Are Case Fans Important While Gaming?

Gaming units are not the same as a standard PC. They are usually equipped with memory cards and graphic cards. While these accessory cards allow the units to perform better, optimizing them for gaming, they also come with a major drawback. That is, they generate a lot of heat. This heat not only slows down the functioning of your unit but may also cause long term damage to your device.

This is where case fans come in. Case fans are devices that cool your unit down. They get rid of the extra heat, which may damage your system. A good case fan is extremely important if you want your gaming unit to last longer and maintain its high-quality performance. A gaming unit can function without a case fan but its functionality just won’t be the same. So the answer to the question is yes, case fans are quite important for gaming.

Why Did These Case Fans Make Our List?

This article features a list of some of the best 120mm case fans available. These products have not been randomly picked from a sea of products. Instead, they have been carefully chosen on the basis of some ideal features that almost all these products share. Here are the features that were kept in mind while choosing these products:

Cooling Capacity

As the name implies, the cooling capacity of the fan is basically its capability of dissipating heat from your system. A product with greater cooling capacity will be able to keep your unit at lower temperatures for a longer span of time. All the products on our list are designed to provide users with the best cooling capacity.


When you invest in a product, you want good, lasting performance. What use is an item if it works well, but only for a day? You’d have to invest in another one, wasting money on another product after such a short time. For this reason, the products on our list all guarantee a great durable build, which will last you longer than the standard case fans.

Quiet Functioning

Fans are known to be noisy, no matter what device they are for. While gaming, users need to focus all their attention on the game. But the noise from fans can be a great disturbance. In order to ensure you do not have to deal with that problem, we have picked units that provide you with the quietest possible functioning.

Review of the Best 120mm Case Fans

A lot of users spend a great amount of time just looking for the perfect case fan for their unit. Finding the right unit can be a painstaking task. In order to cut the process short, we have picked out some of the best products to invest in. All you need to do is find one that meets your criteria.

  • Can easily function in spaces as restrictive as 3cm
  • Comes with striking LED lights that add a fun aspect to the system
  • Translucent fan allows LEDs to produce a dramatic effect
  • Designed with custom-molded blades that allow a high volume air delivery
  • Ideally designed for the rear, as well as top mounting, but can be used on sides and bottom, as well


  • Installation process might be tricky for some users
  • The plastic on the corners seems too thin to support the fan for a long time
  • Can only be connected to the headers and not into a plug with connectors

What Recent Buyers Report

This unit is one of those that is exceptionally well-known amongst its users for the outstanding satisfaction it provides. Users have been greatly impressed by how silently it cools their systems, bringing them to just the right temperature. They were also greatly impressed by the bright LED lights that simply added to their experience.

Why it Stands Out to Us

If you ask the users, there is simply nothing to dislike about the unit, and we entirely agree with them. But what we really like about it is the translucent design of the fan itself. The opaque fans usually cut off the LED lights, reducing their impact, but the translucent fan further adds to the effect.

Who Will Use This Most

Given the ideal design and functionality of this unit, we think this is a unit designed for all sorts of users. From beginners to professional gamers, all PC users would find this 120mm case fan to be the perfect addition to their system.

Bottom Line

They have also commended it on the great variation of colors that it provides.

Why it Stands Out to Us

There is a lot that this unit has to impress its users. But looking at its features, what really impresses us most is its two-way installation. Users who use two different fans to blow out hot air and draw in cold air can simply use this one to provide them with both.

Who Will Use This Most

This product has a long list of features. This allows it to be used by a great number of users. But those that need a case fan that can be conveniently installed on the top with the best results would find that this is absolutely the perfect unit for them.

Why it Stands Out to Us

There is a lot that this unit offers to its users, but the best of these features, according to us, are the two silent mode adapters it comes with. These adapters ensure that the noise of the fan is the least of your worries, and you can use your system in peace.

All in all, it’s a great product at a great price.

Benefits of Investing in a Quality Case Fan

It is true that a gaming unit can function on its own without attaching a case fan to it. Then why invest in a case fan? There are chances that some of you are still wondering if a case fan is worth investing in. In order to clear your doubts, here are the benefits you can avail by buying one of these top-quality products.

