Noctua NH-L9a-AM5 chromax.black, High-Performance Low-Profile CPU Cooler

This is being used in my latest ultra-compact ITX gaming build. It’s cooling an AMD Ryzen 5 9600 x CPU and has been performing well so far. The installation was pretty straightforward the base is fitted directly to the motherboard. Just be very careful not to overtighten the Allen bolts or you risk damage to the AM5 socket.Actual performance has been good so far, it keeps the CPU in the high 80s under load. It’s not as quiet as I was expecting, bit that may be partly down to it being in a tiny ITX case. It ramps up and down with PWM nice and quickly and even shuts off for passive cooling when the CPU is at or near idle.I prefer the black colour scheme over the traditional retro colours of the Noctua fans. The build quality and appearance are also top notch.

Keeps the Ryzen 7800X3D cool while in a K39 case.

SFF ケースで組んだ際に本製品を使用しました。ちょっと高めなので迷いましたが、非常に満足しています。非常に質感が高く、見目麗しいです。回転数が上がっても静かで、ケースを足元に設置していることもあるとは思いますが、音は気になりません。自分の場合回転数の上がる用途は FF14 をプレイする際と、HD の動画編集です。CPU は Ryzen 7 9700X です。OS の設定でちょっとクロック数を抑えていますが、そうするとせいぜい 80 度くらいまでしか上がりません。標準のオーバークロックする状態で長時間負荷をかけると、さすがに上限の温度に達します。ハイエンドな TDP の高い CPU を使うのでないなら、十分かと思います。

Bolts included

This review doesn't exist in a vacuum, as I tried almost every other cooler at this size constraint, and the others don't perform as well. The total mass of the unit, the AM5-optimized hot-spot dissipation, and the manufacturers obsessive commitment to noise reduction = the best AM5 CPU cooler under 40mm. The competition is both louder and less efficient, as they either haven't optimized for the AM5 hot-spots or don't have enough total mass to soak the heat for air transfer. And just to add more QOL improvements, the Noctua NH-L9a-AM5 has the easiest installation, the best fit and finish, clear and detailed instructions, field-leading thermal paste, and additional hardware for mounting taller fans. As always, they include their "low-noise" adapter cable, in a tidy little package that exude quality.

Very disappointed ! perform worse than the original amd wraith fan that come with the cpu.The original Amd fan is very much better except for the size.(Both about same rpm)The only thing that is good (Noctua) was the size.
