If you are installing the motherboard in a case with a removable plate, the only .....
Your motherboard should now be installed on the motherboard plate. The reason for installing it on the plate before adding the components, like the CPU, is to minimize the amount of handling the motherboard receives, as once it's mounted on the plate, there will be a very little need to touch the motherboard itself.

However, as we noted in the previous article, some cases do not have a removable plate. In this case, you must install all the components on the motherboard before installing it in the case.

Switches and Jumpers

Before installing the CPU and memory chips, you will need to refer to your motherboard manual to find the correct settings to configure it for bus speeds and voltage settings. This is usually accomplished by changing a series of switches or placing jumpers on various pins.

Motherboard - Part 1
When you open up a computer case, you see a large printed circuit board underneath all the .....
There are two voltage settings that need to match your CPU; core voltage and I/O voltage. You may find the core voltage printed on the CPU itself, and the I/O voltage also needs to be set according to the CPU specs. Although, some motherboards detect voltage automatically, in which case you do not need to worry about the settings.

The second setting for the CPU is the system bus speed. This is set using a series of jumpers to match the speed of the CPU. The jumpers are small pieces of plastic with metal contacts inside. They fit over pins on the motherboard so that two pins are connected. Consult your manual for the correct jumper placement.

Depending on your motherboard, there may be other jumper settings necessary for the type of power supply, RAM speed, and enabling or disabling onboard controllers. Check the manual for all the settings that are required.

CPU and Cooler

Most CPUs are designed with an array of pins which fit into corresponding holes on the CPU socket of the motherboard. The latest CPUs from Intel are the contrary -- the pins are on the motherboard and the holes are on the CPU. No matter which type of CPU you have, before installing the CPU inspect the pins to make sure that they are straight, if they are bent, they need to be returned to the retailer.

The CPU is held in place with a lever which exerts a small amount of force on the pins. The lever is located on the side of the CPU socket. Orient the CPU by lining up the clearly marked pin number one. Let the CPU fall into place and secure it by replacing the lever.

With the CPU in place, you can install the cooling unit. This is the finned metal block with the fan attached to it. The block is the heat sink. Its large surface area dissipates heat quickly and the fan blows cool air through it for maximum cooling.

Motherboard - Part 2
Buying a new motherboard requires several considerations. If you are going to use your existing CPU, you are limited to buying a motherboard .....
The heat sink must come in direct contact with the CPU. Because the CPU or the heat sink (or both) may have uneven surfaces a pad or paste can be used to provide maximum contact between the two. The thermal pad or thermal paste is placed on the raised part in the middle of the CPU. If using thermal paste, a small dab the size of the grain of rice is sufficient.

The cooler should come with a variety of attachments for different CPUs. Refer to the cooler's documentation for choosing the correct attachments. The attachments usually fit to the CPU socket with either 2 or 4 attachment points and will probably require a little bit of force to clip the cooler securely in place.

The cooler can now be connected to the power source near the CPU. Look for a 3-pin power lead marked "CPU Fan."
