The Corsair HD140 is the best 140mm case fan because it is a premium quiet 140mm fan with high performance and great quality. You can hardly find another fan that is totally silent while providing strong cooling.


As computer components demand higher performance, they will produce very more heat. With the best 140mm case/radiator fans you can keep your computer nice and cool for long periods of time. No matter what game you play of what job you do, a computer with such cooling components will never fail.

In the world of computer component cooling, energy consumption and the noise can be big problems. If your fans keep working at full speed all day long, they will waste a lot of electricity and the noise can be endless. The key to the problem is the PWM function which allows fans to reduce both the energy consumption and the noise. Also, it keeps a nice balance between strong cooling and noise reduction. So, before you purchase anything, you should focus on case fans with the PWM function.

The next thing is to find a brand name fan with nice cooling and a quiet operation. Usually, a good 140mm case fan can produce 70CFM of airflow. Also, if the maximum noise level is under 20dBA, it should be a nice choice. It’s hard to find the balance between cooling performance and sound output, but with some premium products you may not need to face this problem.

Additionally, we need to remind you that the service life expectancy is important. A long lasting case fan usually has more stable performance.
