Thermal tape

Thermal tape are made of special conductive compounds designed to rapidly and efficiently transfer heat. It create a better seal between the CPU and the heatsink. Use thermal paste (instead of tape) whenever possible, because it makes it easier to replace or readjust the heatsink if something goes wrong. Thermal tape doesn't seem sticky at first but turns into glue once it heats up, making heatsink removal a chore.

Thermal tape property

Use thermal tape and paste. Anyone who's looked into installing a CPU heatsink has probably seen recommendations to purchase some thermal paste (also called "thermal compound" or "thermal grease") or thermal tape. This isn't just a good way to squeeze a few extra bucks out of an unsuspecting customer; if you install a CPU without using some, there will definitely be heat problems.

Looking at the metal portion of a CPU and the flat side of a heatsink (which makes contact with the CPU to transfer heat away), both appear smooth. But as far as heat is concerned, those two surfaces are as jagged as the Rocky Mountains, and only a fraction of the surface area of one actually makes contact with the surface of the other when they are pressed together.
