How to Connect Extra Fans to Motherboard


Most modern PC motherboards have the necessary connectors to add extra fans. This is often a good idea, as additional cooling can improve stability and prevent overheating. In this article, we’ll show you how to connect extra fans to your motherboard.

The process is relatively simple and only requires a few tools.

How to Install a Case Fan in your PC

  • Purchase the correct type of fan for your motherboard
  • Make sure to check what kind of connection your motherboard has before making a purchase
  • The most common types are 3-pin and 4-pin
  • Once you have the correct type of fan, find an empty spot on your motherboard to connect it to
  • Most motherboards will have multiple fan headers that you can use
  • Connect the fan to the header on the motherboard
  • Make sure that the connection is secure and that there are no loose wires that could cause a short circuit
  • That’s it! Your extra fan is now connected to your motherboard and should start spinning once you power on your computer

How to Connect Multiple Rgb Fans to Motherboard

When it comes to RGB fans, there are a few different ways that you can connect them to your motherboard. The most common way is to use the 4-pin RGB header, which is typically located near the CPU socket on most motherboards. If your motherboard doesn’t have an RGB header, then you can also use a 3-pin fan connector.

For both of these methods, you will need to use a male-to-male RGB cable in order to connect the fan(s) to the appropriate header(s) on your motherboard. Another way to connect RGB fans is by using an adapter/controller. This method is probably the easiest, as it doesn’t require any special cables or headers on your motherboard.

All you need is a controller unit that supports RGB fans (most units will say this on the box) and then you just plug the controller into a spare USB port on your motherboard. Once everything is plugged in and powered on, you should be able to control the lighting effects of your RGB fans via the controller unit’s software interface.

How to Connect Case Fans to Power Supply

If you’re looking to up the cooling ante in your PC, one of the best ways to do it is by adding more case fans. But before you go and start buying fans willy-nilly, you need to make sure they’ll actually be able to connect to your power supply. Here’s a quick guide on how to do just that.

Most modern power supplies have multiple Molex connectors, which are the standard connector for case fans (and most other PC components). If your PSU only has a couple of Molex connectors and you need more than that, you can use splitters. These come in various sizes, but a 4-pin splitter should suffice for most builds.

Just know that each fan will run at reduced speed if it’s daisy-chained off another fan connection like this. Now, let’s talk about connecting the fans themselves. If your fan(s) came with 4-pin adapters (sometimes called Y-splitters), then simply plug those into an available Molex connector(s) and then plug eachfan lead into the adapter.

That’s all there is to it! However, if your fan(s) did not come with any type of adapter, then you’ll need to connect them directly into open Molex connectors on the PSU itself. Some people like using zip ties or other methods of cable management here, but it’s ultimately up to you how clean you want your build to look.

The important thing is that each fan gets its own 12V line from the PSU so that it can operate at full speed.

Fan Hub

A fan hub is a device that helps to cool a computer by drawing air into the system and circulating it through the components. It is typically composed of a metal or plastic housing with one or more fans attached. The number of fans and their size will vary depending on the model and make of the fan hub.

Some models may also include features such as LED lighting, speed control, or thermal protection. While fan hubs are not required for all computers, they can be very helpful in preventing overheating, particularly in systems that are pushed to their limits during gaming or other demanding activities. Installing a fan hub is generally a simple matter of connecting it to an available power source and mounting it inside the case.

Many newer cases come with built-in fan hubs, making installation even easier. For optimal cooling, it is important to choose a fan hub that matches the airflow requirements of your system. In general, larger systems will need more powerful fans than smaller ones.

Additionally, if you have multiple graphics cards or other high-powered components, you may need more than one fan hub to ensure adequate cooling. When selecting a fan hub, pay attention to both its airflow rating (measured in CFM) and its noise level (measured in dBA).

Fan Splitter

What is a fan splitter? A fan splitter is a device that allows you to connect two or more fans to a single power source. This can be useful if you want to add additional cooling to your computer system or if you want to connect multiple fans to a single controller.

