Will Your Motherboard Support RGB Fans? How To Find

Based on the type of RGB fan that your motherboard uses, the answer to this question shall vary! If you do not have an RGB header in your motherboard, chances are that the fan will work even if the RGB isn’t working!

You can easily connect to them with just the LED cable.

The best way through which you can easily identify if your motherboard is going to support the RGB fans is by refering to the user manual, or just do a visual inspection. The RGB headers are primarily labelled as JRGB 1, JRGB 2, RGB_Heafer 1, RGB_Header 2, etc. You will find these RGB headers to be located near the edge of the motherboard, and you must also know that a few mid to high-end motherboards may have 2 or more RGB headers on them.

3 Pin Vs 4 Pin Vs 5 Pin RGB Headers – When To Go For Each?

Most of the motherboards usually come with 3 pin or 4 pin RGB compatible motherboards, and there are only a few high-end motherboards which may have the 5 pin headers. In general, the RGB B fans with the 3 pin cables are the most commonly used models. They are also known as DC fans since a user can control the speed by the voltage itself. If you are looking for something very basic, good to serve your purpose, as well as, affordable at the same time, go for the 3 pin RGB fans!

A 4-pin RGB fan is going to work well for you if you are looking for a model with a higher CFM.

Step 2:

Usually, you will have two 3 or 4 pin cables running from your fan. While the wider one will control the RGB lights, the smaller one will just control the fan motor. If you have empty RGB headers on the motherboard, just do the pointers as stated below:

  1. At first, connect the RGB connector of the fan to the RGB or JRGB_header
  2. Now, connect the fan connector to the CHA_FAN or SYS_FAN socket present on your motherboard

Plug the connectors of the RGB fans to SYS_FAN1, 2, 3 or CHA_FAN1, 2, 3 sockets of the motherboard

Step 4:

Now, connect the controller to that of the female connector of the splitter.

Step 5:

Last but not the least, attach the controller to the power supply.

Common FAQs related to RGB fans

1.What is the basic difference between RGB fans and LED fans?

The LED fans usually come with just a specific color, and thus, the RGB controlling phenomenon is not applicable to these items. On the other hand, the RGB fans usually display three different colors – Red, Green or Blue and despite them being static, we can easily choose to change these colors as we wish to!

2. RGB or ARGB lights – Which one is better?

ARGB comes with adressable LED lights while the static RGB lights do not have them. As a result, most of the users tend to prefer ARGB lights over the latter. Visually, the only difference that the RGB lights have with the ARGB lights is that the former comes with four wires, while the latter comes with three cables. These RGB lights need a controller, which does not use a third party application to perform its functionalities.

You must go for the RGB lights if you think that you are not having any mechanical control over the lights. Besides, RGB lights are the only option available for you if you have a non-RGB motherboard. On the contrary, you may choose to go for the ARGB lights if you are fine with adding a switch to control the third party app.


Know that connecting one or for that matter, two RGB fans to the motherboard is nothing rocker science. It is damn easy and you will just need to note the aforementioned tips and tricks to get it done in no time! Read more amazing content from g-prime.net
