Pros

• High CFM, but low RPM
• 4-pin connector for manual control
• Very quiet; Comes with Low-noise adapter (LNA)
• Static fan

Cons

• Not recommended for larger cases

Noctua is a name you can trust when it comes to cooling solutions. With the Noctua NF-A8 80mm case fan, you get the best performance in the 80mm category.

The NF-A8 features a sophisticated aerodynamic design measure and advanced acoustic optimization (AAO) that’s responsible for keeping the noise level as low as possible. In fact, this runs a maximum of 2200 RPMs (with the 4-pin PWM setup) and still provides a mere 17.7 dBA noise level – pretty impressive!

Another contributing factor to this very silent fan is the SSO2 (self-stabilizing oil-pressure bearing version 2) that Noctua has implemented in this fan. They claim it offers higher precision and better longevity than conventional bearings.

The 4 vibration compensator rubber fan screws also contribute to its silent profile. This comes with a sleeved 4-pin-Y 30cm extension cable should you wish to have full control over the speeds. Being a static fan makes it perfect for promoting airflow in tight areas.

On the other hand, it also comes with a Low-noise adaptor (LNA), but only use this if you are going to make manual adjustments and keep in mind that this will limit the RPM of the fan to only 1750 RPM.

Pros

• Very quiet
• 4-pin controller for manual fan control
• Affordable for a 200mm fan
• RoHS compliant

Cons

• Needs a third party software to turn lights off

The Cooler Master MegaFlow 200 is one of the best fans in its respective category.

It may run the conventional sleeve-bearing model but it also makes up by being the most efficient and the most affordable. For the price, you have a 200mm fan that delivers a whopping 110 CFM to keep your system cool round the clock. Plus, you won’t even need to ramp up the RPMs to over a thousand to reach this because it gets there even at 700 RPM.

While it’s the biggest fan on our list, it’s still fairly silent (19 dBA) and almost as silent as the Noctua NF-A8 (17.7 dBA). Unfortunately, the color themes are fairly limited, only offering black, red, and blue versions. Furthermore, Cooler Master has used environmentally friendly materials in the making of this fan, meaning it is fully ROHS compliant.

Pros

• Very quiet; it’s almost non-existent
• Also great as a radiator fan

Cons

• Only available in black (non-LED)

The Cooler Master Silencio FP 120 PWM really lives up to its name: Silencio.

At first, you’d mistake this as a standard 120mm fan but if you look closely, this black case fan has a very distinct sickle-looking blade. This is what makes the fan operate silently at high pressure.

On top of using a Loop Dynamic Bearing (LDB), this also uses the Silent Driver IC technology which provides a smoother spin and less torque impulse for minimal vibrations and ultra-low noise.

Even though you can manually control the fans via a 3rd party software like SpeedFan (thanks to the 4-pin connector), you won’t necessarily have to in order to keep noise levels down. Other contributing factors that make this fan silent are the 4 metal screws and 4 anti-vibration rubber screws that it comes with. A great silent pick!

Things to consider when shopping for the best PC case fans

You need to consider the following factors when buying the best PC case fans to ensure they will not only fit inside your system but also keep it sufficiently cool as well.

So, let’s jump into the most important things to consider when looking at the best-case fans of 2022.

Static pressure fans or airflow fans?

The first thing you have to consider is whether you’re better off getting a fan with high static pressure or a fan with high airflow. This is determined by the actual shape of the fan blades. Yes, that’s right. You can get the same shape and model of a fan, only with different fan blades.

You don’t need to go through the spec sheet to tell if the fan is either a Static Pressure or an Airflow type. Simply look at the fan face and look at the distance between the fan blades. If the spacing between the blades is small, it’s a Static Pressure type. If the distance is large enough for your index finger to go through, it’s an Airflow-type fan.

Airflow fans

These work best if there are no restrictions in front or behind the fan. For instance, if you have a case that has plenty of open space, these fans should give your case a more efficient airflow.

