Case fans are the eminent reason behind dissipating the heat out of the CPU. Installing this unit is arduous for some users who come with questions like Where to plug in case fans on the motherboard.
There are a couple of technical points that you may need to know before we look into Where to plug in case fans on the motherboard. First is the casing for the Fan to sit inside the CPU. Secondly, the power supply and connection it gets from and its connection. We will look into this as well as detailed steps of fitting these fans in this article.
So, Where to plug in the case fans on the motherboard?
No matter what Case fans you use, they can be fitted directly to the motherboard using a 3-pin or a 4-pin connector and make them sit in the respective casing. Note that using a Molex connector is important here. Generally, a motherboard has multiple pins to ensure several cafe fans if needed.
You can easily find Molex headers on your motherboard with 4 pins emerging out of the board. You can also see multiple headers with names like SYS_FAN and CPU_FAN, implying separate headers to connect system-related and CPU cooling fans.
[Easy Steps ]- How to Plug in Case Fans on Motherboard?
Most often, knowing where to plug in case fans on the motherboard may not be enough to fit these fans. You may get it clear by going through detailed steps for the same. Here, we came up with easy steps for you to comprehend the process:
Step 1: Discern the right direction to fit the Fan
Casing fans are designed to take the air in one direction only. So, it is important to determine the right direction to fit the Fan in. Right fitment can take the air out of the PC. Otherwise, it pulls outer air in, leading to inefficiency. Most often, these fans come with arrows on them, determining the direction of airflow. Even if it is not provided, you can connect it to the DC power supply to test the direction.
Step 2: Place it and Screw
With the proper idea of air direction, it is time to place the case into its position. Mostly it needs to be fastened with 2-4 screws to the CPU. These screws are easily available. Thankfully, some fans come with screws out of the box too. Now that you may need to clean the area and the Fan to remove dust. Moreover, ensure the Screw is appropriately tightened. Too much tightness may also affect efficiency.
Step 3: Ensure proper inflow for the Fan (s)
To remove heat properly, the CPU must ensure to have a proper input area too. This especially turns crucial when there are multiple fans on your computer. This is because multiple fans with improper alignment and input can lead to a negative impact on the processor.
Step 4: After casing, it is time for the Power Supply.
Once the setting of the Fan is ascertained, we may now look into the power input for them. Generally, there are multiple Molex pins (3 pins or 4 pins) on the motherboard that can give power inputs to internal devices. Check out the pin of the case fan and connect to a Molex pin to complete the process.
Note: Case fans can be of three types, and their function may vary slightly from each other. It is important to identify what you exactly want and then fit it to your PC. Based on the type of fans, the number of pins and other factors too are affected.
By now, we hope you understand where to plug in case fans on the motherboard. Not only the location, but we also elucidated steps in detail about how case fans can be successfully fitted into the motherboard or the CPU. Check out the detailed steps and also a set of frequently asked questions and other insights to better understand the architecture of case fans and their fitting to the system.
