The Best Case Fans in 2021

Best case fans

If you’ve noticed that your PC is running a bit hotter than what is ideal for your system components, it may be time to start checking out some of the best case fans in order to avoid future problems. There are a broad variety of options available to you when it comes to case fans and it is important to choose the right one for your case.

To help you out a bit, we’ve put together this guide to explain how a fan cooling system works and how to pick the best one for your case and components.

Before you start shopping, you’ll want to double check the dimensions of your case and how much clearance you actually have internally for a fan setup. In some cases, you may be better off with a multiple fan system, rather than just a single fan. Really, it all depends on what you’re trying to accomplish.

What Role Does a Case Fan Play in Maintaining PC Performance?

As the technology driving our PC’s and laptops continue to increase in both power consumption and speed, so do our computer’s internal temperatures. If important components such as the CPU and PSU are not kept at ambient temperature via passive cooling, you desperately need a case fan or two in order to help carry the excess heat load. Left unresolved, excess heat will severely shorten the lifespan of your PC components.

Active cooling has become an integral part of PC maintenance. That’s where case fans come into play. With proper positioning, your case fans will simultaneously push hot air away from problem areas such as the CPU heatsink and pull fresh, cool air across them.

How to Choose the Very Best Case Fan for Your PC

A fair amount of thought and research should go into the purchase of a new case fan for your PC. You’ll want to consider things like;

  • Whether or not aesthetics are important. Does your case provide a view of your fans? Does it matter to you what it looks like? There are fans with cool lighting effects for computer enthusiasts looking for something a bit more unique.
  • What your primary goals are for active cooling. Do you have specific problem areas that are in need of active cooling, or are you taking preemptive measures to protect the entire system? Are you in the market for a new fan because of heat problems, noise levels during operation, or both?
  • How much noise you want to put up with. Noise complaints are most common amongst overclockers, gamers, and professionals that need a lot of processing power. There are, however, some really nice, quiet models available if you’re willing to pay a bit extra. To better understand fan noise rankings, check out this guide.
  • How you want to control your fan. Do you want a simple, plug-and-play fan that turns on and off as necessary? If you’re interested in manually controlling your fan settings, picking up a fan controller for your system might be a good idea too. You can also use software to control your fans.

Before you go shopping, you’ll need to check a few things:

  • Check your PC’s connector type. There are 3 different types of connector, a 2-Pin, 3-Pin, and 4-Pin. A 2-Pin is a simple, on/off setup; not commonly used in modern computing. Both the 3 and 4-Pin connectors allow more control over fan operations, leading to more efficient active cooling.
  • Choose an appropriate fan for your case size. If you have an extra-large case, you’ll want to consider a 200MM case fan, for instance. In this situation, an 80MM fan would do very little to cool your system, as it lacks the force of air flow and RPMs necessary to efficiently move cool air to important areas such as the CPU.

Another Favorite 80MM Case Fan

ARCTIC’s Fluid Dynamic 80MM Case Fan is probably the best budget case fan available to consumers today. Its two-way installation allows you to blow warm air out of your case or pull cool air into your case; which is highly effective as a cooling measure. With a 4-Pin connector, this affordable case fan is ready to plug-and-play, set up with a fan controller, or even directly control your fan’s PWM with software settings.

Another great feature of this ARCTIC case fan is the fluid dynamic bearing, which has an integrated capsule of lubricating oil to ensure that operation remains smooth and silent even at high speeds. Other quiet models typically rely on a sleeve bearing to achieve this level of quiet, however, their service life is usually much shorter than that of fluid dynamic bearings.

  • 4-Pin connector that works with software and fan controllers to control WPM
  • Very quiet model
  • Highly affordable
  • Small enough to fit in smaller cases
  • Easy installation
  • Too small for medium-large cases

The Best 120MM Case Fan for the Price

arctic f12 pwm rev 2 - Best 120MM Case Fan for the Price
The F12 PWM Rev. 2 Case Fan is another great model designed by ARCTIC; one of the leaders in the industry of case fans and general cooling technology. This 120MM fan is a 4-Pin connector model, which allows you to control the pulse width modification of your fan. This is useful for heavy duty computer users such as gamers and designers who are battling unusually high operational temperatures.

Another benefit of the 4-Pin connector is that allowing your motherboard to control the fan’s PWM will dramatically cut fan noise levels. Constant monitoring of exact temperatures allows the system to appropriately estimate how much power and running time it will take to keep components at ideal temperatures. That means that the fan can avoid running at max power, and thus avoid running at max noise volume.

  • 2 Way installation so you can push or pull air
  • 4-Pin connector allows control of PWM
  • Not enough air flow for larger cases
  • May not fit smaller cases

Corsair ML140

A Revolutionary Fan that Doesn’t Bring Anything Revolutionary

corsair ml140
Corsair ML140, where ML stands for Magnetic Levitation, is a product that introduces a new technology to the industry, and its primary goal is to reduce the noise levels. Built to last, with a custom rotor design and a PWM control, this fan delivers a high airflow and achieves speeds from 400RPM to 2000RPM. Unfortunately, its noise levels aren’t that good. Even though its performance is very silent at low speeds, it becomes louder as its fan speed increases.

Generally very stylish, with a decent five-year warranty, this fan presents a quality product, with a decent price and overall a good performance.

Although Corsair ML140 is bringing something completely new to the fan market, the fact is that the involvement of a Magnetic Levitation technology actually doesn’t bring any noticeable benefit to the fans performance. Hopefully it will bring something in the future, but for now, this is just a decent product, which is, on the other hand, more than enough in most cases.

  • Cool lighting
  • Almost silent at low speeds
  • Loud at high speeds

A Perfect Combination of Good Performance and Attractiveness

corsair ql140 rgb
Corsair QL140 RGB is a very well-built fan, with an excellent balance of performance and good looks, as well as a nice set of customization options that might play a major role for RGB fans.

Great things usually aren’t cheap and Corsair QL140 RGB is no exception to this rule. However, it offers a fairly good value for its price, such as fan speed of up to 1250rpm, good 50.2 CFM airflow, and equally importantlz, low noise performance.

NZXT AER RGB 2 – 140mm

An Excellent Fan that is Worth the Money

nzxt aer rgb 2 - 140mm
If you are looking for some serious PC customization hardware that will not be there only for the sake of appearance, but also with a quality performance, NZXT AER RGB 2 – 140mm is the right product for you. With this fan, you will get a highly efficient cooling tool that is whisper-quiet and eye-appealing at the same time.

Thanks to its CAM-software, you will be able to easily configure and set your lighting effects, with an unlimited number of possible color combinations. Unfortunately, although the CAM-software is easy to use, sometimes it can be intrusive and annoying. Therefore, before the possible purchase, be aware of that, along with the fact that the fans have the RGB light only on one side, so if you don’t have a tempered glass side panel, you will have trouble enjoying their awesome looks in the first place.

Luckily, those are the only downsides of this otherwise excellent 140mm PWM static pressure fan that can bring a little bit of special touch to any gaming rig.

  • Quiet
  • Quality cooling performance
  • One-sided RGB LEDs
