Was a skeptic about thermal paste replacement schedules, but last week I proved myself wrong

Honestly, I used to roll my eyes at people who said you should repaste your CPU every 12-18 months. Figured it was just placebo or a way to sell more thermal paste. But last week I pulled my old Ryzen 5 3600 cooler off after two years of gaming and photo editing. The paste was completely dry and crumbly, like old clay. Temps dropped a full 8 degrees after I put fresh Arctic MX-4 on. I was wrong and now I'm telling every coworker at Micro Center to do theirs too. Anyone else been burned by thinking their paste was fine when it wasn't?

Did you try scraping any off with a plastic spudger or just wipe it with alcohol?

Actually @kelly.nora I'd just let it soak in alcohol first and gentle scrape later.

You say 8 degrees like that's some massive victory but modern thermal throttling doesn't kick in until way above that threshold... most people won't even notice a difference in real world use. I've run stock Intel paste for five years straight on an old 4790K and it still booted fine, temps were in the 70s under load, never crashed once. The whole "replace your paste every year" thing is mostly a marketing push from companies that want to sell you tiny tubes for $10. Unless you're overclocking or running a laptop that bakes itself to death daily, the stock paste lasts way longer than people give it credit for. All that dry crumbly stuff you saw? That's mostly the carrier evaporating, the actual thermal compounds still do the job even when they look ugly.
