How to Connect Extra Fans to Motherboard

A motherboard is a component that provides electrical connections for an electronic circuit. Connecting a fan to a motherboard is easy, but what about connecting extra fans? This article explains how you can do just that!

Connecting Fans to Motherboard

A motherboard is a central component in a computer that connects all the other components, including the CPU, RAM, and GPU.

When it comes to cooling, a good motherboard will come with multiple fan headers that can be used to attach extra fans to cool down its components. This guide will show you how to connect extra fans to your motherboard’s fan headers.

First, ensure you have the correct motherboard and fan header connectors. Most motherboards have 4 or 5 fan headers (although some may have as many as 7), and each header can support up to 3 fans. Make sure you identify which fan header(s) your motherboard has before proceeding.

To connect an extra fan to your motherboard’s fan header(s), unplug the existing fan from the connector on the motherboard.

Then, plug one of the female ends of the new fan into the connector on the motherboard, and plug the other female end of the new fan into one of the male ends of your other fans. Finally, plug in your power supply and start your computer up.

The Benefits of Using More Fans

  1. Adding more fans to your computer can help ensure that it stays cooler and runs more smoothly.
  2. By adding more fans, you can also improve the airflow within your computer, reducing noise levels and improving performance.
  3. Additionally, by adding fans to your computer, you can help circulate air around the components within your system, helping to keep them cool and preventing them from overheating.

Connecting Extra Fans with a Cable

A cable can connect extra fans to a motherboard’s fan header. This allows the motherboard to control the fans and avoid running them continuously in succession. To connect an extra fan: 

  1. Remove the extra fan from its box and screw it onto the motherboard’s fan header using the included screws.
  2. Plug in the power supply to the motherboard and plug in the fan cable to one of the fans.
  3. Repeat steps 1-2 for each additional fan used.

Types of Motherboard Fans

There are various motherboard fans, so it can be hard to know which one to buy. Here’s a guide to help you choose the right fan for your motherboard.

CPU Fan: If you have a CPU with a heat sink, you’ll need a fan to blow air over the heat sink and onto the CPU. Most motherboards come with one or more small fans that work well for this purpose.

System Fan: A system fan is usually much larger than a CPU fan and is used to cool down the entire computer system. Most motherboards include at least one system fan, but you may also need to buy an extra one.

Storage Fan: Storage fans pull hot air out of your computer case and into the open air. They’re not as important as other fans because most computers don’t have many components that need cooling, but they’re still useful if you have a high-powered graphics card or large hard drive.

GPU Fan: GPUs (graphics processing units) are powerful chips that often require a dedicated cooling system. You’ll need an extra GPU fan if your computer has one.

Ways to Connect Fans to the Motherboard

Depending on the fan controller and your setup, there are many ways to connect extra fans to the motherboard. Some fans can be directly connected to the motherboard, while others require an external controller.

If you want to connect a fan directly to the motherboard, you’ll need a fan connector or adapter. There are many different types of connectors and adapters, so it’s best to find one that fits your specific setup.

Some fans require an external controller to work properly. These controllers attach to the motherboard via USB or other ports and allow you to control all the fans in your system from one place.

There are a few popular fan controllers, including the Noctua NF-A14 & NF-A15 PWM Fan Controllers and the Fractal Design Node 202 AC Support Unit.

Threads for Connecting a Fan to a Motherboard

You can connect extra fans to your motherboard if you want to cool down your system or increase airflow. Adding more fans will not only help improve the airflow within your computer, but it can also help reduce noise levels.

There are a few different ways to connect extra fans to your motherboard. You can use threaded inserts, fan headers, or 4-pin Molex connectors. Each method has its advantages and disadvantages.

Threaded Inserts: 

The simplest way to add an extra fan is by using threaded inserts. These inserts fit into grooves on the motherboard and allow you to screw in an extra fan. This method is easy to install and use, but it requires that you have a matching thread on the fan and the motherboard. 

Fan Headers: 

Another option is fan headers. These headers are similar to threaded inserts but have less flexibility and are designed for thinner fans. Fan headers are more expensive than threaded inserts, but they offer more options for connecting fans. 

4-Pin Molex Connectors: 

Finally, you can connect extra fans directly to your motherboard using 4-pin Molex connectors. This approach is generally easier than using threaded inserts or fan headers, but it requires that you have a dedicated 4-pin Molex connector available on your motherboard.

Tips for Successfully Using Extra Fans

Using extra fans can make a big difference when it comes to cooling your laptop. Here are some tips for successfully connecting extra fans to your motherboard:

  1. Clean the ports on your motherboard: Dirty ports can cause problems when connecting an extra fan. Make sure to clean any dust or residue from the ports using a small brush or q-tip.
  2. Check the orientation of the fan: The fan must be facing the correct direction when connecting it to the board. The arrow on the fan should point toward the CPU socket. If it doesn’t, you may need to turn it around so that it does.
  3. Use a compatible connector: Some motherboards have special connectors for extra fans. Others require that you use standard 3-pin connectors, which most fans will fit into easily. Just be sure to check before plugging in your fan!
  4. Connect one end of the cable to the fan and the other end to a power source: This is usually easiest done by plugging in one end of the cable into a power outlet and then plugging in the other end of the cable into either your laptop’s main power switch or port (if available).

Frequently Asked Questions

What are the benefits of adding extra fans to a motherboard?

Adding extra fans to a motherboard can benefit in several ways. Extra fans can help improve cooling performance, increase air circulation and reduce noise levels. Additionally, adding extra fans can assist the overclocking process by providing additional airflow and heat dissipation. Ultimately, users can gain increased system stability and overall performance by adding extra fans to a motherboard. 

How do I know if my motherboard supports extra fans?

Most motherboards include a specification sheet that lists the maximum number of fans the board can support. Additionally, some motherboard manufacturers include information on fan compatibility within the user manual. If your motherboard does not include a fan specification or compatibility information, or if you are unsure whether your motherboard supports extra fans, please contact the manufacturer for assistance.

Are extra fans compatible with my case?

Generally speaking, extra fans are compatible with most cases. However, it is important to verify the compatibility of your case before purchasing additional fans. Some cases include specific fan connectors that may not be compatible with extra fans. Additionally, certain cases may require users to remove the motherboard tray to install additional fans. If you are uncertain whether your case is compatible with extra fans, please contact the manufacturer for assistance.

Conclusion

If you want more fans for your motherboard, connecting extra fans to it can be great. Adding an additional fan will increase the airflow and cooling capacity of your motherboard, which should help keep it running at its best.
