Disappointing Noise Output

As a result of my tests, I determined that this fan is not as quiet as advertised. The noise level was simply too high for my liking..

Pros
  • Easy to install
Cons
  • Loud noise output

Revainrating 5 out of 5

and stays comfortably cool even under full load

Virtually silent. Replaced the fans in my 3Com WX1200 Wireless Network Switch which has 6 PoE network ports and stays nice and cool even under full load and no longer feels like a jet engine!

Pros
  • Award-winning A-Series design with flow acceleration channels and Advanced Acoustic Optimization frame for superior silent cooling
Cons
  • Long wait
