fans for pc have become one key piece for its operation, many users are still unaware that this type of device is inside the computer case. But the truth of all this is that thanks to this rotating blade the computer does not heat up and allows the same works correctly.
In this way, it could be said that these devices carry out one of the most important functions of these devices, since without them the useful life of the equipment would simply be much less than what they can have with it. Furthermore, it is important to mention that these fans are also known as PC fan.
In accordance with all this, here we are going to explain a little more about what PC fans are, what they are for and how they really work on computers. To do this, follow in detail everything that we will explain in the post.
What is a fan and what is it for in a computer or computer?
These fans for computers their main mission is simply to be able to maintain normal equipment temperature so that he can have a proper functioning. Therefore this physical element is meant for remove any excess heat from any of the components of a computer such as the CPU or graphics card.
This means that if a computer does not have this heat sinkthe temperature can rise more of the tolerable limits of the equipment components, which could cause the damage of the and any other computer part.
All this has made the fans become one essential piece for what it is PC cooling, that is why this device has become a very commercial element where you can currently find different models, sizes and aesthetics.
In this way, if what you want is improve machine cooling and thus increase its useful life, the most important thing is to have a heat dissipator that is capable of Cool all parts of your CPU.
Fan Types How are these hardware items classified?
Currently it can be said that there are two types main fans for computerswhere each of them is used according to the equipment you have.
Accordingly, here we present each of these types:
radial fan
Previously this fan type was the one used on all PCs that went on the market, so it can still be obtained in older computers. However, it is important to note that this type of fan no longer exists today so you won’t get it on the market, at least not new.
Where it can be found is still in graphics cards, since this is used there with very oftenas well as for small teams. This type of fan is known as blowersand has a large number of blades with an empty inner partthis allows an airflow perpendicular to the fan axis is created through the air intake.
All this means that its operation is very similar to what would be the rocket turbo, or to be more specific to what is a aircraft turbine. And the teams that use this device the most are the laptops and consoles due to its small size.
axial fan
It can be said that this pc fan is the most used in this type of computers, it ensures that the air flow passes in a direction parallel to its axis. This means that it is as if it were the propellers of an airplanewhere the fan blades push the air parallel to the axis of the appliance.
In this way, axial fans they can move big volumes of air with very little pressure, So you won’t have to try too hard. thus increasing its useful life. Finally, this kind of fan is the most widely used today in all desktop computers.
What are the main characteristics of a PC fan?
These devices have various types of features which are essential for its operation.
That is why here we are going to present each one of them, allowing you to learn a little more about PC fans:
Airflow vs Static Pressure
In this type of case, you can define two types of fansthose who have few blades and those with many blades. In the case of fans with a lot of blade are primarily focused on generating a large amount of airflow and very little static pressure. That is why this device has been manufactured thinking mainly of those environments where it is not does not present any type of obstacle.
If you analyze what these machines are like inside, you could say that the best option would be to have a fan with few blades. Since these are the same way manage to dissipate heat, generating a lower margin of erroras they dissipate the heat that has been generated instead of cooling itwhere the chances that an error arises are greater. Accordingly, these are ideal for those tight spaces.
generated flow
The generated flow is measured in CFM, which is key to be able to determine the airflow efficiency of a fan. This means that air efficiency is the CFM divided by the wattsall this between the amount of energy which is used to run the heat sink at its maximum speed.
generated pressure
In the case of the generated pressure is measured in mm/H2Oin this case static pressure is the pressure that is generated by the fan, all this as if it were dealing with a aircraft turbineas absorbs at high speed Y dissipate millimeters that are specified after a flow is generated on the opposite side.
Power
Power is measured in RPM, what it is revolution per minute that generates the fan motor during its operation. In the case of the power of an engine is not everything, you must take other types of elements into account such as it is the propellerbeing this another factor to consider and that is very important.
Noise
Noise is measured in dB – decibelis a unit that is used to measure the intensity of sound and other physical quantities. This factor is very important to consider, since the noise will directly affect one of your sensesso it is worth keeping in mind. The less noise, the greater the comfort when using the computer.
Size
The size is also very important to take into account, the same It is measured in mm/cm, so it’s a key factor when it comes to knowing what type of fan to buy. Today the most common fans found on the market have a 120mm and 140mm size, but you can also find some of these devices that you have measures from 80mm to 230mm.
Connection
Finally we found what the connection is, today you can find three types:
- LP4 Molex connector: This type of connection works constantly.
- 4-pin PWM connector: This connection regulates the CFM of digital form.
- 3-pin DC connector: It is in charge of regulating the connection in % of tension of analog form.
The PC fan does not spin or makes a lot of noise. What are the most common causes?
When using a computer usually this It must be silent or if it generates noise it must be minimal. This is because constant noise could cause user fatigue so that it is not convenient or pleasant to have it. One of the reasons why noise is generated in these machines is when the fan stops working properly and starts generating a lot of noise in the appliance.
These noises can look or feel like the equipment is going to explodeso that excessive sound is not synonymous with it working correctly. One of the reasons for this sound may be that the fan You already have considerable wear on your bearings since they suffer natural wear as time goes by. That is, if he pc fan it has been in use for a long time, it may possibly start to present these problems.
In this type of case the best solution is to replace it with a new one what do i know find less affected. Note that the new fan that you add to the machine must have the same dimensions and characteristics. In addition, when installing it you must make sure that both the direction of entry and exit of air be in the right location. This direction comes reflected on the sides of the fans so you should take it into account.
Another reason why this type of problem can be generated is because the motherboard is in charge of control the temperature processorso that the fan works according to the motherboardeither make the heat sink work at higher or lower speed.
if you light the computer and you notice that after a short time the fan starts to sound too much, then it may be because the processor heatsink is very dirtyso that the fan is not able to cool it down enoughthus forcing the motherboard works to the maximum to try to keep the temperature at a minimum level avoiding that other components are affected.
