What is a Case Fan?

A case fan is also called a system fan. It is located inside a computer and is usually attached to the front, or in some cases, back of the case. The fan’s job is to bring cool air inside the case while also blowing hot air outside. This process ultimately helps in balancing the temperature of your PC or laptop. Furthermore, if this process is not executed correctly, then the adverse effects like overheating can reduce the life of your device. Hence, an effective cooling system and air circulation are essential for the durability of your PC.

How Do I Choose an 80mm Case Fan?

There are some qualities or features that you must consider before buying an 80mm case fan in order to get the best out of your product.

Noise Levels

Before buying a case fan, you should check its noise level because people who are frequent users like professionals or gamers have often complained about high noise levels. Hence, you should make sure the case fan you are buying has low noise levels.

Speed

A fan’s speed is measured in terms of Revolutions Per Minute (RPM). The higher the speed you want, the more the RPMs you should look for. A higher RPM is also better because it means that the fan pulls in more air per minute as compared to a lower RPM fan.

Intake or Exhaust Fan 

Some fans are intake, while others are exhaust. You should be mindful of this before buying the fan. Ideally, the ratio should be 1:1, but it can vary depending on an individual PC's requirements. 

Airflow Fans or Static Pressure Fans

Another essential thing is the kind of fan you use. If there are no obstructions around the fan, then an airflow fan will be good enough, but in the case of obstruction, it is better to get a static pressure fan. The difference between this is the shape of the blades.

CPU Fan vs. Case Fan - What's the Difference?

A CPU fan is a fan that stands over your CPU. It will have a base that sits over your CPU, which is usually made of copper, aluminum, or a mix of both. The base will have heat pipes with blades, where the fan sits. The heat is moved from these pipes to the blades of the cooler. The fan pulls the heat away from these blades and into the air to be pulled out by the case fans. In this scenario the case fan is an outtake fan. However, depending upon the area where case fans are attached, they are intake or outtake fans.

Case Fan 3-Pin vs. 4-Pin - Which is Ideal and Why?

Some case fans have 3 pins while others have 4 pins. This basically affects the ability to be controlled by remote or by a third-party software. A regular three-pin case fan will have wires for ground, power, and tach – it relies on data from your software or motherboard. On the other hand, the four-pin fans will have an additional wire for Pulse Width Modulation (PWM) Control. This additional fourth wire enables your fan control software or motherboard to control or adjust the speed of your case fan. Hence, it is better to have the fourth pin in your case fan.

How to Install a Case Fan

It may look easy to install a case fan, but it can be quite complicated, and if not installed properly, it can cause problems for both the case fan and your PC. Hence, you should carefully follow the instructions.

1.     Open the easy service flop of your CPU.

2.     Figure out where you want to place the case fan and for what purpose – intake or outtake.

3.     Figure out where you want to put or roll the cable in your system.

4.     Place the fan in its place.

5.     Make sure the airflow direction is in accordance with your needs.

6.     Screw it into its place properly and tighten it so you can minimize vibrations that pass through the system.

7.     Install any other fans you want by following the same instructions.

8.     Once you are sure that the fans are installed properly, just attach the system to a power source. 

9.     Make sure your unit is properly sealed after the installation to avoid any electrical issues.

Conclusion

If you want to prolong the life of your devices and make sure they work efficiently over long periods of time, then a good-quality case fan is essential. They are not just effective, but also silent and can be controlled by remotes to increase convenience. Hence, you should seriously consider them.

People Also Ask

It can be a little tricky to understand the concept of case fans if you are new to it, and even if you understand the specifications of the fans, it can be a challenge to understand how to make them compatible with your device. Hence, we have answered some top questions for you.

How Many Case Fans Do You Need?

It depends on your own personal requirements and hence, if you are not sure, you should ask an expert. However, normally you need cases with space for at least three fans. The number of fans can be inquired about from the seller you are buying the case from. 

Which Way Do You Install Case Fans?

The fans can be either intake or outtake. However, the way you chose to install the case fan depends on two factors; your personal preferences and your system's design. We recommend looking for professional advice or help regarding your specific computer system.

How to Measure a Case Fan

Measure the horizontal or vertical distance between the screw holes. A quicker way to do this can also be to measure the diagonal length of the case, which is the ideal way used by most people. 

How to Control the Case Fan's Speed

If you have a three-pin fan, you cannot control fan speed. However, four-pin fans with PWM, allow you to use fan controllers or external software to control speed. This is also why we recommend four-pin fans over three-pin fans.
