Noctua NH-U12P and NF-P12 Cool & Quiet Review
As we move into the age of multi-core CPU's the importance of using a quality heatsink increases exponentially. The days of sticking any old hunk of metal on top of your CPU are long gone. CPU's have begun to put out enough heat to warm a small room and you need a serious cooler to dissapate that heat. This is where Noctua comes in. Noctua may not be a household name here stateside but they posses a lot of expertise when it comes to keeping PC's cool and quiet. Working in cooperation with the Austrian Institute of Heat Transmission and Fan Technology, Austrian Rascom Computer distribution Ges.m.b.H and the Taiwanese Kolink International Corporation, Noctua has positioned themselves to establish a new level of quality and performance. Today's offering comes in the form of the NF-P12 120mm fan and NH-U12P heat sink. The NF-P12 brings full-sized fins complete with turbulence reducing notches and low noise adapters while the NH-U12P packs plenty of kick with its hybrid copper and aluminum design and high density array of fins.
