Things to know Before Buying a 50mm and 70mm case fan

You need to know the following things before buying a 50mm and 70 mm case fan:

  • 50mm and 70 mm case fans sized 50x50mm (length, breadth) but their thickness varies. Mostly their thickness is 10mm-25mm. So, be sure to check their specs perfectly before buying one or else your Fan might not fit where you have decided it to place.
  • Mostly every 50mm and 70mm fan require 12v to run properly. But there are fans which need higher voltage too.
  • Some of the 50mm and 70mm connect with 2pin and some with 3pin. That’s why I’m telling you to go through the specs carefully before you buy one.
  • Each fan creates a definite noise level. So, it’s your personal preference if you want a quite fan or not.
  • The bearing types of these fans are different (more on that later). So, be sure to choose the most suitable one for you.

5 Best 50mm Case Fans and Their Reviews

50mm Fans are the Fans that has lenth and breadth of 50mm x 50mm.

I have made this list after using each of them for making the best silent and cool raspberry pi 3 PC for myself.

Here are the Best 50mm Case Fans with their review:

1. EVERCOOL Brushless 50mm Fan


The EVERCOOL Brushless 50mm Fan is a really good quality fan.

I have kept it in the top as it has the highest Fan speed which is around 6000RPM.

This fan has a dual ball bearing to make it last longer than other ones. The cooling of this fan is more than efficient for its higher speed.

Yes, the noise level is a little too high near to 30dBA but buying this fan is worth the price for getting such higher fan speed.

But the good thing is:

The connecting wire is 7 inches. So, there won’t be any problem with connecting the fan to your PC.

You can also connect this fan with a molex connector as it comes along with the fan packaging.

2. GDSTIME 50mm Fan


GDSTIME 50mm Fan is a 5volt fan with a speed of 4500RPM.

This fan is mainly used for mini computers. It’s very suitable for the Raspberry pi 2 and 3.

Upside of this fan is, the noise level of this fan is not too high as it’s only 25dBA.

One thing to note that:

This fan uses a 2-pin connector and the length of the connecting wire is only 20cm. So, make sure you can adjust it with that wire or not by measuring your gear.

But the good thing is:

This fan comes with a good quality sleeve bearing and that’s I recommend it for long time use.

There’s another version of this fan which has a speed limit of 5000RPM which is insane.

But it will a require 12v source. Noise level in this version is almost the same as that of the 5volt one.

3. Fractal Design Silent Series R3 50mm Fan


If you ask me to describe this fan in one sentence, then I will tell:

This is the most silent fan in this list.

Yes, you have heard it right. The noise level of this fan is only 19dBA.

But you have to sacrifice the fan speed for this reason. This fan only has a speed limit of 3500RPM.

Other features are good including the design.

The Rifle bearing provides a hardcore performance by giving a static pressure of 1.41mmH2O.

Note that:

The Fractal Design Silent Series R3 fan uses a 3-pin connector. But you don’t need to worry about it’s length it’s long enough to fit anywhere.

4. uxcell SNOWFAN 50mm fan


uxcell produces some of the good quality fans out there in the market.

These fans come with highest quality sleeve bearing.

The fan speed and static pressure might not be too high but they do a good job in cooling.

The thickness of this fan is 0.39inches which is approximately 10mm. So, it’s thin too and will fit in any type of PC.

The one thing you need to keep in mind before buying this fan is:

The connecting wire is only 9inch. So, you will need to be a more accurate in measuring your PC.

5. Scythe Mini Kaze 50mm fan


This is a overall good fan. This fan mainly uses a 2pin connector for the connection.

But the good thing is that:

It also comes with an adapter or 3pin connection.
