Much like its larger brethren, the NH-U9B Special Edition is a high quality heatsink with a ton of technology behind it. From the SSO bearings and Vortex Control Notches on the fans, to the build quality and darn-near universal SecuFirm2 mounting mechanism, to the NH-T1 thermal paste - it is all designed for a purpose. That purpose is to deliver excellent cooling capabilities, while keeping noise to a minimum. This goal, Noctua has been successful in achieving.
