How To Connect Extra Fans To The Motherboard? [Guide 2023]

Do you have extra fans for your computer system and want to know how to connect extra fans to the motherboard? It is standard for people to have other fans for their computer systems. This happens when you need additional cooling for your system, or it is an air cooler.

Various types of fans are available in the market, and there are many types of fans that different companies manufacture. Most of the fans are connected to the motherboard using some connectors, and I will explain this concept if you are new to it in this article.

The fans are connected to the motherboard using two types of connectors. There is a fan header connector on the motherboard itself, and fans are related to this fan header via a small box. The second type of connector is a fan cable. The fan cables are connected to the fan and are provided with power.

Things to Know Before Installing PC Fans

PC fans are essential parts of your computer. They keep your motherboard cool, and they help to dissipate heat. There are many different types of fans, but each is designed for a specific purpose. So, it’s essential to understand the differences between them.

There are two main categories of fans. These are the CPU cooler fans and the extra motherboard fans. The former is used to cool the processor, while the latter is used to cool the motherboard.

CPU Cooler Fans

The most common type of fan is the CPU cooler fan. This is a small, round, white fan that sits on top of your processor. It is also known as a heatsink fan. It helps to keep the temperature of the processor by blowing air across the surface of the chip. It can be found inside the case of the computer or outside in the open.

Motherboard Extra Fans

The other kind of fan is the extra motherboard fan. This additional fan is placed near the power supply, which keeps the entire system running smoothly and prevents overheating. If you want to know more about these kinds of fans, then read on.

How to Connect Extra Fans to PC?

It is evident that when you use your computer, you need to connect some extra fans to the motherboard because the motherboard has no fans built into it. Nowadays, it is the trend that we don’t buy any other fans; instead, we purchase them in online stores and connect them to the motherboard.

This way of connecting fans will increase your motherboard’s performance and boost your computer’s performance.

Here are the steps that will help you to connect extra fans to the motherboard.

Step 1: First, you need to get a new fan adapter. The first step is to open the back of your motherboard and find a connector to connect the fans.

Step 2: You need to cut the connectors connected to the fans. Cut the connectors from the middle and solder the adapters to the back of the motherboard.

Step 3: After completing the above steps, you need to put a screwdriver in the middle of the fan and put the fans in the adapters.

Step 4: Once done with this step, you need to screw the fan to the adapter.

Step 5: Once the fan is connected, you need to turn it on, and it will start working correctly.

How to fix the connection of the extra fans to the motherboard?

The motherboard has several fans that are used to cool down the components of the system. The motherboard’s chipset usually controls these fans. These fans also manage the airflow inside the case; they can be found outside the issue and are called extra fans. These additional fans are mainly used for increasing the airflow of the system.

You will also notice that the extra fans are connected to the power supply, and the fans are directly connected to the motherboard, but this isn’t the only way to connect the different fans to the motherboard. There is a separate connector attached to the motherboard, and that is where you will have a lot of problems.


  • You will face a very low or no sound when the system is under a heavy load
  • The system will slow down and will consume more energy
  • There is a risk of damaging the motherboard.


If you are experiencing these problems, you can try fixing them using the following solution.

Fixing the extra fan connectors is a straightforward task. All you need to do is remove the fan from the power supply, and then you will need to remove the connector connected to the power supply. After that, you must click the new fan on the motherboard. After that, you will need to reconnect the fan to the power supply and then place the fan back in its position.

Frequently Asked Questions

How many fans can I connect to my motherboard?

You can connect as many fans to your motherboard as you want, as long as you have the appropriate power connectors. However, the motherboard will most likely reject fan connectors with different wattage.

Can you plug fans directly into the motherboard?

Yes, you can plug fans directly into the motherboard to cool off the graphics card or processor. However, this is a risky practice, as it can cause damage to your motherboard. Hence, you should only use this technique if you have a fully-tested motherboard and the fan manufacturer has confirmed that it works with your specific motherboard.

How do I connect extra fans to my power supply?

A fan fuse or a fan circuit breaker can connect extra fans to the power supply. But if you want to go the DIY route, you can connect them directly to the power supply. The only thing you need to do is to make sure that your fans don’t draw too much power.

How do I connect multiple RGB fans to my motherboard?

RGB fans usually have a dedicated PWM channel and a power connector, and you can directly connect them to a motherboard without a separate power adapter. For instance, the BASICS RGB Fan comes with a power connector that you can now plug into the motherboard, and it uses a PWM channel to control the fan’s speed.

Can you daisy chain PC fans?

Yes, you can daisy chain PC fans. There are certain advantages to doing so, but you’ll have to determine which ones apply to your situation. If you’re building a data center with many servers, you can maximize the number of fans you can use by daisy-chaining them together.
