1、CPU heatsink, which can effectively reduce the temperature generated by CPU operation. 2、Special designed for LGA 2011, 1U passive cooling heatsink designed for computer. 3、Reduce the possibility of hardware failure due to overheating, good thermal conductivity. 4、Transfers the heat generated by an electronic or a mechanical device, thereby allowing regulation of the device's temperature at optimal levels. 5、Heat sinks are used to cool central processing units or graphics processors for computer. 1 x CPU Heatsink Condition: 100% Brand NewItem Type: CPU HeatsinkMaterial: Metal Model: SNK - P0047PSPlatform: for LGA 2011Cooling Mode: PassiveInstructions: 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.
