Things You Should Know About a PC Case Fan

Choosing the right fan for your system is quite important for cooling for system noise and for the looks.

We break down all the important terminologies and briefly describe the importance when it comes to the specification of fans what to look out for depending on your situation.

Size

The first quick specification is the size and that is the measurement of the frame in millimeters not of the blades. Comes in the range from really tiny 25 mm of fans all the way up to 230 mm of fans.  With 120-mm and 140-mm sizes being the most commonly used on cases and coolers while the default thickness of the fan is 25 millimeters which is perfectly fine for the majority of situations. 

But be mindful there are really low-profile fans that exist for particular small form-factor cabinets where 120mm or 140mm fans will not fit. And just be mindful that all specifications on the box are measured at the maximum RPM of that particular fan.

Fan Airflow (CFM – Cubic Feet Per Minute)

Another factor that you should keep an eye on is airflow, which is one most important spec usually measured in CFM that stands for cubic feet per minute, and sometimes you also see measurement in cubic meters per hour in different regions

Obviously, the higher the number the more air the fan can move. 

Confused enough what figure out what CFM is and what does it do? so, let’s use a fun example with the Dark Base Pro 900 pc case, that’s volume is approximately 2.89 cubic feet. This means that if your fan has 59.5 CFM can replace the entire volume of air inside the case 20 times in one minute or every 3 seconds.

Now imagine you have three of those fans set up for exhaust at full RPM without any restriction whatsoever that means you’re tripling the CFM amount and you’re placing the entire volume of air inside that enclosure per second which is crazy right? 

Caution Alert:

We want to clarify that these maximum CFM and static pressure values cannot be reached in a confined space like a computer case because they only apply to an ideal environment with no obstruction there. Also, if the case was letting air through without resistance at all so treat these specs as general guidelines.

The CFM (Cubic Feet Per Minute)

CFM spec is based on the blade design and the frame design. But more importantly, it is based on the speed of the fan measured in RPM. 

A bigger fan will always move more air at the same speed as a smaller fan. So, 2x 140 mm fans are about the same total CFM as 3x 120mm fans. 

PWM Control

Let’s be real, most of us are not running full speed on all fans at all times which is why PWM control is so important with today’s fans. 

PWM stands for pulse width modulation and that is indicated by a four-pin connector instead of a three-pin connector.

Pro Tip:

When you plug a PWM fan into a four-pin PWM fan header on your motherboard you can do all types of cool stuff. Like, full precise control of the RPM range, you can set the RPM to reflect on hardware temperatures and like spike up to 100% RPM when CPU load is high or something like that and you can also do really low RPM with PWM for really silent almost inaudible operations.

The sad part is, for three-pin fans precise RPM control is not possible but some other boards allow for voltage control for three-pin fan headers like 5, 7, or 12 volts. 
But the good part is, you can also get voltage-reducing adapters to reduce the fan speed from its constantly running at 12 volts which is a 100% load to something lower.

Blade Design

What happens when we have airflow resistance from CPU towers, radiators, or case elements?

Static pressure or air pressure is super important to talk about. It is measured in millimeters of water or millimeter of water gauge or millimeter of water column or Pascal, depending on the brand.

The higher the static pressure the better the fan can force air through whatever resistance is on either side and the fan. So, blade design is crucial for this, which is why they’re much wider than your airflow fans but so is the RPM. 

Some industrial versions of fans deliver insane amount of static pressure but at crazy high speeds and of course noise levels.

Fan Noise Level

Another important factor to consider, here is the noise level measured in decibels. 

According to our experience, anything around 20 and lower DBA is basically inaudible even when you combine multiple fans for a really quiet system. We’ve done testing with a few of those and they’ve been really satisfying and just like turning things on and things are spinning but you can’t hear anything but the temperatures are still fine that’s a good feeling

Fan Bearing

Finally bearing type also has an important part to play in a noise profile but also the longevity of a fan. 

Some brands specified the lifespan in hours ranging from 40,000 to 50,000 to 80,000 hours with rifle bearing, over 150,000 hours with UFB, and 300,000 hours with fluid dynamic bearing. These hours are around 34 years of continuous operation that is what the bearing is rated at, which is kind of insane

Bottom Line:

Hopefully, this gives you a good baseline of understanding all these specifications when it comes to fans and helps you choose the right thing for the job. You should understand that there must exist a good balance between noise levels and RPM.

  • Available in LED version, adding cooling aesthetics to your chassis

Review:

The Pure 20 by Thermaltake is a very unique fan it’s large available only in the 200-millimeter format but it’s still an elegant fan performance-wise it’s outstanding.

it’ll do absolute wonders for the airflow inside your case but it is a bit noisier than the competition standing at 28 decibels. 

The main takeaway here is that the pure 20 doesn’t sacrifice any performance for the sake of convenience. It is all about power, if you need a case that prioritizes power over everything else, you’ll find few models as cost-effective as a pure 20 but if not, there are less noisy and more customizable options out there.

Speaking of which, gorgeous as it is; this fan is only available in two versions one a simple matte-black the other a transparent one with blue LED lighting.

