Connecting fans are a problem for both PC builders and those who buy their computers on a shelf. It is not clear where the fans can be connected, and no one wants to risk damaging his equipment by connecting fans in the wrong place.

There may be many reasons why you might want to connect if you are a fan on your PC. You may be building a PC and want to make sure there is proper airflow in your unit. It could also be that your PC is suffering from thermal throttling and you want to provide it with that bit of cooling power.

If you are wondering where to connect if you are a fan, we here at DiamondLobby have compiled this guide as a complete tutorial. First, we look at all the places you can connect fans if possible. Then, we explore why you might want to have more followers on your desktop.

However, it is important to note that trial fans are not the only solution for a very hot PC. It is quite possible that even after installing more fans, the performance of your PC does not improve much. Of course, there are other ways to reduce the amount of heat generated by your PC, such as cleaning your photo card.

So, make sure you do not spend more money than you should by first asking yourself how many fans you need.

Two places where to plug in case fans

As the title shows, there are two different places where you can connect in case fans. The first is the power supply, which is a simple solution. However, it also has some drawbacks. The second option is to connect the case fans to the motherboard. Let’s look at both options.

Connect Case fans to Your Power Supply

You might be thinking about where to plug in case fans?

The easiest way to connect your fans is to plug them in. To do this, your motherboard requires Molex connectors. Molex connectors have four pins and can be used to power up additional peripherals in your building.

However, you will also need 3-pin adapters for your Molex fans. You will attach the fan to the adapter, and then connect the adapter to the Molex connectors at the PSU. Many fans came with these adapters in the box. In some cases, however, you may need to purchase adapters separately.

Just remember that some PSU models do not come with Molex connectors. If you have a modular PSU, you should be able to attach Molex connectors to your PSU. If your PSU doesn’t come with any Molex connectors, you have no choice but to connect fans to the motherboard.

It is also important to remember that if you attach your fans directly to the PSU, you will not be able to control their speed in any way.

Fans will always be running at full speed, which can cause a lot of noise if you have more than 2 fans in your building. Of course, if you do not see the reason for controlling the speed of your fans, this should not be a problem.

The biggest advantage of connecting when fans are on your motherboard is the fact that you can easily control their speed. This can be done both with the BIOS and with specific applications that you can download.

To connect your fans to your motherboard, you need to find two fan titles. These will be labeled SYS_FAN (System Fan) and CHA_FAN (Chassis Fan). You can also find other topics if you have a top mom board that supports more fans.

This is a mistake to add fans to your mom board. There is a limit to the number of followers you can connect with. Yes, you can connect more fans to the network. Also, there are workarounds that can be used to connect additional followers directly to the motherboard.

However, workarounds come with their own risks. There are many ways to put case fans on the motherboard, and you should choose the most appropriate one.

Why you should have more case fans

It can be difficult to recommend the exact number of trial fans you should have on your PC. This is because adding a fan base to your site becomes ineffective after a certain point. That being said, there are some situations where it may be beneficial for you to have more than two fans who are considered standard for most PCs.

Here are a few situations in which you should consider adversaries of additional cases:

  • You will shut down your PC over and over. Excessive skipping is likely to always lead to higher temperatures, and it would not be painful to have additional case fans to emit more heat.
  • You have a really good plan that you plan to push to the limit. When parts require more energy, they also produce more heat. Having extra case fans is sometimes necessary unless you have a very efficient cooling system.
  • The temperature of the room may be high where you are using your computer.


In short, you can connect in the case of fans on both the motherboard and the PSU. They both come with their own pros and cons, and when you last hang out it’s up to you.
