Intel Socket Heatsink Processor

Installing the CPU Heatsink Correctly
Place your computer case down flat with the motherboard and processor facing you. Remove the heatsink from the processor box and check the bottom to make sure that the thermal interface material on the bottom is undamaged. You don't need to add any additional thermal paste or other materials. If the heatsink didn't come with any thermal compound applied, add a small amount to the top of the Intel processor and spread it around evenly. Never install a heatsink without thermal compound.