And if you like what the Thermaltake has to offer but don’t want it in a 200-millimeter fan then you’ll love the Thermaltake Ring 12 because it has it all it’s fast, quiet, stylish, and affordable what more could you want?

It has the same incredible speed-to-noise ratio that we loved in the LL 120 that’s 1500 rotations per minute with the 24-decibel noise level and while it may not be RGB the ring fan still looks phenomenal even with just the LED lighting.

And more importantly, you’ve got enough colors to choose from to fit any build blue, red, white, yellow, green, and orange.

It comes in both 120 millimeter and 140-millimeter sizes allowing for greater compatibility and it uses the hydraulic bearing whereas the pure 20 fan uses sleep bearing

The only thing that could be construed as a fault is the set’s lack of RGB lighting but given that Ring 12 costs less than half as much as the LL 120 we wouldn’t really say that’s the case it is absolutely flawless.

Thermaltake Pro 20 Product Review

Why You Should Buy

  • The fans are nice and bright and give great airflow
  • Easy to set up
  • ARGB works great with aura-sync and fans are quiet

Why You Should Avoid

  • Cables are really thick
  • Fans use proprietary connections, so no way to use them with a motherboard or another fan hub

7. NZXT FN V2

NZXT FN V2

  • The redesigned fan blades have been made thicker to give more reliable operation and longevity.
  • Both the 120mm and 140mm have been tuned to peak at just 21 dBA at full speed.

Review:

and finally, the time has come to close off this list with the NZXT FN V2 

NZXT is still a lesser-known manufacturer but their products don’t falter behind the competition at all.

They’ve got a rather unique look, very contrast like in this case, with black and white. We usually like their designs but we aren’t too keen on this one just because the white fan is going to stand out in some cases and not in a good way.

Unfortunately, there are no other color options but once you hear what its strengths are you may decide not to mind 

So, what are those strengths? Honestly, everything except the color scheme the FN V2 is very well built, it uses rifle bearing, it’s quiet and efficient with 1200 RPM and 21-decibel noise level and it’s remarkably cheap like single-digit cheap two of these fans together cost about as much as most other fans in this article.

Let us tell you that this fan only comes in 120 millimeter and 140-millimeter sizes.

nzxt v2 Prodcut Review

What We Like

  • Very quiet operation while moving a considerable amount of air
  • The plastic feels solid. Not too thin and not too thick
  • The wire is nice and long, giving you routing options. It’s braided which is also good.

What We Don’t Like

  • No PWM

Different PC Case Fan Sizes: All You Need to Know

80 mm (3.1 inches) Fans:

These cases are generally used to cool CPU heatsinks. Usually comes with a speed of 5000 to 7000 RPM but creates a lot of noise. You may have seen 80mm fans in various GPUs. Thus, due to their small size, these are super-efficient to use in mini ITX cases or even in SFF.

120 mm (4.7 inches) Fans:

It is one of the most commonly used size fans for air cooling of the pc case. These replaced the odd size of 92mm fans with their efficiency and acceptability. You can use 120mm fans in any form factor easily whether it’s mid-tower or mini-tower or even builders use it in full tower pc cases as well. These fans rotate at approximately 3000 RMP, producing ample airflow without producing much noise.

140 mm (5.5 inches) Fans:

This fan size is the second most accepted in the user community as it is mountable in most pc cases nowadays. It could be a bit heavy on your pocket as compared to 120mm ones but thanks to its static pressure, it’s recommended for high-end pc build because it keeps your pc cool without making any noticeable noise. You can use 140mm fans in mid-tower and full-tower pc cases, even with larger liquid-cooled variants.

200 mm (7.9 inches) Fans:

The simple logic of these fans is that they rotate on low RPM, almost on 800 RMP on average and due to their large size, they keep the operations quiet yet create a powerful airflow. You can easily use these fans in the full tower (E-ITX) or in specialized ITX cases.

Bottom Line

There are also other sizes available in the market, including 92 mm fans and 180 mm but those are not common or generally used anymore. But the most common sizes of case fans are 120mm and 140mm because of their compatibility and performance and can fit in almost all pc cases.

120mm vs 140mm: Which One Is Better?

If you have a choice between using a 120-millimeter fan or a 140-millimeter fan you should always go for the 140mm fan as most computer cases these days have mounting points where you can fit either a 120 or 140 fan.

Luckily, we tested all the fans in the exact same way so they can be compared against each other to finally figure out what’s better 

As a result, we can see the average 140mm fan definitely performing better than the average 120mm fan. We came to this conclusion after testing on the following specs;

RPM

Things get a lot closer at higher fan speeds but the 140 mm still does perform slightly better.

Noise Level

Noise levels were almost identical between the two.

Heat Sink Performance

Here we saw a much larger difference with the 140mm fans outperforming the 120mm fans by almost 10 degrees of some noise levels at high speeds. Though things get really interesting with the 140mm fans producing much higher noise levels without much drop in temperature. This may just be due to having some higher noise fans in our 140mm fan group.

Radiator Performance

We saw a very similar situation here to the heatsink, with 140mm fans performing much better on average although they do get very loud at high speeds. 

But still looking at the averages, we can say case closed right 140mm fans are clearly better.
