Maximum Performance: Best Case Fans For Gaming PCs

Also called a system fan,  a case fan is typically mounted to the front or back of the computer case. The purpose of the case fan is to draw cooler air into the system from outside the case, move air along a heat sink for targeted cooling, and simultaneously blowing the hot air out of the case.

As a gamer, you know the sound of an overheating PC all too well. That tell-tale sign of an overworked fan.

While your computer came with a stock case fan, you may be considering an upgrade to give you the best possible air-cooled system for speed, performance, and reliability. And we can help you outfit your gaming PC with one of the best case fans for cooling and airflow on your PC build.

What to Consider Before Buying Case Fans

The right case fan will protect your computer components, preventing heat build-up and moving the heat away and out of the case.

If the heat is captured in the case for too long without an outlet or circulation, the extreme heat can cause component failure, overheating, and it can also severely compromise the lifespan of the computer part.

Some of the more common reasons you may be looking to upgrade your case fans is because:

  • You’re in the process of upgrading your PC
  • Your computer is not performing to spec
  • Your PC is generating a lot of heat.
  • You’re overclocking.
  • You want to tap into the extra fan features

Based on the key reasoning behind your case-fan upgrade, look at the relevant variables: size, power, cosmetics, air flow, and noise to determine the appropriate case fan.


The two types of computer case fans are axial and centrifugal. They are powered and controlled via 3-pin and 4-pin connectors.


The range of sized is between 25mm and 250 mm. More common sizes really range in the middle 80mm, 120mm, and 140mm.

You’re not just looking for the biggest fan, though. You also need to be sure that the fan is the appropriate size for the case.

You can find that information by reviewing the manual for your computer case. You’ll probably find a diagram and/or detailed specifics.

If you don’t have the manual easily accessible, you can usually find the information on the manufacturer’s website.


Fans are powered by 12 volts supplied by the power supply the motherboard. The small Molex connector fans are designed to run off the motherboard with 2 pins.

Fans with a tachometer signal often have 3 pins, so the motherboard can read the fan’s RPM. Fans can also come with a PWM signal that allows speed control and typically come with 4 pins.

Although the 4-pin fans can be more expensive, they are also popular because they can help you control and reduce noise.

While function is key to any case-fan decision, the aesthetics are often an important factor. With such a range of options for cases, the look of the fan(s) can make a big difference.

Even if you can see the fan while the computer is running, and even if aesthetics are super important to you, you should still put the performance of your machine above the coolness factor of flashing lights and a cool design.

The other reality is that the purposeful aesthetics feature may be adding a considerable cost differential. If you’re more for a cool-looking case fan that’s subpar in performance, it’s just not worth it.

You can still find case fans that still look cool, perform to the specifications you need, and will hopefully fit into your preferred price range.

Air Flow

The air flow is determined by cubic feet per minute (CFM), with the bigger number meaning that the fan is more effective at pushing air through the system.


The fan noise is measured in decibels (dB or dBA), and the typical range is from 10 dB to 36 dB.

The noise factor is not a deal-breaker for everyone, but it is a factor you can control, so it’s important to know that the noise can be directly related to the fan design, the proximity of the blades to each other, and the type of bearings.
