If you’ve procured some second-hand PC components, you might find it necessary to have a tube of thermal paste to correctly set up your new accessories. Changing the thermal paste in your laptop could be on your agenda if you observe that your device is operating at a higher temperature than normal, resulting in unexpected shutdowns. However, since thermal paste has very particular applications, you are likely to end up with a considerable amount left in the tube after finishing your DIY task.
This raises the question: What is the lifespan of thermal paste after being opened? In general, an opened tube of thermal compound can be utilized for about 2-5 years. Certain brands assert that you can get as much as 8 years of usage, but it’s advisable to play it safe and adhere to the lower end of that range.
You’ll also want to look out for any liquid or dry flakes that may emerge from the tube along with the typically grey paste, as the liquid usually suggests that the thermal compound is beginning to separate. A compromised compound might also emit an unusual odor. Fortunately, thermal paste is relatively affordable: a new tube generally ranges from $10-15, and if stored properly, it should be capable of retaining its full shelf life.
