Best 120MM Case Fan

Your gaming PC needs adequate cooling for great performance. No matter how great the other components are, it would be best if you still had the right environment for them to do their best. When it comes to computers, that surrounding is one where the temperatures are controlled, and with the best 120mm case fan, you will be able to achieve this.

PC case fans keep your system cool during operation. Without enough cooling, your PC will heat up very much, which can turn off or even some permanent damages to your build. When your PC is properly cooled, all of your vital components, the CPU, the GPU, RAM, and more, perform well irrespective of what you are doing. Furthermore, whether you are a semi-regular user or a gamer that plays regularly, cooling is vital.

The process of selecting the best case fan can be draining, especially since the market is overflowed with options. We have compiled these reviews and everything you need to know before buying the right fan. Let's begin!

The Corsair LL120 3 Pack Case Fan has two lights loops, one around the rim and one in the hub, with 16 RGB LED lights combined. Every LED light can be controlled individually, providing complete control over the look of the lights in your fan and the capability to create limitless combinations of colors.

The fan operates at up to 1500 RPM and can perfectly push up to 43.3 ft3/min of air through the PC case. Although this is not the best on our list, it is enough to clear the out of either a mid-tower or even super tower case fast enough to keep most hardware cool for better performance. Besides, the Corsair LL120 3 Pack Case Fan also pushes air with 1.61mm H2O of static pressure, which is sufficient for most radiators, plus it is generally quieter.

Although the RGB fans are sold separately, we recommend you check out the manufacturer's "starter pack." The pack comes with three fans, plus a lighting Node Pro. It would be best if you plugged every fan into the Lighting Node, which acts as a hub and lets you control the custom lighting via Corsair's CUE software. Additionally, though the combo pack comes with an RGB hub, you need to ensure you have one if you buy these RGB fans separately, that is, if you want to utilize them to their fullest.

  • Pros
  • Operate at very little noise
  • Offer a variety of RGB lighting to choose from
  • You can control the lights individually through software.
  • High airflow fans worth the price
  • Cons
  • Louder at mid-range speeds

No products found.

If you are looking for the best 120mm case fan with independent LEDs, we recommend the Cooler Master Dual MF120R 120mm Fans. This fan pushes an amount of air of about 110 ft3/min, allowing you to keep even the hottest components cool in any situation this fan will fit into. If there is a tendency to accumulate heat in your case, resulting in temperatures spiral out of control under sustained loads, then this is the case fan you need for your hardware cooling.

The Cooler Master Dual MF120R, 120mm Fans, runs at low (RPM) speeds. The maximum RPM of this fan is 700RPM despite the insane airflow, meaning the fan operates silently, measuring in at only 19 dBA. The package comes with two fans which are plain black, red, or blue LED light versions.

The main drawback with this fan is that it is not designed with any radiators, making it very poor with static pressure and does not push the air for good airflow. This drawback means that any obstacles, including drive bays or poorly managed cables, can interfere with the fan's performance.

  • Pros

Also, the color customization disposable corners installed to anti-vibration pads easily allow you to suit your fans with the best parts of your build.

Corsair doesn't utilize a blade design like similar models such as Silent Wings 3, making them louder under that category. However, it doesn't produce much noise when compared to fans that operate on bearings. Most users praise it for its silent operation.

  • Pros
  • Produces less noise
  • Has a longer lifespan
  • Offer great performance, i.e., cooling.
  • Great for cooling case mounted radiators
  • Cons

Factors to Consider When Buying the Best 120mm Case Fans

1. Bearing type

The bearing used in a fan has a vital effect on its performance, longevity, and noise. There are different type of bearing to consider when shopping for the best 120mm case fan, which includes;

  • Ball bearings- can be installed in any direction, fairly silent, and have mid-range longevity.
  • Sleeve bearings-less expensive, fairly quiet, but they are not durable and can only be installed vertically.
  • Fluid bearings (FDB) & hydrodynamic bearings (HDB)-Great bearings used in high-end rigs. Comes with top-notch fan life expectancy, solid performance, and low noise.
  • Rifle bearings: very similar to ball bearings in terms of lifespan, installation, and noise levels.

Considering the above qualities, since when the fans age, most of them will get noisier over time, meaning that even if you buy an FDB type of fan, you will need to replace it long before it is due if the noise gets annoying.

2. Compatibility

To determine the best 120mm case fan compatibility, you need to pick out your motherboard and counter-check the secured pins. Since fans come with varying types of pins, you may need to check the adapter. It would be best to shop for the models that fit your build.

3. Noise level

The noise level of a fan is measured in dB(A). Most fans have noise levels ranging from 15 to 30 dB(A) category, meaning that the amount of noise they produce falls somewhere between a whisper or a quiet conversation to the sound of a dropping pin. Many factors come into consideration here, determining how noisy your fan is. Generally, when you are doing something taxing on your PC, the fan speeds may pick up and hence get louder. Also, fans get louder with overuse and age.

4. LED Vs. No LED?

When shopping for the best 120mm case fan, consider if you want a case fan with LED or no LED lighting. Colorful LED lighting is the trend nowadays, and many people are embracing them. There are different colors such as blue, green, red ( rainbow). RGB lighting allows these case fans to stand out are controllable. So, if your preference is pure red rather than an entire rainbow of colors, you can control the color mode with ease.

Furthermore, some case fans have a minimalistic style and may not be the candidates for the splash of color that these LED lighting fans offer. Nonetheless, even the plainest case fan makes for a great canvas that these fans then build upon.

5. RPM and cooling capacity

Since you are buying a case fan to keep your computer cool, it is important to consider the best PC cooling fans. Things like brands and looks play a second role in the sheer cooling power a fan can offer. Conversely, fan strengths are listed in cubic feet per minute (CFM) and revolutions per minute (RPM). CFM usually measures the airflow that a certain fan can commit, meaning how much it can cool in your case.

RPM usually measures how fast your fan rotates per minute. The thumb rule aims for high CFM with a moderate RPM. High RPM fans tend to be noisy at times. Nonetheless, louder fans are quiet enough not to be troublesome at all, thanks to modern technologies.

6. The lifespan of the fans

The lifespan of a case fan relates directly to the bearing type. A fan's life expectancy is also affected by how regular you use it and the temperatures it is forced to work with. Different types of fans usually vary in lifespans: you can expect a range of 30,000 and 300,000 hours, depending on your fan. When shopping, look for the fan that comes with a good lifespan.

7. Budget

Case fans come with different prices depending on the efficiency, size, bearing type, manufacturer, and additional effects like LED lighting. 120mm case fans are neither expensive nor cheap; however, even within that bracket, the prices vary. Furthermore, don't forget that you will need to buy more than one fan in most scenarios, meaning that the expense is double or more.

Saving some bucks by buying a cheaper model makes less of a deal than avoiding, for instance, replacing your GPU. Nonetheless, if you are looking to create a great PC, forego cheap fans. They are some of the essential components out there.
