How To Connect RGB Fans To The Motherboard?


Many people claim that building your PC is just like building your own Lego set. We have a general idea of where each piece goes and can figure out the rest through the diagrams if necessary.

However, what a lot of people don’t tell you is, unlike a Lego set, if you press too hard on your PC components or place them in slots that are not meant for them, you will likely permanently damage your components and will have to buy new ones; only they are very expensive to buy in the first place. You can follow the proper ways to make sure your RBG fans are connected to the motherboard correctly.

Does My Motherboard Support An RGB Fan?

When purchasing an RGB fan, the first thing you should check is its compatibility with your motherboard. In case it is not, your fan might still run, but you will not be able to enjoy the fancy lights that turn up with an RGB fan. Always check if your motherboard has an RGB header to connect your fan’s LED lights.

If no such header exists on your motherboard, you will have to buy a different model of RGB fan that comes with a controller plugged into its MOLEX cable from the power supply. This will ensure a separate power supply to your Led cable, and as such, you would not need to have a header placed on your motherboard.

How Can We Connect RGB Fans To The Motherboard?

Normally, there are three different types of connections when setting up RGB fans onto your motherboard. They are:

  1. 3 – pin RGB fans
  2. 4 – pin RGB fans
  3. Connecting to a Motherboard without headers

Connecting and running a 3 – Pin and a 4 – Pin RGB fan to a motherboard is quite easy, and you do not require any additional equipment. However, connecting your RGB fan to a motherboard that does not have a header to connect to gets a little tricky.

Steps To Connect A 3 – PIN RGB Fan

  1. Separate the case from the packing and ready the fan alongside the motherboard.
  2. Read all the instructions provided with the manual, even if you think you have understood everything there is to know about connecting your RGB fan.
  3. Usually, the motherboard manufacturers will mark the pins designated to connect your RGB fans. They are 3 elongated pins standing straight from the motherboard.
  4. Place your RGB fan pin on it and fix it tightly to avoid loose connections.
  5. Once the connections are done, place the fan in the case provided and ready your motherboard.

3 – Pin RGBs are also called DC fans and are generally cheaper compared to 4 – pin RGBs. These fans are controlled by voltage and are generally much simpler in functioning. However, the disadvantage is that they produce a lot of noise when running.

You can connect a 3 – Pin RGB fan to a 4 – Pin slot on the motherboard if that’s what was provided to you. But it is recommended that you only do it with 3 – Pin slots. Usually, the 3 – Pin connector is much smaller than the 4 – Pin connector while the design is almost the same. A 3 – Pin RGB connector has three square-shaped holes connected to the front and wires separately attached to each of the holes. The black wire is for ground, the red wire for power input, and finally, the yellow wire for speed sensor purposes. Always ensure that the power is turned off before removing or mounting your RGB cable onto your motherboard.

Steps To Connect A 4 – Pin RGB Fan To Your Motherboard

  1. Separate the 4 – Pin RGB from the packing and place it alongside the motherboard. Make sure that the product is not damaged.
  2. Take out the instructions manual and read all instructions carefully to ensure that you do not make any mistakes.
  3. Most motherboards come with labels that denote slots for RGBs. Look for these slots to put your 4 – Pin RGBs.
  4. Once identified, insert your fan’s connector onto the header present on the motherboard.
  5. Make sure that you press just enough to fix the joint and keep it steady and not too tight that you damage the joint altogether.

Unlike the 3 – Pin RGB fans, the 4 – Pin RGB Fans are called pulse width modulation fans. They are significantly more powerful since they come with a higher RMP rating. 4 – Pin RGBs are more widely accepted due to the greater control they provide to the user. They are generally less power-consuming and make much less noise than 3 – Pin RGBs.

Steps Involved In Connecting RGB Fans To A Motherboard Without Headers

In case your motherboard does not come with a header to connect your RGB fan, you will need to use an RGB fan with a 4 – dual pin connector and a power cable.

  1. Take the 4 – Pin dual connector and connect your RGB to it.
  2. Now, insert the other remaining end to the RGB fan’s controller.
  3. The other end of the controller has a slot for power input to connect it with a power cable.
  4. The other end of the power cable goes to the SATA cable of the power supply. This is responsible for providing a power supply to your RGB.
  5. Once all these connections are properly fixed, you can turn on your device and let your fans run.

Can you plug a fan into RGB header?

If you have an ARGB fan, you can connect the fan to the RGB header. However, the RGB header needs to be a 3-pin 5V header and not the 4-pin 12V header. If you are trying to insert a normal case fan to the RGB header, it is not recommended.

Where do PC fans plug into?

CPU cooling fans should ALWAYS be plugged into the header that is specifically labeled “CPU Fan” and not “CPU Optional” or any other header.

Are RGB fans 12V or 5V?

Compatibility. RGB devices are compatible with 12V headers that have 4-pins and are present in many motherboards nowadays. In fact, more motherboards have 12V 4-pin RGB headers than the newer aRGB headers due to their lower cost. RGB 12V devices are NOT backward or forwards compatible with the 5V aRGB headers.

Can you connect a 3 pin RGB to a 4-pin motherboard?

You can plug a 3pin into a 4pin header for Fans but not ARGB You can’t. 3-pin ARGB headers are 5V with a 5V pin, a single data pin, a blank spot and a ground pin. 4-pin RGB headers are 12V with 12V, red, blue and green pins. Plugging an ARGB strip into a non-ARGB header will blow out the strip.

The cable can be connected to the standard three-pin plug or the three-pin “VDG” plug for addressable RGBs using both three-pin sockets. The arrow on the socket indicates the correct plug-in direction. This cable is mainly used in gaming or case modding. The cable is only suitable for 5-V LED lighting.

What is VDG plug?

The VDG is for some of the Gigabyte and Aorus motherboards that only used the 3 pin connection. other brands all used the 4 pin connector and Gigabyte swapped to that style on the more recent boards. You need to use the same connector that it shows for other brands that uses the 4 pin connector with 1 pin missing.

How can I use RGB fans without RGB header?

Conclusion

Connecting your RGB with your motherboard should be like placing Legos. However, do make sure that you don’t put too much pressure on your connections that they break. Always be delicate with your computers. Once you figure out what type of RGB you will use and whether your motherboard has an RGB header, fixing the equipment only takes a couple of minutes.
