Most computer cases come with one or more pre-installed case fans. In many cases, these are sufficient to keep your components cool. However, if you’re looking to overclock your CPU or GPU, or if you live in a particularly warm climate, you may need to install additional case fans.
We know, that connecting one fan is simple, but connecting multiple fans can cast problems for most users. Therefore, in this article, we’ll discuss the importance of case fans, types of fans, and how to connect multiple case fans.

What is Fan Header?
Basically, fan headers are the terminals on the motherboard into which PC cooling fans are hooked. And motherboard uses these headers to monitor & control PC fans.
Most motherboards have at least one fan header, and some have multiple headers for connecting multiple fans. The fan header is typically located near the CPU socket, and the fan is typically mounted on the CPU cooler.
The fan header uses a 4-pin connector, and the pinout is typically labeled on the motherboard. The fan header can also be used to connect other types of 4-pin devices, such as LED strips.
Types of Fan Headers:
On your motherboard, you will find three types of fan headers which are as follow:
- CPU Fan Header: This fan header is used to connect the CPU to the fan.
- System Fan Header: This fan header is used to connect PC fans.
- Power Fan Header: This fan header is used to monitor the power supply unit’s fan.
Note: The only fan header that is suitable for PC case fans is the system fan header.
Importance of PC Case Fans:
PC case fans ensure that the computer system is receiving optimal cooling, but this can be challenging in some cases. No doubt, you could go for maximum power by lifting as many cooling fans into & onto the PC casing.
For adequate cooling, your computer system must have enough PC fans to push & draw air into and out of the PC case.
How To Connect Multiple Case Fans
Below, we have discussed one of the most common ways to add multiple fans to your PC case.
Method 1: PC Fan Hub
A PC fan hub is the most common and popular method to connect multiple case fans to the motherboard without worrying about power usage.
One of the best benefits of PC fan hubs is that they aren’t restricted to the 1 Ampere rating of the motherboard fan headers. They also get power directly from the supply unit through the 15-pin SATA power cords.
So, you can add high-powered case fans without worrying about overloading the motherboard fan header.
A PC fan hub is easy to set up, it requires one SATA power connection from the PSU and one 3-pin or 4-pin connection from the motherboard header to the fan hub.
The female end of the fan hub connects to the motherboard, which then branches into multiple male headers to which you can attach fans. Usually, a fan hub can connect up to 10 fans.
Method 2: Use a Y-Splitter
Using a fan header splitter is the cheapest & easiest way method to connect multiple case fans. Although, the number of case fans that you want to connect with is determined by the amperage of the fans.
Setting up a Y-splitter is pretty easy. The female end of the splitter is plugged into the motherboard’s fan header. While the case fans will be attached to the splitter’s male end. That’s it!
Frequently Asked Questions
What are the benefits of connecting multiple case fans?
The benefits of connecting multiple case fans are numerous. For starters, it allows for better airflow throughout the case which can help keep components cooler and running at peak performance.
Additionally, it can also help to reduce overall noise levels as each fan will not have to work as hard to move air.
What are some things to keep in mind when connecting multiple case fans?
When connecting multiple case fans, it is important to make sure that they are all the same size. Additionally, it is also important to ensure that the fans are compatible with each other and with the motherboard.
Finally, it is also important to have a good understanding of how airflow works in order to ensure that the fans are placed in the most effective positions.
If you want to keep your computer cool, you need to use case fans. However, you might be wondering how to connect multiple case fans. In this article, we’ve discussed provided step-by-step instructions on how to properly install and connect your case fans.
