Features: 1CPU heatsink, which can effectively reduce the temperature generated by CPU operation. 2Special designed for LGA 2011, 1U passive cooling heatsink designed for computer. 3Reduce the possibility of hardware failure due to overheating, good thermal conductivity. 4Transfers the heat generated by an electronic or a mechanical device, thereby allowing regulation of the device's temperature at optimal levels. 5Heat sinks are used to cool central processing units or graphics processors for computer. Condition: 100% Brand New Item Type: CPU Heatsink Material: Metal Model: SNK - P0047PS Platform: for LGA 2011 Cooling Mode: Passive Instructions: 1. Place the heat sink directly on top of the CPU so that the heat sink screws are aligned with the mounting holes on the backboard. 2. Ensure that the screwdriver torsion setting is not more than 5.0kgf-cm (4.3lbf-in) and keep the heat sink screw orientation vertical. 3. Tighten the two diagonal screws ( 1 and 2 screws) so that they are tight (do not tighten completely).Then, do the same with the remaining two diagonal screws. 4. Finally, tighten all screws completely. Package included:1 x CPU Heatsink
