Overview of the Top 9 Quietest CPU Coolers

Not all CPU coolers are created equal. The heatsink and fan blades on certain CPU coolers have been tuned to assist minimize vibration and noise.

The fans also include improved fan bearings and anti-vibration technology, resulting in lower noise levels and improved performance.

The top 9 quietest CPU coolers are as follows:

1. Scythe Ninja 5 is the fifth installment in the Scythe Ninja series.

For overclocked CPUs, the Scythe Ninja 5 is the finest silent CPU cooler.

The following are the highlights of the Scythe Ninja 5:

  • Noise output ranges from 4 to 14.5 dB(A).

At first look, the Scythe Ninja 5 seems to be a twin tower system. It is, however, a single tower heatsink. The heatsink is large, with a large surface area for heat dissipation.

To generate adequate airflow, the tower requires two fans. It does it with the help of two Kaze Flex 120mm fans. The fans are set up in a push-pull arrangement and have a maximum RPM of 800. Anti-vibration cushions are also installed.

And I have to say,

These are among the quietest CPU cooler fans I’ve ever encountered. Even under high loads, they barely reach 14.5 dB(A). They are very quiet thanks to Sealed Precision Fluid Dynamic Bearings.

Also, don’t forget to have a look at our best fanless CPU cooler if you want to run your PC quietly.

The heatsink features recessed fins to allow for up to 55mm tall RAM modules to be installed with adequate space. The CPU cooler is 155mm tall, thus it should fit in most standard PC cases.
