Where To Plug Fan Controller Into Motherboard?

If you are planning to connect the fans to your motherboard, you will at first have to identify the motherboard pin connector and only then you will be able to do the rest of the work at ease. Remember that if you are using RGB fans, make sure that all the colours are in sync! In case you fail to do it right, you will end up causing a lot of damage to your motherboard system as a whole. In case you are thinking this job is too tedious or tricky, there’s nothing to worry much! Note that it is only because you ought to have the exact instructions in order to get things in place, and the rest will automatically settle down in just no time.

How Will You Connect The Fans To Your Motherboard?

In order to ensure that all the things are going right, you will first have to choose the right kind of fans for your motherboard. Once you have got them appropriately, your next task would be to ensure that you are making all the connections precisely as per their specifications.

Here are a few significant things that you might need to check:

Although most of the motherboards that we tend to use these days come with pre-installed fans, you need to be sure about their quality too. While the front fan would usually bring in cold air for you, the rear one will enable you to get the hot air outside. Adding any extra fan will only make sense when you are a gamer or are planning to do some sort of high-end activities with your PC.

Finding a fan that will be just right for your device will certainly call you for a good amount of research, and thus, you must always have clarity about their specs and the pins that would match the same! Most of the motherboards that are readily available in the market as of now come with a provision of supporting 4-6 fans. Besides, the modern motherboards will allow you to connect both the 3-pin and 4-pin fans to the 4-pin headers.

Check the compatibility of your fans:

The two major connection options available to you are:

  1. 3-pin connector option
  2. 4-pin connector option

Once you are sure about the compatibility of the fans, you should have clarity about the connection methods through which you will be able to connect them. The PWM (Pulse Width Modulation) fan or the 4-pin fan generally comprises 4 holes at the front area and then there is a provision of 4 wires from the back side as well. The same goes for the 3-pin connectors too!

Step-By-Step Guide To Connecting The Fans To Your Motherboard

Mentioned below are the steps to connect the fans to your motherboard:

Step 1: Switch off the power supply and open the CPU case

Remember that you should at first turn off the computer and only then proceed with the installation of the fan. Once the electric supply is ceased, you can then move ahead to remove the side cover. Next, you will require to connect to the motherboard. You must be aware of how to connect the 3 pins and 4 pins to your motherboard.

Step 2: Connect the fan with that of its header

Next, you will need to find a similar header that you can attach to the fan. For better clarity, you may switch to your motherboard’s manual diagram guide and then refer to the label therein.

  • SYS FAN: The ‘system’ fan connects to the motherboard through a cable which in turn is meant to monitor the speed of the fan.
  • CHA FAN: The ‘chassis’ fan is meant to cool down the whole casing.
  • PWR FAN: This is meant for the Power Supply of the CPU. If you already have a PSU fan, you may choose to connect the case fans along with them.

Step 3: Connect the 3 or 4-pin Fans

Now, attach the fan with that of the three-pin headers, or maybe, a three-pin fan with a four-pin header. In general, the black one in a 3-pin connector cable is meant for grounding, the yellow one is for the motion sensors and the red one is for the hot wire. Press it till the time the fan is establishing a secure connection with the motherboard header.

On the contrary, the 4-pin fans are usually known as the Pulse width modulation or PWM fans and come with 4 cables. They are being highly recommended these days, particularly due to their provision of having better control over the same.

Step 4: Secure the Connections

Secure all the connections properly and check that none of them is falling loose. Once done, you may choose to close the case.

Step 5: Go For a Test Run

Last but not the least, your next job will be to switch on the power and go for a test run and check if the fans are actually working or not!

How to Connect The Fans To Your Motherboard Without Any Header?

In case your motherboard does not come with a fan connecting header, there’s nothing to worry about it either! Here, you will just have to seek a fan controller with 4 pin dual connector alongside a power cable. On top of this, you will see the availability of a fan controller hub in most of the RGB fans available today.

Nonetheless, your next job will be to connect the other end of the controller to that of the SATA cable of the motherboard. You should ensure that the fans are placed correctly to make out that there is adequate airflow inside the case. Once it is done, simply adjust the fan and you are done, and that too, all by yourself!
