get one CPU fan set inside the central processing unit. In contrast, the number of case fans can be increased or decreased according to your demands. You may want to add more than 3 sys fans for better cooling management for a gaming computer.
Pump Fan VS Sys Fan
Now let’s jump into the basic differences between Pump fan vs sys fan.
- You may ask – “what is a pump fan?”While the sys fans move air, pump fans work with liquid. Pump fans are mostly used for a liquid cooling system.
- Sys fans produce a medium amount of noise while running, which can be annoying to some people. In contrast, the pump fans operate quietly without any irritating sound.
- Again, sys fan headers are mentioned on the motherboard as sys fan headers 1-4. Pump fan 1 is the fan header for your pump fan.
Many people plug the pump fan connectors into the CPU header to use it as a Pump fan header. But that can cause an error or shut down notification to show up once you post it.

Frequently Asked Questions (FAQs)
Is sys fan necessary?
Ys, it is. Sys fans or chassis fans are located beside or inside the case of the computer. What they do is let cool air in and move the hot air out. Computers produce a lot of heat while operating, and if that heat is not reduced by means of a sys fan, it can damage the whole pc.
How Can I Control A Sys Fan?
Sys fans are connected to the motherboard, which means they are controllable. You can reboot your pc and click on the BIOS set up. Then look for the system configuration setting. There you get to adjust the fans easily.
What Is The Number Of Fan A Sys Fan Have?
It is not the number of fans we should talk about. Rather the amount of current each fan draws out is what determines the number. If one system fan header can supply 1A, then you can plug 4 fans into it, each drawing 0.25A. The less power your fans require, the more you can install.
Conclusion
System fans, as known as CHA fans, are the only way your expensive computer parts can continue working.
Though the CPU of a computer stays hungry for an individual“CPU fan,” smart users never ignore the potential of a sys fan. And if you are a pro-level gamer or engage in stuff that puts a heavy load on the unit, you can’t get away without sufficient sys fans.
Without a doubt, it complements the cooling system in the way it requires! Hopefully,now you know well what is Sys Fan on Motherboard.