How does it work? Most fan splitters will have multiple connectors that allow you to plug in multiple fans. The number of connectors will vary depending on the model, but typically they will have four or eight connectors.

Once all of the fans are plugged in, you simply need to connect the splitter to a power source. This can be done by connecting it directly to your PSU (power supply unit) or by using an adapter that plugs into a standard outlet. Benefits of using a fan splitter:

There are several benefits of using a fan splitter, including: -Increased cooling capacity: By connecting multiple fans together, you can increase the overall cooling capacity of your system. This is especially useful if you are overclocking your CPU or GPU as it can help prevent overheating.

-Flexibility: Fan splitters give you the ability to quickly and easily add additional cooling wherever it’s needed. For example, if you have one area of your case that tends to run hotter than others, you can add an extra fan (or two) in that area without having to rewire your entire system. -Cost savings: If you’re looking to add more cooling capacity without breaking the bank, then installing multiple smaller fans and connecting them with a fan splitter is often cheaper than buying a single largefan.

Additionally, many PSUs come with built-in fan splitters which can save you even more money.

Fan Splitter 4-Pin

A 4-pin fan splitter is a device that allows you to connect two 4-pin fans to a single 4-pin header on your motherboard. This is useful if you want to add an additional fan to your computer, or if you need to replace a damaged fan connector on your motherboard. 4-pin fan splitters are available from a variety of sources, and they typically cost around $5.

You can find them at most computer stores, or online from retailers such as To use a 4-pin fan splitter, simply connect the two fans that you want to use to the splitter, and then plug the splitter into the 4-pin header on your motherboard. It’s important to note that both fans must be identical – that is, they must have the same make and model number.

If they are not identical, then one of the fans will not spin correctly. Once you’ve connected the splitter and turned on your computer, both fans should start spinning. You can then adjust their speed using your computer’s BIOS or by using software such as SpeedFan (Windows) or smcFanControl (Mac OS X).

Pc Fan Hub

PC Fan Hubs are devices that allow you to control the speed of multiple fans connected to it. This can be useful if your computer is getting too hot, or if you want to make sure that all of your fans are running at the same speed. Most fan hubs will have a knob or switch that allows you to adjust the speed of the connected fans.

Some models also have LED lights that indicate which fans are running at what speed. Fan hubs typically support 4-8 fans, but there are some high-end models that can support more. If you have a lot of case fans, then a fan hub is definitely something you should consider getting.

Installing a fan hub is usually pretty simple. Just connect all of your case fans to the hub, and then connect the hub to an available power header on your motherboard. Once everything is plugged in, you should be good to go!

How to Connect Multiple Fans to Motherboard

Are you a PC gamer? If so, then you know that one of the most important aspects of a successful gaming experience is having a well-cooled system. And if you want to cool your system properly, then you need to know how to connect multiple fans to motherboard.

Most motherboards will have two or three fan connectors. The number of fan connectors will determine the maximum number of fans that can be connected. For example, if your motherboard has two fan connectors, then you can connect up to two fans.

The first step is to identify where each fan connector is located on the motherboard. Most motherboards will have labels next to the fan connectors that indicate which connector is for which fan. Once you know where each connector is located, it’s time to start connecting the fans.

If your motherboard only has two fan connectors, then you’ll need to decide which fans are going to be connected to each connector. In general, it’s best practice to connect larger and/or more powerful fans directly to the power supply via dedicated fan headers. This ensures that those fans will always have enough power and won’t cause any potential problems with other components in your system.

Should I Connect Case Fans to Motherboard Or Power Supply

There are a few things to consider when deciding whether to connect your case fans to the motherboard or power supply. If you have a fan controller, then connecting to the motherboard may be the best option. This way, you can use the controller to regulate the speed of the fans and make sure they’re not running too fast or too slow.

Additionally, if your motherboard has RGB headers, then connecting your case fans to it will allow you to control their color and lighting effects. On the other hand, if you don’t have a fan controller and don’t care about RGB lighting, then connecting your case fans directly to the power supply is probably the easiest way to go. This way, they’ll always be running at full speed and you won’t have to worry about fiddling with any settings.