Better Performance

No matter how good your unit is, even without the addition of accessory cards, it generates a considerable amount of heat. This heat can cause your system to slow down. This slowing down may be okay for some, but those that require an efficient functioning of their CPU will find that a case fan efficiently gets rid of this excessive heat. Without heating up, your unit can perform a lot better.

Longer Life

The heat produced by the system does slow down the performance. But if the temperature is left consistently high over a long period of time, it may also cause permanent damage to your system, which can’t be reversed later, eventually requiring you to get it replaced. With a case fan, the heat is constantly dissipated, keeping the temperature within safe ranges, ensuring a longer life for your unit.

Greater Control

If you invest in a good quality unit, you will be able to control the speed of the fan attached to your system. While you use your PC for general purposes, you can keep the fan on low, since not a lot of heat is produced. But when you decide to overclock your unit, you can turn the speed to high to ensure sufficient heat dissipation. This way, you can save energy.

How to Install a New Case Fan

Those who have used case fans previously may not find installation to be a hard task. But for those who are using them for the first time, it may be confusing. If you, too, need help installing these units, then do not worry. Here is a quick and easy guide on how to do it.

1. Before you do anything, make sure that your PC is powered off. To be on the safe side, unplug it from any power source, as well.

2. Mount the fan in a position such that the screws line up with the holes in the case. Once lined up, tighten the screws into position.

If you have friction clips instead of screws, simply snap them into place.

3. Connect the pins of the fan to an unused header on the chipboard. The headers are usually pin specific, but a three-pin pan can be used with a four-pin header and vice versa.

4. Plug your unit again and power on the device. The fan must start functioning with your system. And just like that, you’re good to go.

If the above instructions don’t help you with installation, then you may refer to the video below for a more illustrated guide.


If you’re tired of your unit slowing down due to the excessive heat and can’t overclock it without having to compromise on the functionality, then it’s about time you invest in a case fan. With simple consideration of a few key features, you’ll be able to get the best out of your gaming system and enjoy your gaming sessions like never before.

People Also Ask

Case fans are very important for your gaming system. You need to pick the right unit and the right number of fans in order to ensure optimum functioning of your gaming unit. To help you clear all your queries regarding these fans, we have answered some of the most frequently asked questions.

Are 140mm Fans Better Than 120mm?

When comparing the two sizes, the winning fan depends upon what you require from your unit. At the same RPM, 140mm fans usually deliver better cooling compared to a 120mm fan. But when functioning, the 120mm fan moves at a greater RPM, providing the same amount of cooling effect. But since it works faster, it produces a lot more noise. So in terms of quietness, yes, the 140mm fans are better than the 120mm ones.

Are Bigger Case Fans Better?

A lot of people believe that a bigger fan works better, but that is not entirely true. A smaller fan can efficiently dissipate heat from your system just as well as a big one. The difference lies in the noise produced by the fans. Bigger fans are generally quieter than smaller ones. So if your unit is big enough to support a bigger case fan and you do not want to add noise, then a bigger fan should be your ultimate choice

How Big is a 120mm Fan?

The 120mm case fan speaks for itself. It is 120mm in size. Converting into inches, these units are about 4.72 inches. This size is roughly the same as that of a standard compact disc. This small size of the fan is what makes it efficient and appropriate for the job.

Are Two Fans Enough For a Gaming PC?

While one case fan can work well enough to lower the temperature for your gaming unit, two will definitely work better. A lot of users use two fans for their systems. One of them works to push the hot air out of the unit, while the other pulls the cold air in, allowing more efficient cooling than a single fan.

Are More Case Fans Better?

We all think the saying “the more, the merrier" goes for everything. Well, that may be true in some respects, but only to a certain extent. While using more than one case fan can definitely improve the impact of heat dissipation, using excessive fans may be nothing but a waste of money. Your unit requires a certain temperature for its optimal functioning. And if two fans can work enough to keep it at that, then you do not need any more.
