The Noctua NH-D14 SE2011 edition heatsink is aimed at users running the latest Intel Sandy Bridge-E systems. The Noctua NH-D14 SE2011 CPU cooler retains the same award winning design as the original NH-D14 but comes with a new SecuFirm2 mounting tailored for LGA2011 motherboards as well as having PWM versions of the NF-P12 and NF-P14 fans. These fans paired with the NH-D14 SE2011 heatsink are designed to push a lot of air while maintaining very low noise during operation. Just in case you want to further lower the sound output, you can attach the pair of low noise adapters Noctua has included in the accessory package.///"
