This guide was developed to instruct users on the proper procedures for installing a replacement chipset cooler onto a motherboard. The techniques described would be similar for the replacement of a video card cooling solution. Included are step-by-step instructions for the removal and replacement of the cooling solution.

It should be noted that this guide does not cover the removal of the motherboard that is required prior to the installation of the cooler. For information on this, please see the How to Install a Motherboard tutorial.

Before installing a chipset cooler onto a motherboard or video card, it is important to verify with the manufacturers or other sources that the solution will indeed fit. There are various sizes for the cooling solutions for different video cards and motherboards.

In order to install the new cooler, the previous cooler must first be removed. Locate the cooler on the board and flip the board over. There should be a set of pins that go through the board next to the cooler to hold it onto the board.

Using the needle nose pliers, gently squeeze in the bottom portion of the clip so that it will fit through the board. The pins may be spring loaded and automatically snap through the board when the pin is squeeze inwards.

Heat the Old Thermal Compount

In addition to the mounting clips holding the cooler onto the board, the heatsink itself is typically affix to the chipset using a thermal compound such as thermal tape. Trying to pull the heatsink off at this point could damage the board and chip. This thermal compound needs to be removed.

Take a hairdryer and set it to a low heat setting. Gently aim the hairdryer towards the back of the board to slowly raise the temperature of the chipset. This heat will eventually loosen then thermal compound used to affix the heatsink to the chipset.

Use gentle pressure to slightly twist the heatsink back and forth on top of the chipset. If the heat is high enough, the thermal compound should be loose and the heatsink will come right off. If not, continue heating with the method is step.

With the tip of your finger, press down and rub off any large amounts of thermal compound that remain on the chipset. Do not use finger nails at all so as to not scratch the chip. You may want to use the hair dryer if the compound has become rigid again.

Apply an amount of the isopropyl alcohol to the lint free cloth and then gently rub along the top of the chipset to remove the remaining bits of thermal compound for a clean surface. Do the same to the bottom of the new heatsink as well.

In order to properly conduct the heat from the chipset to the new cooler, thermal compound needs to be placed between the two. Apply a generous amount of thermal grease to the top of the chipset. It should be enough to make a thin enough layer but still fill in any gaps between the two.

Use the new and clean plastic bag over your finger to help spread the thermal grease to cover the entire chip. Make sure to try and get as even a surface as possible.

Align the Chipset Cooler

Align the new heatsink over the chipset so that the mounting holes are properly positioned. Since the thermal compount is already on the chipset, try not to rest it down on the chipset until you are as close as possible to the mounting location. This will prevent the thermal compound from being spread around too much.

Fasten the Cooler to the Board

Typically the heatsink is mounted to the board using a set of plastic pins similar to the ones that were previous removed. Gently squeeze down on the pins to push them through the board. Be careful not to use too much force as to cause damage to the board. It is a good idea to try and squeeze in the pin sides from the other side of the board while pushing the pin through.

Locate the fan header on the board and attach the 3-pin fan power lead from the heatsink to the board. (Note: If the board does not have a 3-pin fan header, use a 3 to 4 pin power adapter and attach it to one of the power leads from the power supply.)

(Optional) Affix Passive Heatsinks

If the chipset also comes with memory or passive southbridge coolers, use the alcohol and cloth to clean the surface of the chips and heatsink. Remove one side of the thermal tape and place it on the heatsink. Then remove the other backing from the thermal tape. Align the heatsink over the chipset or memory chip. Gently rest the heatsink onto the chip and press down lightly to affix the heatsink to the chip.

Once all these steps have been taking, the chipset cooler should be properly installed onto the board. It will now be necessary to reinstall the board back into the computer system. Please refer to the How to Install a Motherboard for the proper method for returning the motherboard back into the computer case.
