1. Wipe the contact surface of the CPU chip with a clean, lint-free cloth to ensure proper
contact with the new heatsink.
If you removed the original CPU from the motherboard in order to install it on a new
motherboard, be sure to remove all thermal compound residue from the surface of the CPU
and the base of the heatsink. It may help to scrape all the residue off the surface using the flat
edge of a non-conductive tool. Use a lint-free cloth moistened with alcohol to clean the base
of the heatsink.
2. Insert the CPU into the socket. Make sure that you align the arrow indicating pin 1 on the
CPU with the arrow on the CPU socket.
3. Carefully close the socket cover, and lower the socket lever to secure the cover.
