Noise, RPM, and airflow. These are the only three things you need to bear in mind when you are looking for a best 140mm case fan. Once the above criteria is matched according to your preferences then you are good to go. Let us further elaborate and simplify so that you can make an informed choice.
First and foremost, you need to remember that airflow is extremely important. It is the air that the fan pushes every minute and it increases when the noise is at its minimum. So, we come to our next important factor, noise. PC cooling is no joke.
A fan needs to rotate at a minimum speed of 2.5 times to ensure effective cooling throughout. This can often get noise, especially at higher frequencies. Naturally, anything above 30/35 dB is a strict no. Next, we go for the RPM or the fan speed.
More...
As the term suggests it is how fast the fan rotates per minute as the faster it spins, the pressure increases thus increasing the airflow. You can often control the fan speed so you might want to check the model’s PWM. I would like to add one final thing that is not often considered but is equally important when you look for a good quality piece and that is the bearing type.
The best option to go for is a fluid-based bearing as they make the least noise by reducing the friction maximum. On the more affordable side of options, you will find bearings made of steel but we have included the one's which has fluid-based bearings for maximum lifespan.
Hopefully, my list nudges you towards the right purchase.
