CPU Cooler NOCTUA NH-U9S:The Noctua NH-U9s processor cooler provides excellent performance while remaining compact in size. Its asymmetric design with five heatpipes not only provides better cooling, but also improves compatibility. Thanks to its size, 95x95 mm, the cooler does not interfere with the space dedicated to the RAM or PCI Express slots of most motherboards. In combination with a height of 125mm, you have a guaranteed seamless compatibility with most cabinets.The included NF-A9 fan supports automatic speed control using PWM for quiet operation. If you require more power you can mount a second NF-A9 PWM fan. Installing the entire cooler will make it easier for your proven SecuFirm2 system (installation on AMD requires a backplate). Precise hot air outlet will be aided by NT-H1 thermal grease.Additional information: Material: Copper: base and heatpipesAluminium: ribsStandard accessories: NF-A9 PWM fanAdapter to reduce speed (LNA)NT-H1 thermal grease SecuFirm2 mounting kitClips to attach the NF-A9 fan
