Chipset coolers typically include a heatsink and a CPU fan, but they can have just one or the other. These instructions apply broadly to computers made by different manufactures. Consult your device's manual for specific guidance on replacing components. What You Need to Install a Chipset Cooler Before installing a chipset cooler onto a motherboard, it is important to verify that the unit will fit since they come in various sizes. In addition to the cooling unit, you'll need the following tools for opening up your computer: A screwdriverNeedle-nose pliersLint-free clothIsopropyl alcoholA hairdryerThermal paste and/or thermal tape (if needed)A clean plastic bag There are other ways to keep your computer from overheating such as keeping it clean and stored in a cool location. How to Install a Chipset Cooler To remove your computer's old cooling unit and replace it with a new one: Remove the motherboard if necessary to access the cooling unit. If your CPU heatsink/fan/cooler is attached by screws, you may not need to remove the motherboard from the computer. In order to install the new cooler, the previous cooler must first be removed. Locate the cooler on the board and flip it over. There should be a set of pins that go through the board next to the cooler to hold it onto the board. Remove the mounting pins holding the unit in place. 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 squeezed inwards. Newer coolers may be attached by captive screws mounted to the motherboard. Captive screws are never fully removed from the device; they unscrew and stay connected. Heat the old thermal compound. In addition to the mounting clips holding the cooler onto the board, the heatsink itself is typically affixed 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, so the thermal compound needs to be removed. Take a hairdryer and set it to a low heat setting, then gently aim the hairdryer towards the back of the board to slowly raise the temperature of the chipset. The heat will eventually loosen then thermal compound used to affix the heatsink to the chipset. Remove the old heatsink. Use gentle pressure to slightly twist the heatsink back and forth on top of the chipset. When the thermal compound is warm enough, it will loosen and the heatsink will come right off. If not, continue heating with the method in the previous step. Do not overheat as it will cause damage to the motherboard. Clean off the old thermal compound. With the tip of your finger inside a lint-free cloth, press down and rub off any large amounts of the thermal compound that remain on the chipset. Do not use your fingernails because they can scratch the chip. You may need to use the hairdryer if the compound has become rigid again. Apply a small 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. Apply a new thermal compound. In order to properly conduct the heat from the chipset to the new cooler, a thermal compound needs to be placed between the two. Apply a generous amount of thermal paste 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 a new and clean plastic bag over your finger to help spread the thermal compound so that it covers the entire chip. Make sure to get as even a surface as possible. Do not use so much thermal compound that it squishes out the sides when you replace the heat sink. It could get on electrical connections and cause a short. Align the new chipset cooler. Align the new heatsink over the chipset so that the mounting holes are properly positioned. Since the thermal compound is already on the chipset, try not to place 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 motherboard. Typically, the heatsink is mounted to the board using a set of plastic pins similar to the ones that you previously 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. If your heatsink/cooler has screws instead, pay attention to the numbering on them. Do not over-tighten, as this will cause damage to the CPU underneath. Attach the fan header. Locate the fan header on the board and attach the 3-pin fan power lead from the heatsink to the board. 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. Affix any 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. Reinstall the motherboard and reassemble your computer. You should no longer have any issues with your computer overheating.
