Noctua NF-B9 Case Fan Review

Introduction

Continuing with our cooling theme here on Verdis, we take a look at a product from a company that deserves all the accolades it receives. Yes, you guessed it – Noctua. In the past we have seen great performance from products from this manufacturer and so the NF-B9 fan up for review today straight away has high expectations. Let’s hope it can deliver…

Company Information – Noctua

“Noctua aims at establishing a new level of quality and performance “Designed in Austria” through paying attention to the users’ needs in a market burdened with all kinds of frills and furbelows and providing sound-optimised premium components, which serve their purpose in a smart, precise and reliable manner.”

Features

• Bevelled Blade Tips
  Due to advanced design measures like the bevelled blade tips, the NF-B9 is surprisingly quiet despite its outstanding airflow and pressure performance.
• Vortex-Control Notches
  Psychoacoustic optimizations like the Vortex-Control Notches make the NF-B9’s noise pattern more pleasant to the human ear.
• Smooth Commutation Drive
  The new SC drive system reduces torque variations and thereby ensures improved running smoothness, particularly at lower speeds.
• Self-stabilizing oil-pressure bearing
  Noctua’s well proven SSO-Bearing technology guarantees supremely quiet operation and exceptional long-term stability.
