Honestly, 90c on that chip sounds like a mounting issue or just bad paste. You dont need anything crazy, but dont use bottom-tier mystery stuff. Grab some quality paste and try again.

• Thermal Grizzly Kryonaut 1g
• Noctua NT-H2 3.5g Be careful how you mount the cooler, too. Uneven pressure is a classic mistake. I would suggest re-applying and really checking that mounting pressure.

> Is the paste supposed to be different for modern chips? Honestly, you dont need special paste, but that cheap local stuff is probably just dried out. I had a nightmare with generic paste on my own build a while back, switching to Arctic Silver 5 3.5g made a huge difference, though it takes forever to cure. If you want something easier, Kingpin Cooling KPx 1g is solid for high-heat chips. Just be careful with the application amount!

Building on the earlier suggestion, you definitely need to swap that stuff out. Honestly, it is such a scam how these companies push generic thermal compounds that just end up failing after a week. It drives me crazy how the quality has gone downhill lately while prices just keep climbing. Like, you shouldn't have to stress about cooking a chip just because a tube of paste was sitting on a shelf for three years, you know? It is totally ridiculous.

• The industry is really cutting corners lately.
• Everything feels like a cash grab now.
• Nobody seems to care about long-term stability anymore. It is just frustrating when you spend good money on a build and the simple stuff lets you down. Definitely clean it off and grab something reliable next time you have a chance.

TL;DR: The cheap paste is likely the culprit, but don't overspend. You dont need special paste, just something reliable. I would suggest Arctic MX-6 4g because it performs great on hot Ryzens without the high price tag. Be careful to clean the old stuff off completely with high percentage alcohol first. Make sure your cooler is tight too, those chips run hot but 90c is pushing it.