Static pressure fans

Static pressure fans disperse air more evenly. This means they are not as powerful in a direct line, but that they can do a good job when there are obstructions such as components and radiators.

CFM meaning (cubic feet per minute)

So, what is CFM? Well, a fan’s airflow is measured in CFM or cubic feet per minute. This determines the volume of air the fan can cycle through in a minute. Generally, the higher the CFM rating, the better. However, when dealing with hardware obstructions, static pressure can be more efficient with less CFM.

The ideal CFM for a PC can change on a case to case basis because there are a lot of factors that need to be considered. Factors such as case size, design, the amount of heat your CPU pumps out, the type of CPU cooler you have, the GPU fans (whether it’s an open-air or a blower type), and the number of case fans you can install.

Size (mm)

Why would you want larger fans? Well, it is pretty basic: they literally move more air. In case you’re not sure which size fits your case, simply check your case manual. You can also visit the manufacturer’s website to see the dimensions and specs of your case. And if all else fails, simply grab a measuring tape and measure the fan inside your case. Below are some of the most common fan sizes along with the distance between their screw holes:

Speed (RPMs)

A fan’s speed is measured in RPM (Revolutions Per Minute). The higher the RPM, the more air is pulled into the system. RPMs have a direct effect on a fan’s noise level because the faster it spins, the more noise it produces. This might also affect the size of the fan you want. While you might be able to use a small fan at a fast speed, it will likely be louder. So, instead, you can use a larger fan at a slower speed. To get the right RPM for your setup, simply set the fans at max speeds using a 3rd party software like SpeedFan and drop the speed by 25% until the fan isn’t too loud and temperatures are acceptably cool.

Bearing type

There are three basic bearing types used in most case fans today and they are as follows:

• Sleeve Bearing
• Double Ball Bearing
• Fluid Dynamic Bearing and Hydrodynamic Bearing
• Magnetic Levitation

Sleeve bearing

This type of bearing is the cheapest and is expected to last around 40,000 hours of usage run at 60°C (140°F). The fan speed is designed to be low-maintenance and have low operating noise. These types of fans are recommended to be mounted vertically, which is said to be quieter. However, it should be noted that these tend to break down without any warning despite having low operating noise.

Double ball bearing

The double ball bearing is more expensive than sleeve bearings, but they do last longer; up to 60,000 to 75,000 hours run at 60°C (140°F). Unlike sleeve bearings, these can be mounted in any position and are also louder. This is why it’s not recommended for home usage, but is perfect for server farms.

Fluid dynamic bearing and hydrodynamic bearing

These are the premium bearings. They tend to last the longest, reaching up to 100,000 to 300,000 hours of usage run at 60°C (140°F). Like the double ball bearing, they can be fitted in any position. They also have the lowest noise levels of the three and are fit for both server and home usage – though they are preferred mostly for home use since they are a little more pricey.

Magnetic levitation bearings

One of the bigger innovations and good choices for the best PC fans is the use of magnetic levitation. Featured in the Corasir ML range, the bearings use magnets instead. This cuts down the friction and so you get a much lower noise at higher RPMs.

Noise (dBA)

Fan noise is measured in A-weighted decibels (dBA). A-weighted decibels are a way we can measure how loud a sound is to the human ear. Almost all case fan manufacturers include the noise level of the fan.

Some factors that contribute to fan noise includes:

• Type of bearing used
• The distance of the blades from one another and the outer ring
• How the blades are designed
• How fast the blades spin (Speed/ RPMs)

Generally, it ranges anywhere between 10dBA to 36dBA. Regardless, you’ll want a case fan with the least amount of noise for obvious reasons. Here is a scale of how loud these noises are compared to everyday sounds:

Power Connectors

There are three types of fan power connectors:

• 4-pin connectors let you control the fan on-the-fly using a third party software like SpeedFan.
• 3-pin connectors can only be adjusted by altering the voltage in the BIOS. But not all motherboards support this feature.

