I’ve been curious about case fans since I first started building computers, and I’ve always wondered where to plug in the case fan. Is it the rear exhaust, for example? Or maybe the front panel, with the power button in the middle? Well, I decided to find out, and here’s my guide to finding the right spot for your fans.

Case fans are a necessary piece of computer cooling, but many of us are confused about where to plug them in. We know where to plug in our CPU coolers, but where to plug in our Case fans? The fans inside your case are an important part of the cooling process, but where to put them? Solving this conundrum is the focus of this guide, to help you find the best places to plug in your fans.

All video cards come with their own cooling fans, but what do you do if you want to add another fan? You can buy a third-party cooling solution, but you are better off installing the machine’s own cooling solution..

If you’re putting together a computer, you may be asking where to attach the case fans.

Alternatively, you may have had heating problems and purchased a new set of fans but are unsure how to install them in your computer.

In other words, where do I connect my case fans?

Case fans may be plugged straight into the 3 or 4 pin headers on your motherboard, however if your case fan includes PWM connectors, you’ll need to use the 4 pin headers. A Molex connection may be used to connect your case fans to the PSU.

I’ve been there, and I know how difficult it can be to get all of the answers simply browsing the internet.

You don’t have to be concerned any longer; as a computer enthusiast and builder, I’ll show you where to plug in your case fans in detail.

Don’t skip any steps since I’ll walk you through the procedure step by step.

How to Install Case Fans in a PC

First and foremost, you should be aware that your case fans may be connected using two different components.

  1. MOBO stands for Motherboard.
  2. P.S.U. stands for Power Supply Unit.

Let’s get started with the process.

The following are the steps for installing Case Fans:

1. Connect the case fans to the motherboard.

If you want the greatest potential results from your fans, you should connect them to your Motherboard.

You can control the fan speed from your motherboard BIOS if your fans are connected to the motherboard. However, you’ll need to use a 4pin connection for that choice.

Every MOBO usually comes with at least two fan headers. However, if you have a MOBO such as the B450m, you will have four pin headers.

Now search your Motherboard for the following pin headers:

  • SYS FAN is a system variable (System Fan)
  • CHA FAN is a fan club (Chassis Fan)
  • PWR FAN is a placeholder for PWR FAN (Power Fan)
  • EXT FAN is a placeholder for EXT FAN, which (Extension Fan)

If you’re having trouble finding them, look in the bottom left corner of your Motherboard. You’ll acquire one Header in no time.

It’s time to plug in the Header once you’ve found it.

  1. Every connection will have two bumps (at the beginning and end of the port) that will align it above the Motherboard.
  2. Push the connection all the way down the Header until it’s completely attached to the MOBO.

That’s it; you’ve finished plugging it up.

To keep cable management tidy, try to connect the fan to the nearest fan header. Also, get an RGB fan for your setup that is compatible with aura sync!

2. Connect your case fans to the power supply.

To connect your case fans to P.S.U., you’ll need the following items.

  • MOLEX connection with four pins (Comes with the P.S.U.)
  • MOLEX connection with three pins (Comes with the Fan)

Keep in mind that not all PSUs or Fans have the connection. However, the majority of newer units will include connections.

With a connection, you may connect your fan to the P.S.U. directly.

But what if your Fan doesn’t have a Molex connector?

The P.S.U. to Fan Pin Header Adapter is available. You may then connect your fans into the P.S.U. in this manner.

However, if you connect your fans into the PSU, there will be some back draw. You can’t adjust the fan speed, for example. The fan will constantly run at its highest setting.

Two Things to Think About When Installing Case Fans

Before you begin, think about how you’ll connect the case fans. You must have some knowledge about the fanbase.

When you open up your computer case, you’ll most likely see four different kinds of fans:

  • Fan for cooling the CPU.
  • Fan for the intake.
  • The exhaust fan is on.
  • Cooling fan (S.U.)

By just glancing at the fans, you may quickly identify the ones that aren’t working. They either won’t spin or, if they do, they produce a strange grinding noise.

Also, if any of your fans are severely blocked with dust. To prevent the heating problem, please wipe them out.

Now that you’ve learned about the many types of fans, it’s time to learn about case fans. Also, for a premium experience, look at the finest aura sync keyboards.

The intake fans will draw in cold air from your room or wherever your computer is, cool your computer components, and then push out the hot air with the assistance of the exhaust fan.

You must first learn how to face the fans before installing them.

1. Fan Direction In Cases

You must correctly configure your case fans. If you don’t, the fans will hurt you more than help you.

As a result, certain new Intake fans will feature a marking on the body indicating which direction it should face.

But what if it doesn’t work out?

You’ll need to look at the fan label or sticker in the body to do so. The sticker side is usually the front side. As a result, position the Fan in that manner.

But what if there isn’t even a sticker? Then you should search for the Fan’s spokes or mesh grill.

When installing intake fans, for example, the sticker or spokes will face inside the computer casing. Also, have a look at our list of the finest corsair keyboards, as suggested by our experts.

2. Where Should Your Case Fans Be Mounted?

In most cases, the intake fans should be on the front side of the case to let cold air in from the outside, while the exhaust fans should be on the rear to allow heated air out.

A vent will be added to certain new instances. However, don’t make the mistake of installing an intake fane there. That vent should be utilized for exhaust fans so that the hot air has more options for escape.

First, you must choose a suitable location for the Fan. So that you can easily access the Motherboard or P.S.U. while installing the Fan. This will make cable management easier for you.

When you’ve found the ideal location, line up the Fan with the four holes in the case and tighten the screws.

FAQ

Is it possible to connect casing fans to the Motherboard without using the recommended headers?

Answer: You may either connect them into your PSU or buy a Y-Splitter fan splitter.

Is it possible to connect a 3-pin fan to a 4-pin header?

Yes, you can, but you won’t have control over the fans.

Is it possible to connect my fans to the AIO PUMP Header?

No, you can’t use AIO PUMP. Headers are only for use with water coolers.

Last Thoughts

Casing fans are critical for the overall health of your PC, and they should be installed properly.

My recommendation is to do some study before purchasing fans to see which fans can be plugged into your Motherboard.
