Dried out my thermal paste for 8 months before I realized

I kept wondering why my 2007 ThinkPad was overheating even after I cleaned the fan. Turns out I was leaving the tube of Arctic Silver open between uses and it hardened into crust. A buddy in a Discord server told me to check the consistency and it felt like clay. $8 replacement tube fixed my temps by 15 degrees. Anyone else ruin paste by storing it badly?

Had a buddy who did the exact same thing with a tube of Noctua paste. He left it in a hot garage for like six months and when he finally squeezed it out, it came out all crumbly like dried Play-Doh. His CPU was hitting 90 degrees under load and he was ready to buy a whole new cooler. I stopped by with a fresh tube from Micro Center and his temps dropped 20 degrees instantly. He still jokes about his "concrete thermal paste" whenever we talk PCs now.

The real killer nobody talks about is the tube design itself has a stupidly short shelf life once you crack the seal. Arctic Silver and most pastes have a solvent that evaporates out, and that little cap does jack squat once air gets in there. I've seen people store them perfectly, fridge and everything, still turn to chalk in a year because the tube's plastic lets moisture through. Solution nobody wants to hear is to buy the smallest syringe you can find and treat it like single use, or just use the paste packets that come with coolers. The whole "big tube saves money" thing is a trap because you never use more than a pea sized amount anyway. Shame on them for selling 10 gram tubes when 3 grams would last a normal person five years.
