NH-D9DX I4 3U - Noctua CPU Cooler NH-D9DX i4 3U S2011-0-2011-3 92x92x25mm SSO2-Bearing PWM Retail

3U compatibilityThe NH-D9DX i4 stands only 110mm tall. This is 15mm less than previous 4U compliant 9cm DX-line coolers and allows the NH-D9DX i4 to also fit 3U cases - ideal for noise-sensitive 3U applications in fields such as audio or video processing! 100% RAM compatibility With its 95x95mm footprint, the NH-D9DX i4 does not overhang the RAM slots on LGA2011 Square ILM, LGA1366 and LGA1356. This gives the user full access to the memory modules and guarantees 100% compatibility with tall heatspreaders or optional memory fans. NF-A9 premium fanThe highly optimised NF-A9 premium fan features Noctua's proprietary AAO frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, which allows it to further improve the renowned efficiency of Noctua's previous 92mm models and contributes to the NH-D9DX i4' superior cooling performance. PWM support and Low-Noise AdaptorThe NF-A9 92mm fan supplied with the NH-D9DX i4 supports PWM for convenient automatic speed control through the mainboard. In addition, the maximum fan speed can be reduced from 2000 to 1550rpm using the supplied Low-Noise Adaptor for even quieter operation.Socket compatibility Intel LGA2011-0 LGA2011-3 (Square ILM Narrow ILM), LGA1356, LGA1366 (wtih Xeon backplate) Material Copper (base and heat-pipes), aluminium (cooling fins), soldered joints nickel platingFan compatibility 92x92x25Scope of Delivery NF-A9 PWM premium fan Low-Noise Adaptor (L.N.A.)
