CPU Cooler Noctua NH-L9i:This low-profile silent cooler is designed for Small Form Factor and HTPC computer cases. It can be used in a set together with PWM fans with dimensions 92 x 92 x 14mm or 92 x 92 x 25mm. The high-performance cooler combines aluminium plates with a modern heatpipe technology. The device has a copper body coupled with a pair of heatpipes that effectively transfer heat from the copper block to the cooler's large aluminium ribbing. The ribbing is composed of several plates, which together have a sufficient area for the necessary heat exchange.The cooler is compatible with the 92 x 92 x 14mm Noctua NF-A9x14 PWM fan with PWM control. The fan achieves a speed of 300-2500rpm with a flow rate of 57.5m3/ha and a noise level of 23.6dB. With the LNA adapter, the revolutions can be reduced to 1800rpm and the flow rate to 40.8m3/h, which will result in a noise level of 14.8dB.Parameters and Specifications:Compatibility:Intel: LGA1150, LGA1155 and LGA1156Dimensions:95 x 95 x 37mm with a fan95 x 95 x 23mm without a fanWeight:420g with a fan345g without a fanMaterial:Heatpipe, aluminium ribbingCooler Design:ActiveFan compatibility:92 x 92 x 14mm, 92 x 92 x 25mmFan:Model: NF-A9x14 PWMBearings: SSO2Speed: 2500rpmSpeed: 1800rpm with an LNA adapterSpeed: 300rpm with a PWM fanAir flow: 57.5m3/hAir flow: 40.8m3/h with an LNA adapterNoise level: 23.6dBNoise level: 14.8dBConsumption: 2.52WVoltage: 12VMTBF: 150,000hrsPackage contents:NF-A9x14 PWMLNA AdapterNT-H1 high-grade heat conductive pasteSecuFirm2 assembly kitScrews for the 92 x 92 x 25mm fanNoctua Metal Case-Badge
