Noctua NH-L9a-AM4, Quiet High-Performance Low-Profile CPU Cooler

After getting poor cooling with the stock AMD cooler on Ryzen 1400 and 3600, I opted for this to fit within my mid-sized case and keep the power draw low. A second PC running a 5600G also runs absolutely fine with it but for a bigger CPU or in a case with a hot GPU, I went for the awesome Noctua NH-U12S redux. This is very quiet, miles better than the poor AMD cooler. If you need a low profile cooler that's easy to install (thank you Noctua), this is just the ticket.

The Asrock Deskmini A300 is a very small desktop computer and comes with a stock cooler. The Stock cooler does its job but is a little noisier than most people would prefer. The Noctua NH-L9A-AMA is the recommended cooler for these small factor computers. Asrock deskmini owners are familiar with opening up and configuring the computer so it shouldn't be difficult to fit the cooler. I would say it is fairly easy if the instructions are followed and the job isn't rushed. I fitted the included low noise adaptor because my computing needs are small and i don't do gaming; thus the computer is never going to get very hot. After reassembly, the difference between old and new was a delight. The computer, which is I have vertically-positioned, is now silent. If I stick my ear right next to the exhaust side I can hear a very slight hum. otherwise - nothing. The temperature (linux 'sensors') is stable at around 30°C, slightly lower than previously. All-in-all a great buy at under £35 and I wish I had done this much earlier.

Having read earlier reviews before purchase, I'd read how this item could be a little difficult to mount on the CPU. However, the design has been changed with the bars already fixed to align with the MB mounting holes. It was thus simple to install. I placed the cooler module upside down on bubble wrap (to protect the fan) and after applying the heat-sink compound onto the base of the cooler rather than the top of the CPU, I turned the mother board over and it was easy to locate the mounting holes to the arms of the device. Lowering the MB gently onto the cooler, it was then easy to screw the cooler against the CPU, thus providing a good seal. It works very well and, even under high CPU loads, is remarkably quiet. Thoroughly recommended!

I bought it as a replacement for my loud Water Cooling loop, which was getting old in the tooth and wanted something more low profile. So decided to bite the bullet and get this, which on instalment, it was rather easy though can be fiddly with the screws. My one complete though is that my thermals are actually WORSE now than they were with my Water Loop, now I'm getting above 76c on idle, which isn't perfect especially when I start using software like Blender and such. Overall, it's an okay cooler IF you plan to use it for basic things like building a media PC, would not recommend for Gaming or Workstation rigs unless you have really good airflow in your case.

Noctua NH-L9a-AM4 is outstanding! Perfect low-profile cooler for AMD AM4 builds. Extremely quiet, yet keeps my CPU temperatures low even under load. Easy to install and incredibly reliable. Ideal for compact PCs without sacrificing cooling performance. Highly recommend!

Easy to fit ,bought for htpc build , Ryzen 5 3600 , 550 atx power supply, 8gig ram ,2 gig card with no fan,2 x SSD's, Ubuntu with Plex keeps board / and all parts processor temp down below 45 degrees on normal fan settings . pretty quiet as well

Comes in a very nicely presented box, with a metal case badge, cable to reduce speed, tube of thermal paste, rear mount plate and extra screws in case you want to replace the stock fan with a thicker one. Very weighty and well machined, it all seems very good quality. I fitted this to a Ryzen 3 2200g on an AsRock AB350 Gaming ITX motherboard. It was a little awkward as you have to screw the heatsink on from the underside, while holding it in place and keeping aligned. It's very well mounted though. Most temps seem similar to stock, but with much lower noise. I was always aware of the Wraith Stealth fan whereas in the same situations this is silent. When pushed the fan is louder but still acceptable, and quieter than the Stealth. With a GPU overclock to 1500MHz and gaming on GTA Online the fan seems to get to about 80% speed, so probably has a bit more potential. I'm using this is a very compact case with restricted airflow so my temps are higher than average, hitting about 80C in games that push the 2200g.

As always, another great product from Noctua. I have a machine with a Ryzen 5 3400G processor, which until I bought this Noctua cooler, I was using with the stock "Wraith Spire" cooler. It was doing adequate amounts of cooling, but it was really noisy- at least for my needs as a living room PC. I was dubious as to whether this Noctua would make much difference. Some random posts I'd found online suggested that the noise profile of the fans of the Noctua and the stock cooler weren't too dissimilar. However I'm pleasantly surprised - It's made a huge difference. My stock fan would ramp up and down in speed all the time, whereas this is a constant low noise, which is much more pleasing! Plus it's keeping CPU temps in the 30-40's which is awesome!

You get what you paid for. Price is much cheaper on Amazon compared to other sources

Ich habe den Noctua L9a mittlerweile schon dreimal für verschiedene Systeme gekauft und bin jedes Mal aufs Neue überzeugt. Als jemand, der früher bei einem Mitbewerber im Bereich Kühltechnik gearbeitet hat, kann ich sagen: Noctua setzt seit jeher den Standard. Die Qualität und die Leistung dieses Kühlers sind einfach herausragend. Der L9a ist besonders für kompakte Builds oder HTPCs ideal. Trotz seiner geringen Größe liefert er eine sehr gute Kühlleistung und ist dabei unglaublich leise. Der Einbau gestaltet sich dank der klaren Anleitung und der durchdachten Konstruktion problemlos – auch in engen Gehäusen. Was mich besonders beeindruckt, ist die leise Laufweise. Selbst bei längeren Belastungen bleibt der Kühler nahezu unhörbar. Als jemand, der viele Kühler verschiedener Hersteller getestet und eigene mitentwickelt hat, kann ich sagen, dass Noctua immer der Maßstab für hochwertige und zuverlässige Kühlungstechnologie war und auch heute noch ist. Fazit: Der Noctua L9a ist ein exzellenter Kühler, der in jeder Hinsicht überzeugt. Ich werde ihn auch in Zukunft wieder wählen und kann ihn jedem empfehlen, der auf Qualität, Leistung und geringe Lautstärke setzt!

スリムタイプのPCを自作する際に使用。 スリムタイプだと冷却性能が良いファンだと大きさ的に入らないことが多いためこのファンを使用させていただきました。 そこまでの騒音は感じず、満足して使用させていただいてます。 他のパーツとの干渉を気にする必要がないため、初心者にもお勧めです。 ただ少し値段が高いため、フルタワーPCを自作するならほかのファンでいいと思います。

Livraison rapide et professionnels, la marque paraît être de confiance, le ventilateur radiateur est vendu dans un coffret de qualité avec une pipette de pâte thermique, un adaptateur 4 pin plus gros, et tout le matériel nécessaire à l'installation, qui est simple et efficace. Grâce à ce produit j'ai remplacé le ventilateur d'origine de mon barebone A300. Il le refroidi plus efficacement et beaucoup moins bruyamment, je conseille fortement !

Tyst och med bra kylning för en kompakt bygge med am4 socker och ryzen 5600Gt
