Before buying the best case fan version, make a list of all the important components, qualities, and added functions it may have to make your system more sustainable.
For auxiliary fans, make sure they are lightweight and inexpensive. For primary cooling, check your system specs if they match your desired cooling fan specifications. Lets’ check below the answer of this question, how to choose case fans for your pc.

How to Choose Case Fans for PC
No doubt from the variety of available options in the market, it has become little hard to choose the best case fan. But we still we believe that if you take care of all these below mentioned things, you will be in a position to choose the best pc case fans.
-
Good Quality Motor
A good quality motor is an important factor to investigate while buying a cooling fan. The motor controls the level of noise and a good, technologically modern motor will provide you a cooling fan that has smooth performance and an optimal air movement. A cooling fan can run three times longer on inverter which results in longer battery life.
-
PWM Function
PWM stands for Pulse Width Modulation that maintains the signal of the voltage between fully on and fully off controlling the speed of the fan. To choose a case fan, make sure that it has a 4-Pin connector that authorizes the main board to control the speed of the fan from 800-1500RPM.
-
High Vortex Airflow
Another thing that can be considered while choosing a computer case fan is that one should look for high vortex airflow with turbine blade and frame patented design because it will have extremely silent performance and the air pressure and air-flow of the fan will also be optimum.
-
Diversion Groove Blade Design
If a cooling fan has Innovative diversion groove blade design focus air-flow & optimum cooling efficiency, then it is highly recommendable because it provides a super coherence cooling.
-
Anti-Vibration Pad Design
If a cooling fan has anti-vibration pads then it will always operate silently and will reduce the vibrations efficiently by keeping the noise levels moderate and will also provide quietness of operation, one needs to buy this.
-
Aero Dynamic Design
An aerodynamic shape optimization involves designing the most efficient shapes of bodies that move through fluids. To choose pc case fans, it must be kept in mind that it should have an air-inlet with aerodynamical design to reduce the noisy air turbulence.
-
Hydrodynamic Bearing
Hydrostatic bearings are externally pressurized fluid bearings, where the fluid is usually oil, water or air, and the pressurization is done by a pump. Hydrodynamic bearings depend on the high speed of the journal i.e. the part of the shaft resting on the fluid to provide pressure to the fluid in a wedge between the faces. The HydroDynamic Bearing Technology (HBD) runs more smoothly having no or less friction which makes the cooling fan to operate more quiet and durable
-
Tool-Less Fixed Pins
If the cooling fan contains rubber fixed pins and tool-less fixed pins, it is a highly recommendable fan because the rubber fixed pins reduce vibrations due to which the fan runs quietly and the tool-less fixed pins make it easy for the fan to mount having no tools required.
-
Heat Generation in Micro – Controllers
One must get into account how much heat the system generates. Components like micro-controllers, processors, FPGAs, and MOSFETs are the heaviest consumers of power and hence the major culprits of heat dissipation. These components generate hot spots within the system. However, it is possible to model the resulting thermal profile using computational fluid dynamics (CFD).
-
Airflow Resistivity
Next, one needs to consider the airflow resistivity of our system. Normally, fan manufacturers specify airflow for a given static pressure, i.e. the atmospheric pressure in the enclosure when there is no airflow.
-
Temperature Sensors
The performance of the component and its reliability can be dramatically impaired when operating the cooling fan at higher temperatures. Even though a device will normally have a specified operating temperature range, it’s often desirable to keep the actual operating temperature well below the upper limit of that range.
To determine what airflow (Q) will be required to ensure that component temperatures stay within an acceptable range; we first need to determine an allowable temperature rise (ΔT). Any allowable temperature sensor must have 2x temperature endurance than actually defined in the normal operating range. It allows enough room to clear away any malfunction when the system overheats without burning your fan cooler.
-
Efficiency
To buy a good quality cooling fan one must keep in mind the efficiency of the fan. Cooling fans are usually about 20 percent more efficient than other fans. Models that contain a light are generally 60 percent more efficient than other cooling fans or lights combinations. Also, have a look at the watts of electricity required to run the cooling fan. Average is about 70 watts, so anything less is more efficient.
The more watts a system consumes, the more load it holds other than delivering it to the PC and more are the chances for system to perform underrated. It is better to buy a dual fan with low wattage or better use an external power supply to feed the cooling fans or the system will black out if the load gets higher in overclocking modes.
-
Remote Control
If the cooling has the remote-controlled quality, then it is the most beneficial control option available. The portable and lightweight control can be used within a certain range, which is going to make the cooling fan ideal for hard to reach places and a remote-controlled cooling fan is also perfect for indoors as well.
There are multiple remote-controlled cooling fans available in the market if needed. Mostly, the control is through a Smartphone app via Bluetooth. A mobile app or direct PC GUI displays and monitors all the temperature, pressure, and RPM speed in real-time for user convenience.
Conclusion
The choice of case fans a lot depends on your taste and needs. What is your gaming taste and what exactly are you looking for. Keep all these above mentioned things in your mind along with your pc compatibility. We believe that you will be in a position easily to choose the right case fan for your computer system.
