[. . . ] Universal design fits all mainstream platforms Omni-directional cooler design with new advanced sintered powder wicks Quad-Way Airflow Design - Fully compliant with MOSFET thermal functions Solid pure copper base with nickel-plating finish High-density fin placement maximizes heat dissipation area Value adding accessories The cooler fan speed levels provided are for reference use only. [. . . ] Figure 2 From the underside of the motherboard, use screws (4) and plastic washers (4) together to secure the LGA775RM into place. Figure 3 Gently push down on the cooler unit to lock it into position. Figure 1 Please add an adequate layer of heat sink paste on the surface of the CPU(Figure1-1). Figure 1-2 showing the correct installation of the cooler atop the CPU. Figure 3 Secure Parts A, B, and then C of the clip to the retention mechanism. Figure 4 If fan speed control is required, please refer to "Installation of the Fan Speed Control Cable". Figure 1 Please add an adequate layer of heat sink paste on the surface of the CPU. Figure 1-1 Figure 1-2 Figure 2 Figure showing the correct installation of the cooler atop the CPU. [. . . ] The original fan speed of 2, 450 Figure 3 rpm will then drop down to 2, 000 rpm. [. . . ]
