Noctua NH-L9a-AM5 chromax.black, Premium Low-Profile Processorkoeler voor AMD AM5 (Zwart)

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

Was more difficult than expected to install on AM5 CPU. Must be screwed from the back similar to other slim profile cooler, but there is a gap between the cooler frame and motherboard making it difficult to find the proper pressure to tighten the screws. Not what I was expecting from a high-end cooler. I ended up returning it.

Sicuramente uno dei migliori dissipatori per le sue dimensioni veramente ridotte, inoltre ha un bellissimo design. Ho anche il modello per intel che a differenza di questo per Am5 si può posizionare in tutti o lati essendo quadrato, questo è rettangolare quindi ha solo 2 posizioni utili. Unica pecca secondo me è il suo montaggio davvero scomodissimo, si poggia il dissipatore sulla cpu poi si capovolge la mobo e nel frattempo avvitare con delle minuscole viti.. bisognerebbe migliorarlo e magari aggiungere qualche ricambio dentro la confezione visto il prezzo..

There is a lot of confusion out there regarding AM5 processors and the higher temps being seen by people, regardless of the cooling solution they use.Noctua are the kings of air cooling in a lot of regards, and I use their products in almost all of my air cooled builds. I recently converted a tower mATX build into a rack mounted chassis so I could free up some desk space. Thus I needed a low profile cooling solution to cool my 7600X since the chassis I built in was only 2U. I obviously went with a Noctua solution, the Noctua NH-L9a-AM5.The server is used to run a Minecraft and Valheim server simultaneously, so there is always some load on the processor even when nobody is actively logged into either server.Temps at "idle" are usually around 60-65C, with spikes going as high as 95-100C. However those higher temperatures are only spikes, with the processor generally settling around 65-75C.The way these AM5 processors work is that they will ramp up power and clock speeds until they hit ~95C under a load, and then scale back so as to not ever go over that thermal maximum and cause damage the processor. It will go as fast as it can without going beyond that ~95C mark. So in a sense, the AM5 processors will fight against the cooling solution in order to get you the most performance without damaging the processor. This leads to higher idle and load temperatures.Some of this can be artificially controlled using BIOS/UEFI settings to limit what kind of temperature target you want to hit. Some of these options may vary depending on your motherboard manufacturer.However, the Noctua NH-L9a-AM5 is not doing a "bad job" if you are seeing higher than "normal" temperatures (i.e. temperatures you saw with AM4), as some reviewers would have you believe. The processor will be adjusting its power consumption and clock speeds so that it gives you the most performance that the Noctua NH-L9a-AM5 (or any cooler) can handle, unless you make changes to the default behavior of the processor manually. THAT is why people are seeing idle and load temps between 65-100C.All in all, I am happy with the Noctua NH-L9a-AM5's ability to cool my 7600X in such a small space with limited airflow. I did swap out the included low-profile fan for a Noctua NF-A9 to give it a little more fan power, but I can't really tell the difference in temps between that and the included fan.
