I'm upgrading to an AM5 system with a Ryzen 7 9800X3D and need help choosing a cooler. I'm considering the Noctua NH-D15 G2, NH-U12A, or the LC1 240 mm liquid cooler. I want the best-performing option that should remain reliable for many years. I won't be overclocking, and the most demanding games I expect to play are Monster Hunter Wilds, Helldivers, and Cyberpunk at up to 1440p. Noise and cooler size matter too, so I'd prefer a Noctua solution if the performance and longevity justify the price.

The NH-D15 G2 is the strongest choice among these air coolers. It should handle the 9800X3D easily, and a large tower cooler has fewer parts that can fail than an AIO. The NH-U12A is still capable, but it gives up performance while costing nearly as much, so it makes less sense here.
If long-term reliability is the priority, I’d choose the NH-D15 G2. Noctua fans and tower heatsinks can be reused across multiple builds for years, while an AIO will eventually need replacement. The performance difference between the D15 G2 and cheaper coolers may only be a degree or two, but the D15 G2 best matches your preference for premium parts and longevity.
The LC1 240 should offer excellent temperatures and potentially the quietest operation, but it’s still an AIO with a pump and more components that can eventually fail. Since the 9800X3D isn’t being overclocked and gaming loads are lighter than sustained all-core workloads, a high-end air cooler is the safer long-term choice. There also isn’t much long-term reliability history for a newer AIO model.
A Thermalright Phantom Spirit 120 SE or Peerless Assassin can cool the 9800X3D for a fraction of the price and perform very close to the D15. That said, if you’ve already used one and disliked its size or fan noise, the Noctua fans generally have a smoother, less annoying sound profile even when measured temperatures are similar.
I’ve used a Peerless Assassin before and thought it worked well, but mine was very large and louder than I wanted. My new case can fit it, but I’m specifically leaning toward Noctua for the quieter acoustics and build quality.
