When your CPU temperatures start creeping into the mid-80s, it’s hard to resist the temptation of replacing your stock thermal paste with a premium aftermarket one like Thermal Grizzly Kryonaut or Noctua NT-H2. After all, it almost feels like a guaranteed way to drop a few degrees without changing anything else. You remove the cooler, apply a fresh coat of paste, and expect instant results. And considering it typically costs around $15, it seems like a small price to pay for what you get in return.
