I've always loved and respected the way Corsair products are made. All Corsair products are always of the highest quality and made with real passion. Now that that is said, there are thermal greases. not as much. Even compared to Artic Silver, MX-4 and Grizzly, both pastes don't really lead. Grizzly literally blows this thing out of the park. It's not the worst paste, only $16 for this "ultra" XTM 50 thermal paste, at least I expect higher temperatures than my MX-4. If you're using AMD Ryzen and something bigger, the applicator is too small and doesn't cover the entire surface of the CPU. While I will say that 30C idle and 75C under load at 4.2GHz on my Ryzen 2700x isn't that bad, just not the best.
