Frequently Asked Questions (FAQs)
1. Do you put thermal paste on the CPU and heatsink?
Every CPU cooler needs thermal paste, but many have it pre-applied, which simplifies the installation process. To find out if you have pre-applied paste, check the bottom of the base plate or water block of your CPU cooler that attaches to the CPU.
2. Is thermal paste necessary for CPU?
Thermal paste, or some oily thermal interface material, is necessary because it fills in the microscopic imperfections that otherwise trap air particles between the CPU and the heatsink, preventing the CPU from properly cooling.
3. Is heatsink and thermal paste the same thing?
Heat sink compound (also called thermal grease, thermal compound, CPU grease, heat paste, heat sink paste, and thermal interface material) is a sticky paste that's used as an interface between CPU heat sinks and heat sources.
4. How often should I replace thermal paste?
How Often Should You Replace Thermal Paste? In most cases, you shouldn't need to reapply more than once every few years, though you should replace your paste if you remove your cooler for any reason. You may also want to consider reapplying thermal paste if you find your CPU temperatures are climbing.
