Review: The best CPU cooler under 40mm - 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.
Review: No issues found - This has been my cooler for my daily driver PC. I have had no issues with heat throttling, noise levels are fine. Build quality is what you would expect from anything Noctua. Installation process is quick and easy.

### ⭐⭐⭐⭐⭐ The best CPU cooler under 40mm
*by H***E on November 24, 2025*

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.

### ⭐⭐⭐⭐⭐ No issues found

This has been my cooler for my daily driver PC. I have had no issues with heat throttling, noise levels are fine. Build quality is what you would expect from anything Noctua. Installation process is quick and easy.

### ⭐⭐⭐⭐ Great Cpu Cooler for the Smallest of Small Builds
*by K***R on June 29, 2025*

Great quality which you'd come to expect from Noctua as always. Very much meant for the smallest of small builds as it barely clears a basic vram heatsink in terms of height. Noctua level of quiet, barely can tell the fan is spinning sometimes. Can be a bit tricky to install but a lot easier than some other coolers on the market. If you need an incredibly small cpu cooler for the smallest of small pc builds, this is the one without a doubt.
