What air cooler would you get for a 9800X3D if you want it to last?

I'm looking for a reliable air cooler for an AM5 build with a 9800X3D. The Noctua NH-D15 G2 looks good but expensive. Would the original NH-D15 be enough, or is something like a Thermalright a better buy? A good warranty would be a plus.

The Thermalright Phantom Spirit 120 or Peerless Assassin 120 would be my pick. Both are strong dual-tower coolers for the money and should handle a 9800X3D without needing to spend Noctua prices.

The heatsink itself has no moving parts. Fans can eventually fail, but they're replaceable, so you don't have to buy a whole new cooler if one stops working. Check case and RAM clearance before ordering.

I'd use the included fans first rather than buying expensive replacements upfront. You can always change them later if the noise bothers you or one fails.

Yes, the original NH-D15 should be sufficient for a 9800X3D. The G2 isn't a requirement just because it's the newer model. If you value Noctua's build quality and support, the original is worth considering when the price is right.

Check that the particular cooler includes the mounting hardware you need for AM5, especially if you're buying older stock or a used one. It's a large cooler, so check clearance too.

Take a look at be quiet!'s Dark Rock range as well if noise and appearance matter to you. Compare the specific model against the Thermalright and Noctua options in recent cooler reviews, including tests at matched noise levels. A cooler that's quiet on a different processor won't necessarily behave the same way on yours.
