10 Best 120mm Case Fan 2022 – Reviews & Guide
A 120mm case fan is a 120mm x 25mm fan that attaches onto the side panel of your computer case. The purpose of a case fan is to keep the air moving around in your case so that it doesn’t get stagnant and hot. Most cases ship with one or more fans, but they’re almost always underpowered and inadequate.
The 120mm case fans are quiet while delivering enough airflow to cool your components. They also look great in any build and come in different colors, so you can match them to your build theme.
As a consequence, there is a rise in the temperature of your PC. Your processor and other components can get damaged due to overheating. So buying a good quality CPU fan for your computer is essential.

PCs with not enough ventilation are more prone to heating. To keep your computer cool, you should buy a CPU fan, as a good one will have excellent thermal management and low noise levels, which will help you concentrate on your work.
Are 120mm fans enough?
A 120mm fan is a very common size, it’s quiet and moves a good amount of air. You could also get an 80mm fan, which would be quieter and move less air, but you have less choice in the matter. If you want something quieter and move even less air, you’re going to have to mess around with trying to fit a bigger fan into the case.
If you get a 140mm fan or larger, the noise reduction is pretty big, but there isn’t a huge difference in airflow. However,140mm fans won’t fit in a lot of cases so that may not be an option for you.
Is 1200 RPM fan enough for PC?
No, 1200 rpm is not enough for a PC. A case fan should be at least 2000 RPM (rated) and preferably higher.
Generally you want fans that exhaust more air than intake, because the processor and GPU produce more heat than the power supply does. If you only have one fan, it should be an intake in the front of your case, but if you can afford it, get two fans and put one on the side panel as an exhaust.
