"ARCTIC
fans are able to cool the system more quietly than the stock fans which
aren't even very loud themselves. This was shown in our testing where
we recorded a lower noise level for the system with the ARCTIC fans
installed. One of the main advantages of these ARCTIC fans over other
low-noise alternatives is the impressive price point that they come in
at."
Description
Greater Efficiency - Less Noise at Higher Airflow
At low fan speed, the motor noise is key. A motor developed in Germany
with a new alloy/lubicant combination reduced friction and noise.
Our impeller is quiet and at a given low fan speed, it moves more air than standard impellers at lower generation of noise.
Long Service Life
The Fluid Dynamic Bearing comes with an oil capsule that avoids
lubricant leakage. Thus this bearing is as quiet as a sleeve bearing but
comes with a significantly higher service life.
Innovative Design Enables Quiet and Efficient Ventilation
The innovative design of the fan blades improves the airflow and
facilitates a highly efficient ventilation. The impeller was designed
with a focus on minimzing the noise level yet delivering the desired
airflow and pressure.