Simply plug them in and forget about them! Ultimately, it’s up to you which method you prefer. If you want more control over your fans, then go for the motherboard connection.

Otherwise, direct connection to the power supply is probably simpler and easier.

How to Connect Extra Fans to Motherboard


Where Do I Plug in Extra Fans on Motherboard?

Assuming you’re referring to chassis/case fans: Most motherboards will have a few different options for connecting case fans. The most common connection is a standard 3 or 4-pin fan header, which you can find dotted around the motherboard.

Some boards also include dedicated CPU fan headers, which are usually located near the CPU socket. If your motherboard doesn’t have enough fan headers for all the fans in your case, then you can use fan splitters to connect multiple fans to a single header. Just be aware that this can put extra strain on the header and may impact its performance.

Can I Plug 3 Fans into One Header?

Yes, you can plug three fans into one header, as long as the header supports enough power to run all three fans. Most headers have multiple fan connectors, so you can simply connect all three fans to separate connectors. If your motherboard only has one fan connector, you can use a Y-splitter cable to split the single connector into two.

This will allow you to connect two of the three fans directly to the motherboard, and then connect the third fan to one of those two with another Y-splitter.

How Many Fans Can a Motherboard Handle?

A motherboard is the main circuit board in a computer. It houses the CPU, RAM, and other important components. Most motherboards have three or four fan headers.

Depending on the size and design of the motherboard, it can handle anywhere from one to eight fans. The number of fans a motherboard can handle is determined by the number of fan headers it has. A header is a connection point on the motherboard where a cable from a fan can be plugged in.

Most motherboards have at least three fan headers: one for the CPU cooler, one for an optional system fan, and one for an auxiliary or water-cooling pump (if applicable). Some high-end motherboards may have up to eight fan headers. To determine how many fans your motherboard can support, simply count the number of available headers.

If you want to install more fans than your motherboard has headers for, you’ll need to use a Fan Controller or Hub. These devices allow you to connect multiple fans to a single header using Y-splitter cables.

How Do I Connect Two Cpu Fans to My Motherboard?

Assuming you would like to know how to connect two CPU case fans to your motherboard, below are instructions on how to do so. First, identify if your motherboard has three-pin or four-pin fan connectors. Three-pin fan connectors are usually used for the power supply unit (PSU) and chassis fans, while four-pin fan connectors are reserved for the CPU fan.

If you’re not sure which type of connector you have, refer to your motherboard’s manual or look up its specifications online. Next, locate an available fan connector on your motherboard and insert the first CPU fan lead into it. If your motherboard doesn’t have enough room for both leads, you can use a Y-splitter cable to connect both fans to a single header.

Once the first lead is connected, do the same with the second one. If your motherboard only has three-pin headers, that’s all you need to do! However, if it has four-pin headers (or if you’re using a Y-splitter), there’s one more step: connecting the PWM wire.

This fourth wire allows your computer to control the speed of the fans based on how hot your CPU is running. To connect the PWM wire, simply insert it into the fourth pin on each header. Once everything is plugged in, close up your computer case and boot up your PC.

Your BIOS should automatically detect and start controlling both of your new CPU fans!


Assuming you would like a summary of the blog post titled “How to Connect Extra Fans to Your Motherboard,” here it is: Most motherboards will have three or four fan headers, which should be enough for the average PC build. However, if you’re looking to add more cooling to your system, you can always connect extra fans directly to the motherboard.

Doing so is pretty simple and only requires a few extra supplies. First, you’ll need some male-to-male jumper wires. These can be found at most electronics stores.

Once you have those, just connect the positive (red) wire from each fan to a free header on the motherboard. Then, connect all of the negative (black) wires together and attach them to a ground point on the motherboard. That’s it!

Just keep in mind that connecting too many fans directly to the motherboard can put strain on the power supply, so make sure not to go overboard.
