Introduction
The heatsink is a component that helps regulate the temperatures in and around the central processing unit (CPU) on the motherboard. These parts sometimes fail over time and can cause the temperatures to be higher than normal, so it is a good idea to replace them as they age. Excessive amounts of heat can be potentially damaging to various internal components.
Be sure to clean the contact surfaces on both the heatsink and CPU with isopropyl alcohol during replacement and reapply thermal paste during reinstallation. Sometimes reapplying the thermal paste is all that’s necessary to reattain good heat transfer and restore the condition of your device.
