Budget 120mm Case Fan Buying Guide

Budget 120mm Case Fan Buying Guide

It is not always an easy task to figure out how to choose a case fan within budget. Targeting a product by checking its maximum RPM is merely a fraction of the big picture. Let us see what else determines the quality performance.

Ease of Airflow

It is obviously apparent that the airflow is the main purpose to install good 120mm case fans. Therefore, keep in mind that the airflow has a measurement of cubic feet per minute.

Each case has a different volume internally, but the midway is about 1.5-Cu.Ft. Although larger fans of 200mm can effortlessly feed the hardware fresh air, a 120mm is no less in performance, either.

With the help of the higher RPM (Revolution per Minute), a 120mm case fan with 158-ft3/min can easily move the internal volume faster.

Noise Level

Know that the noise is usually measured in decibel (dB). While many users do not mind the whirring noise produced by higher RPM generated fans, some dislike the sound.

Since the good case fans 120mm units are small, they will require steeper RPM for better airflow and static pressure.

However, noise from 16.4 dB to around 28 dB is pretty much alright if you consider the ambient sound level in the surroundings. In that case, it will not be obnoxious enough to disrupt your concentration.

If you seek a quiet product, then we suggest opting for a low RPM model.

Ball or Fluid Bearings

A fan has, like any typical fan, a mechanical system. It is made to run for many years continuously. So there are two ways to separate the case fans. Some have ball bearings, while others consist of fluid.

Case fans with ball bearings are less expensive to acquire but often break down sooner. The fluid bearings, on the contrary, are one step ahead of the game. They are popular for longevity and high-end quality.


Just because it is a PC fan, it does not automatically mean all the units will have universal shape, size, and quality. Some are adaptable to higher-level gaming CPU, while others fit standard systems.

One must choose the best cheap pc fans to receive better performance and durable life of the CPU. Always check the specifications before purchasing to ensure the case fan will, indeed, reduce overheated air from the system interior.

Remember that the cooling for the gaming station is a vital concern for a PC builder/gamer at all times. So even when affordability is in question, one ought never to compromise the quality and fitment.

Also, do not forget to check the connector style to ensure they are adjustable to the speed.

Frequently Asked Questions & Answers

FAQs About 120mm Case Fan

Is it okay to use two fans for a gaming PC?

Yes, many users, as a matter of fact, set up two good cheap case fans to eliminate the increasing heat generated by the PC systems. One can work to move out the hot air, whereas the other brings in cool air.

Should I use more than two fans for better airflow?

Frankly, it might be successful in some aspects, but it is only a waste of money. We think two at max is sufficient for optimal efficiency when it comes to balancing the CPU temperature. 

Are the bigger case fans work better?

This is a misconception many tend to believe.

The smaller case fans have similar functionalities to dissipate hot air as effectively as the bigger ones. Nevertheless, large fans are pretty quiet when operating than the smaller units.

What is a good RPM for case fans?

A good 120mm case fan should have around 900RPM, to begin with. It will create noise that is audible but meager enough to ignore. However, going higher from 900 will also increase the sound, respectively.  

Is a higher CFM better?

The CFM (Cubic Feet per Minute) is the way one measures the airflow of the fan. Usually, the higher it gets, the better, in a sense.

Nevertheless, if you consider the hardware obstacles, we think static pressure is the solution with less CFM.

Final Words

Obtaining the best budget 120mm case fan means faster runtime and noncompromising functionalities. You can own the ideal product for your gaming system if you take a little break and read our buying guide.

There is nothing like the uninterrupted, noise-free, and smooth gaming session when you know what to get. Enjoy!
