How to Use Thermal Grease
Thermal grease (same as thermal paste) is a substance used to direct the flow of heat from a sensitive device (such as a computer chip) to a heat sink, which absorbs or dissipates the heat. This grease has metallic compounds and ceramic elements, facilitating the drawing of harmful heat buildup to an inert metal. Although it can be challenging to access the device needing new thermal grease, the actual application of it is not difficult. Does this Spark an idea?

1
Access the device needing to be cooled. You may need to separate it from the heat sink using a Phillips-head screwdriver or another type of screwdriver. Remove the device from the heat sink, and set it aside.
-
2
Flip the device over, exposing the old thermal grease (if present). Apply a small amount of isopropyl alcohol to a clean cloth and carefully wipe off the device until as much old grease as possible is removed. Do likewise for the heat sink.

3
Apply a BB-sized amount of thermal grease to the applicator. An old credit card is a good applicator tool. Using a small unidirectional motion, apply a thin coating to the device. Do not apply too thick of a coat, as this will actually impede the heat transfer process.
-
4
Apply the device to the heat sink, straight down to avoid smearing the grease. Reattach any mounting screws or clips, using the appropriate screwdriver.
-
5
Turn the appliance or component back on and confirm normal operation.
