Noctua just sent over two fan models for some testing. The fans are not your standard black or clear with LEDs. These fans are here to move vital air through your case and hopefully drop some temperatures.
Before we get to that, what or who exactly is Noctua? Noctua is named after the little owl that is the symbol of the Greek goddess Athena. She represents wisdom, science, and strategy, which the Noctua company is striving to achieve. Formed by the cooporeration of Austria based Rascom Computerdistribution Ges.m.b.H. and Taiwan based Kolink International Corporation, the research and development shared by the two companies help propell their unique products.
Setting all of the fans down on the desk for pictures, the top one is the 80mm fan and the other two are the 120mm fans. The two toned color of the fans make them stand out in a case and not blend in the background as we will see in a bit.
Wanting to know what the 120mm fan can do, I decided to look at them first.
Taking the fan out of the box we have a better idea that the outer shell of the fan is light pink in color and the blades are more a brown with a tint of red. The cables are wrapped and clean looking, which helps with cable management within the case.
Using a fan less PSU, I can hear a small pulse sound coming from the fan, not the standard constant sound you hear from normal fans. They have employed a novel rotor which was developed by the Austral Institute for Heat-Transmission and Fan Technology.
Replacing the fan in a Cooler Master case, I compared the air flow from both fans and the type of noise.
I placed both 120mm fans in this case in two locations. One in the front and one in the rear. I used the AMD default cooler from my Opteron processor on my AMD 4000+. The heatsink fan is the loudest fan in the case.
The U.L.N.A (Ultra-Low-Noise Adaptor) is a power cable that has a resister in line with the fan, cutting the amount of power that the fans uses, which slows it down. If you use those, there is not a way to speed up the fan without powering it down and removing it. They also have the noise damping pins (vibration compensators) you can use if they fit in your case, it didn't fit mine.
Now letís take a look at the 80mm fan.
