Some quality bearing shells and their own SSO2 Bearing again makes Noctua confident enough to give you 6 years of warranty with a MTBF of 150.000 hours. That means it should last you when spinning 24 hours a day for 6250 days, that’s over 17 years running 24/7
Again coming with a nice plethora of mounting options, removable anti vibration pads, extra leads and even a Y splitter (*cough* 140mm *cough*).
So in short, what can I say… The NF-A15 and NF-A14 cooling fans are proper Noctua quality with added new innovations. With every new design they unveil, Noctua brings out great airflow with minimal noise and are extremely reliable (I still use 5 year old Noctua fans). They are a bit more expensive than typical case fans but are worth every penny.