Running the 3-pin connectors at a low voltage may lead to problems or may not run the fan at all. So make sure you know exactly what you’re doing when doing this.

• MOLEX connectors will run at full speed at all times and cannot be adjusted in any way.

Connector types affect compatibility so check your motherboard’s connector type before purchasing.

Aesthetics

Case fans can be customised to improve how your PC looks with either colour rings or RGB lighting. When it comes to fans we tend to place more priority on function as these will help the longevity of your system’s lifespan.

Intake/Exhaust

When installing fans into your case, you will need to choose whether each fan is going to be an intake or exhaust fan. Ideally, you want to make sure you have at least one intake and one exhaust but don’t worry about the ratio too much.

Some terms to be familiar with are:

• Neutral air pressure – Equal amount of air goes in and out of the case. You will technically never reach a perfect state of equilibrium, but you can get close.
• Positive air pressure – Fans pull more air into the case. This can cause air to be brought in through smaller holes that don’t have filters or fans. This means that you will get dust deposits in unpredicted places.
• Negative air pressure – Fans push more air out from the case, creating a vacuum.

Obviously, you’d want to have neutral air pressure, and a good way to accurately get this right is by measuring the total CFM of all intake fans and CFM of all the exhaust fans. You get a positive air pressure if the intake CFM is greater and negative if the exhaust is greater. An equal number of CFM means you have roughly neutral air pressure. Do note, that if a fan is obstructed, then it will not be netting its max CFM.

It’s also worth noting that fan placement can be tricky to get down. So it can be best to pay attention to where the majority of your dust builds up. If you feel it’s causing problems, then you can adjust your fan placement accordingly. If you aren’t sure whether your fans are blowing in or out, then the next section will help you with that.

What size is the best?

The size of a PC case fan (80mm, 120mm, or 140mm) can affect its performance and noise levels. In general, larger fans (120mm and 140mm) tend to move more air at a lower RPM, which can result in lower noise levels compared to smaller fans (80mm). These larger fans also tend to have a longer lifespan as they are less likely to wear out quickly.

However, 80mm fans can also be useful for specific situations, for example, when space inside the case is limited and a larger fan cannot be installed. Ultimately, the choice between 80mm, 120mm, or 140mm fans will depend on the specific needs and preferences of the user. Factors such as noise levels, cooling performance, and the overall size of the case should be taken into consideration when making a decision.

Final Word

There you have it, the best PC case fans for your PC build. We have made sure to include several different options to cover quite a wide variety of different consumer needs. Each fan has been tried and tested with several different case options to ensure we recommend the very best when it comes to case fans.

If you’re going to need a 140mm fan that doesn’t just promise performance but also does so silently, nothing can compete with the Noctua NF-A14. This is easily one of the best PC case fans on the market. In the 120mm territory, the Thermaltake Riing Quad fan pack is an RGB option that would look brilliant inside any tempered glass case. It’s a high-performance fan with relatively low noise levels and does a good job of increasing the aesthetic appeal of your build.

We personally recommend the Noctua NF-A8 PWM case fan if you have a case that requires an 80mm fan – Thermaltake Core V1. It delivers an astonishing amount of CFM without being too loud.

FAQs

What brand makes the best case fans?

One of the best choices renowned by the community is Noctua. Who is praised for their great quality products, top performance, and leading support even with the higher cost or unconventional color schemes. Noctua is well-known and recommended by many in the PC community and so is a great choice if you’re not after anything colorful.

Which fans should I use for my PC?

When it comes to picking out which fans to use in your PC then there is a range of choices to pick from and decide on. Firstly you need to know the size to include, in most modern cases, 120mm and 140mm are the most common. As such you need to know how many and what ones to include in your case. If you have space 140mm is better to utilize the space and give more airflow, but will usually cost more.

Whilst the design is also important depending on how it fits the build. As you may want an RGB choice of the build so that might be important or if you have a white case, white fans will be good to match. Whilst performance and function also matter, if you want a more silent performing fan then those are more important.
