Is your PC running hotter than its ideal temperature? For intense gaming, you should be looking for the best case fans that suit your PC’s temperature. Indispensable components such as the CPUs and processors in your PCs need to be kept at ambient temperature to prevent overheating, malfunctions and damage. Keeping this at its usual temperature helps you increase the lifespan of this components.  Your case fan is an active cooling tool that aids in your PC’s maintenance and with the right positioning you can keep your PC at the best temperature. In this roundup, the VG crew ranks the best 120mm case fans for your PC. Let's dive into some of the best case fans and why you should consider them.

Most Effective Case Fan: Noctua NF-F12

Noctua NF-F12 PWM, Premium Quiet Fan, 4-Pin (120mm, Brown)
  • Premium quiet fan, 120x120x25 mm, 12V, 4-pin PWM, max. 1500 RPM, max. 22.4 dB(A), >150,000 h MTTF
  • Award-winning 120x25mm fan with Focused Flow frame for high static pressure and superior quiet cooling performance
  • Ideal for CPU heatsinks (e.g. Noctua NH-U12(S) series) and water cooling radiators, perfect replacement fan for loud all-in-one (AIO) coolers
  • 4-pin PWM version for automatic speed control via 4-pin PWM fan headers, broad 300-1500rpm speed range (1200rpm max. with supplied Low-Noise Adaptor)
  • Includes anti-vibration mounts, fan screws, Low-Noise Adaptor, extension cable and y-cable for running two PWM fans on the same header

When it comes to effectiveness, then Noctua NF-F12 is the best for you on this list. With Noctua products, you typically don't get the flashiest fan in design and color. However, when it comes to effective work, it makes up for just about everything else. In truth, it is a bit of a stretch to find many negatives about this case fan, besides its color and design.

Perhaps, the most impressive feature is the less noise that it produces. This fan comes with a Low Noise Adapter (L.N.A) which reduces the fan speed from 1500 to 1200 RPM. The Low Noise Adapter can be used either to keep the fan’s speed at 1200RPM or cap it to the maximum speed with the automatic PWM control. This case fan comes with silicon anti-vibration pads installed in them, to ensure the only sound you hear when running is the motor. It sounds amazing, right? If you are all about the performance and care less for features like color and design, then the Noctua NF-F12 is about perfect for you.

How to Buy a Case Fan

The action of a computer is entirely similar to human behavior. Every human has a limit just like a computer. If you work 24 hours a day with no food or water, you will perform below standard because your body system will break down completely. A computer with an overheating CPU will perform poorly or possibly crash, and this may ruin your day. When you set out to buy a case fan that will suit your gaming PC, there are some important features you need to consider. Below are a few things to consider.


There different sizes ranging from 25mm – 250mm, but the common sizes are 80mm, 120mm and 140mm. You need to choose the size that works best for your gaming PC. If possible, choose a 140mm for a gaming PC because they provide your PC with the best active cooling system at lower RPMs.


Noisy fans can drive you insane. Your best option is to choose a case fan with less noise. If you are a vlogger then you want to choose a case fan with little or no noise. Remember that if you are operating an intensive gaming Pc, there will already be noise from your GPU, CPU and other parts. Reducing the noise of your fan can help keep the total noise down.


Airflow is the major reason you are buying a case fan. To ensure your PC is receiving the right amount of air, you should buy a case fan with maximum airflow.

Power Connector:

Case fans are connected to the motherboard of your PC. Your motherboard usually has 2 pins; the 4 pins connector fans have PWN function to keep the speed in check. The 3 pin fans come with tachometer functions that allow the fans RPM to read your PC’s motherboard.
