Bent pins may result in short circuits or cause fire. Before installing acomponent on the motherboard, be sure to carefully inspect the CPU,the socket and the motherboard for bent pins. If you find any bent pins,do not continue with component installationAfter you've inspected the CPU, CPU socket, load plate, and other components, making sure that every component is in good working condition, thenyou can insert the CPU into the socket.1. Using your thumb and the index finger, hold the CPU at the north andsouth center edges.2-71

CPU/Heatsink Installation and Removal User's Guide2. Locate Pin 1 of the CPU, which is marked with a goldtriangle on the CPU. Locate Pin 1 of the socket, which is23marked with a triangle on the socket or the motherboard.3. Align Pin 1 of the CPU with Pin 1 of the CPU socket.4. Locate the CPU keys, which are the semi-circle cutoutson the sides of CPU, and the socket keys, which are thenotches on the sides of the socket.45675. Align the CPU keys with the socket keys.6. Once both the CPU and the socket are aligned, carefullylower the CPU straight down into the socket. Do not rubthe CPU against the surface of the socket or its pins toavoid damaging the CPU or the socket.7. With the CPU in the socket, inspect the four corners ofthe CPU to make sure that the CPU is properly and fullyseated in the CPU socket.2-8

CPU/Heatsink Installation and Removal User's Guide2.3CPU Heatsink/Fan Installation1Installing a Passive Heatsink1. Do not apply any thermal grease to the heatsink or the CPU die because therequired amount has already been pre-applied.2. Place the heatsink on top of the CPU so that the four mounting holes arealigned with those on the retention mechanism.33. Install two diagonal screws (i.e. the #1 and the #2 screws) and tighten themuntil just snug (-do not fully tighten the screws to avoid possible damage tothe CPU).44. Finish the installation by fully tightening all four screws.2-102

Chapter 2: CPU and Heatsink InstallationThermal GreaseInstalling an Active Heatsink Fan1. Locate the CPU fan power connector on the motherboard.2. Position the heatsink so that the heatsink fan wires are closest to the CPU fan powerconnector and do not interfere with other components.3. Inspect the CPU Fan wires to make sure that the wires are routed through the bottom ofthe heatsink.4. Remove the thin layer of protective film from the heatsink.Warning: CPU overheat may occur if the protective film is not removed from theheatsink.5. Apply the proper amount of thermal grease on the CPU.Note: if your heatsink came with a thermal pad, please ignore this step.6. If necessary, rearrange the wires to make sure that they are not pinched between theheatsink and the CPU. Also make sure to keep clearance between the fan wires and thefins of the heatsink.2-11Heatsink Fins

CPU/Heatsink Installation and Removal User's Guide7. Align the four heatsink fasteners with the mounting holes on the motherboard. Gently push thepairs of diagonal fasteners (#1 & #2, and #3 ) into the mounting holes until you hear a click.Also, make sure to orient each fastener so thatthe narrow end of the groove is pointing outward.8. Repeat Step 7 to insert all four heatsink fastenersinto the mounting holes.9. Once all four fasteners are securely inserted intothe mounting holes and the heatsink is properlyinstalled on the motherboard, connect the heatsink fan wires to the CPU fan connector.2-12
