5 Best RGB Case Fans In 2021

Fans are an integral part of our PC builds. They keep the hot air circulating and cool down the hardware. One problem is that every fan has a different color which can be distracting for some people. Also, if you have two fans on one side of your case, they will create a rainbow effect when in use because colors mix together in the light spectrum.

The solution to this issue is RGB fans. These lights come in all types of colors including red, green, blue, and white so you can customize your build according to your preference or moods! There are a lot of RGB case fans out there, but not all best RGB case fans are created equally.

This blog post will be going over some of the best RGB case fans on the market and what makes them so great. Keep reading to find out more. It may be hard to believe, but we live in a world where RGB case fans exist. We all know that they’re aesthetically pleasing and add some flare to your desk, but what else do they offer?

In today’s blog post I’m going to show you why these case fans are worth buying and when you should buy them. Aesthetics aside, the main difference between regular LED vs RGB is control and customization.

You can customize almost every aspect of your fan with software like ASUS Aura Sync which gives you the ability to change colors on an individual basis (if desired).

You can also set different profiles for different games or programs which will automatically change the color of your system based on what is running at any given time.I have had a lot of trouble finding case fans that are compatible with my motherboard, especially RGB ones.

Noctua NF-S12B redux-1200

Best Pick

When I first built my computer, I used the NF-S12B redux-1200 fans to cool my overclocked CPU. Now that I have upgraded to an i7 chip, these fans are not giving me enough cooling power. My fan was making a lot of noise and it wasn’t performing like it should be.

Other than replacing the fan for another Noctua product (the NF-A14), there is nothing else you can do with the case/fan combo. Before buying this new one though, make sure your motherboard has an open 4 pin connector or else you won’t get any speed control on this new fan.

Noctua is a company that is known for its high-quality cooling components. The Noctua NF-S12B redux-1200 PWM 120mm fan is one of the best they have to offer. It has a maximum speed of 1200 RPM and comes with a low noise adaptor, allowing you to fine-tune your performance needs as well as set it up in different ways depending on your preference.

For those who are not familiar with how fans work, here’s some information about what makes this model so great. The Noctua NF-S12B redux-1200 is the newest edition to their fan series.

The new design focuses on airflow and noise reduction, making it a perfect fit for those of us that want our components cooled without having to sacrifice anything else. With this little guy, you can be sure your PC will stay cool and silent all day long. I’m the Noctua NF-S12B redux-1200.

I have many features that will make your life easier, including a low-profile design so you can fit me in tight spaces. But my best feature is my noise reduction technology! With me, you’ll be able to enjoy your favorite music without any distractions from fans or other components.


  • Inexpensive but performs great
  • Less ugly than the old Noctua models


  • No RGB
  • Not the quietest Noctua fan

Staff Pick

The Corsair LL120 RGB 120mm Dual Light Loop PWM fan is a great choice for any case that has space to show off. This fan features 16 independent LED lights which can be customized using Corsair’s iCUE software.

The lighting effects are very high quality and give your PC an awesome look when it comes time to game or just watch videos at night! This kit includes the two fans, two light strips, and USB cable that allows you to control the color of each individual light up strip.

In addition to that, it has been made compatible with standard 4 pin PWM motherboard headers as well as USB 2.0 connections for additional control over its speed settings through Corsair Link Dashboard software. When used together with other compatible devices

Noctua NF-A12x25 PWM

The Noctua NF-A12x25 PWM is a low-profile fan that can be used with standard 120mm mounting holes or in areas where space is limited. It has an airflow of 50.6 m3/h and produces only 24 dB(A) at maximum speed.

The frame consists of nine blades, which are slightly curved to ensure optimal airflow when the fan spins at higher speeds. This makes it ideal for liquid cooling systems where noise levels must be kept to a minimum while still providing sufficient cooling power.

When you have this much technology packed into one small package, you’ll wonder how you ever lived without it! The Noctua NF-A12x25 PWM is a new 120mm fan that was designed to provide the best cooling performance in its class.

This allows for more airflow at lower noise levels than has ever before been possible with this size fan. With all these improvements, it’s sure to be your next favorite PC cooling fan! I have been a fan of Noctua fans for years, but I had never seen one with such an unusual design.

The NF-A12x25 PWM is the only 120mm fan in their lineup that has a 25 mm thickness and it weighs just over 7 ounces. It’s designed to be installed in front of a very large heatsink or radiator in order to maximize airflow and pressure at lower RPMs. This review will explore the features, specifications, and performance of this unique fan from Noctua.


  • Highest airflow of any fan we tested
  • Lots of accessories included


  • The styling isn’t to everyone’s taste
