If you are considering, now that summer is coming, change the fans of your PC and thus improve cooling, below we are going to think about some of the most important characteristics that we must take into account to choose the one that best suits our equipment.

Start with size in mind
It is essential that we first take into account that there are different computer fan sizes, which adapt better or worse to certain towers or even to specific configurations that we want to use.
However, the most common thing is to find measurements between 120 mm and 140 mm, but it is essential that we take measurements before warming up with motors and other configurations since we can find fans ranging from 80 mm and up to 230 mm.
The most common type of fan
As a general rule, in our case we are going to opt for the axial fans, since they are the ones most frequently used in computers today.
Also exist radial fans, but they have finally been relegated for graphics cards, while with the axials today we have very good results for a much cheaper price.
Number and dimensions of blades
On the other hand, you will have observed that some fans have very small blades and a greater number and other blades of larger dimensions and a smaller number.
The smaller and more numerous they are, we will enjoy a greater air flow., and The larger and thicker they are, the greater the static pressure will be. thereby improving air circulation between the blades.
Generally the best option will be thick and fewer blades.
Choose a suitable bearing
We must also take into account the bearing used, and in this sense we will find three possibilities.
On the one hand we have the sleeve bearing which would be the cheapest and most structurally simple bearing. Being surrounded by oil, it is a very quiet fan, although over time it will lose this lubricant, which in turn will lose effectiveness and its noise will increase considerably. However, it is important to keep in mind that we can also renew the lubrication when we see that it starts to make noise.
This type of bearing is designed to operate vertically, so if we are thinking of installing it horizontally, we will be losing the few advantages it offers over other types of bearing.
we also have the Ball bearing which would be the one that offers us greater reliability. It works with a much wider temperature range while resisting dirt much better, promising a useful life of up to 80.000 hours and offering the possibility of using it both vertically and horizontally.
And finally we have the fans with fluid bearing which is much more complex and offers a scheme similar to what we would find in the case of the sleeve bearing, although obviously with greater durability (with approximately 150.000 hours) but for a much higher price.
