Low Profile - The total height is 12mm which reduces the likelihood of interference with other components and provides the best efficiency within a limited space. Multiple push pin locations for universal mounting on various board assembly. (hole to hole distance 54.6mm and 59m). Formed of pure copper for enhanced thermal conductivity. Excellent surface flatness minimizes the interface between the heat source and heat sink. Dimension 37x37x13.5(H) mm Weight 51g Material Forged copper 1100 Base Flatness Polished mirror surface, flatness for machined surfaces are typically in the range of 0.0003" to 0.0004"per inch Fan Specifications Manufacturer: Adda Size: 35x35x6 mm Part #: AD3512MB-K73S Volts: 12v DC Current: 0.06 amp Power: 0.72 watt RPM: 8000 CFM: 4.7 Noise: 28 dB(A)
