The Cooler Master Blade Master 120 is the best 120mm case fan because it has excellent craftsmanship and performance. Cooler Master always produces the best cooling components, and this product is no exception. It is a premium case fan that has strong airflow and a silent operation.


If your computer components are high-performance, they will produce a lot of heat and a 80mm/92mm case fan may not provide enough cooling. In that case, you may need one 120mm case/radiator fan or more to do the job. But there may be too much energy consumption and noise if you use a regular 120mm case/radiator fan.

As we know, the PWM function can reduce both energy consumption and noise while keeping a nice balance between strong cooling and low noise output. So, if you want to find the best 120mm case/radiator fan, you should look for fans with the PWM function.

Also, to judge whether a case fan is good or not, you should find out the maximum airflow or speed of the product. Usually, a case fan with low airflow or speed can’t be good, and you shouldn’t waste your money on it.

The next thing you should find out is the noise level. If the maximum noise level is under 20dBA, this product can be a good pick. But don’t forget to check the cooling performance, because such a product definitely has weak airflow if it doesn’t have PWM function.

Also, the service life expectancy and the price are important. You can know not only how much you can save if you buy the product, but also how quality is it. To save your time and energy, we tested dozens of popular products on the market and picked 5 out of them. They are the best 120mm case fans on the market, with great performances and reasonable prices. You can’t be wrong if you go with any of them for your computer.
