Noctua NH-U9B SE2

The Perfect Solution for Small Assemblies

A top-of-the-line CPU cooler that combines small dimensions with high performance. Ideal for HTPC cases. Hot air extraction is provided by a copper base, 8 copper heat pipes and 38 aluminum ribs.

Wide Compatibility

Two 92 mm fans with Low-Noise and Ultra-Low-Noise adapters ensure supreme quietness and maximum performance. The supplied mounting system allows mounting on the LGA1366, LGA1156, LGA775, AMD AM2, AM2 +, and AM3 slots (the AMD slots require the motherboard on which the cooler is to be mounted to be equipped with the appropriate backplate)

Complete Cooling System

The time-tested SecuFirm 2 mounting system allows for easy mounting on a wide range of CPU sockets. Also included in the package is the NOCTUA NT-H1 high-performance thermal compound. The NOCTUA NH-U9B SE2 offers a complete package if you require both quality and quiet cooling.

Super cooler temperature at the maximum load it rises above 40 ° C (AMD Phenom II X4 3.6 GHz)! Especially it is very quiet. Odporúčam!
Quiet temperature dropped to 20 ° C High-quality thermal compound in the package Someone does not have to fit within the housing :-)

I have already several similar dabbled fans and yet everyone is completely satisfied. Relatively higher price compensates for absolute reliability and low maintenance of these fans. Extreme quietness with huge cooling effect as it simply stands.
Extremely quiet even without reducing members. Excellent suction power. The temperature dropped about 25 degrees. The accompanying pasta and all the equipment for easy installation. Precision processing and assembly instructions for beginners. The relatively high price.

Pretty quiet 3pin connector only - some boards it themselves neuregulují
Firm, Neratovice 05/04/2015
Translated by Google Translate

Quiet, very effective, without compromise. Thanks to the fans to be quiet is absolutely noiseless and stress echoes gentle noise that if you do not perceive. For some cabinets and boards too robust.
