Reference fan 9 ... in cms

At first glance this fan can seem expensive, but if you want quality you'll get your money.
This fan combines very good performance in cooling and SILENCE in operation ... And here we speak of silence ... He who makes no noise.
The fan is supplied with a comprehensive bundle / package:
Y-adapter, strain relief for yet more silence, extension cord, screws and vibration reducing (For bad cases because the fan does not vibrate, it simply turning.).
The products are guaranteed 6 years, and as my oldest who NOCTUA 6/7 years and still work perfectly (always effective and in silence), the manufacturer knows what it does and does not take too many risks.
The only flaw of this look could be Noctua typed DERRICK / 70 Industrial's ... And as integration and the stuff we get to create a kind geeekienne cosmetology.
In conclusion, this is the top fan that will serve you and LONG WELL.
