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)
