How long does the thermal paste behind my CPU last?

Generally, a tube of thermal paste can last up to 3-5 years, but this does vary depending on your specific situation. Important things to consider are the thickness of the paste (the thicker it is, the better), how often you clean your CPU and heatsink (everyday if possible) and what kind of temperatures you’re using from your CPU cooler throughout the day. So as long as you care for your PC, you should practice good habits such as cleaning your CPU every time you remove it or replacement/upgrading after 3-5 years (or sooner if there’s problems).
