A Quiet, Almost Silent Cooler
I don’t write reviews often but I felt this cooler was worthy of one. It arrived in good condition in very well designed packaging. There were three different instruction manuals for different socket types respectively, thermal paste was also included! Mounting system was very simple and effective, screwdriver included. Fan is very quiet even without low noise adapter, and almost silent with the adapter! Temperatures are good, with my i5 3570K @4Ghz (Boost to 4.4GHz), around 30C idle and up to ~65C under load (although this is with low noise adapter). My only gripe is that the fan mounting wires (if you choose to switch to high clearance layout) can be difficult to attach without damaging the heatsink fins.All in all a great cooler and well worth the money!

Brilliant low profile Cooler
Honestly so glad I purchased this CPU cooler. It has been a night and day difference compared to my old stock cooler that came with the case. It was starting to get too noisy to bare and wasn’t sufficient enough to keep my CPU cool aswell. Just on PC start up the fan would run at about 1950 RPM with an average CPU temperature of about 65°C.With this Noctua cooler, it is now much quieter, running at about 650-700 RPM on start up and it literally halfed the CPU temperature which is now running at about 32°C. Made such a clear difference and would highly recommend.

Amazing!
I bought this to replace a corsair h100i v2 to save space and weight. It’s a he’ll of a lot quieter. It’s barely audible and keeps temps low. I haven’t felt this good about a purchase in a long time. Obviously we’ll made and quality parts. Well worth it.

I picked up this cooler to replace an H80i v2 which failed on me after just a few months in my ITX 9700K Solidworks PC build. I figured I’d go back to old reliable air cooling since it seems like other folks have had similar issues with that particular AIO.First of all, the packaging design for this cooler deserves an award. I’ve bought Noctua fans before, but this was my first CPU cooler from them – all the packaging (aside from a couple plastic bags for mounting hardware) is beautifully folded cardboard that snugly keeps everything in its proper place. It would have been easy for Noctua to just make a few styrofoam molds to hold this thing, but they took the time to come up with this lovely origami-esque solution that is functional and environmentally friendly. Nice job guys!All of the hardware is great quality – mostly metal aside from a couple plastic spacers. The fan comes pre-installed in the most compact configuration (you can put it on top for better performance, but it might not fit in many ITX builds) and there are several instruction booklets (again, nice quality, for the different chipsets. Compared to other air coolers I’ve used, the mounting for this is a breeze – the LGA115X backplate has the feed-through standoffs press-fit so you just sort of pop it through the back and the rest of the installation is quite straightforward. If you’re using this for AMD or a less common Intel chipset, the installation is a little more involved but probably not too bad. Additionally, there is a little metal Noctua decal “sticker” included which is the nicest logo swag I’ve ever gotten with a PC component (and I have built some very high end PCs!).The build is in a Silverstone SG13 case with a Silverstone SFX PSU. The CPU is an Intel 9700K running at stock settings with 2 sticks of 16GB Crucial 2666 spreaderless RAM. There is about 3/16″ clearance between the top of this cooler and the PSU (PSU is flipped such that the intake fan is directly over the CPU heatsink) and about 1/8″ between the CPU fan and the RAM. I put an additional Noctua 120mm fan on the front of the case for additional airflow.As far as cooling performance goes, I was very pleasantly surprised. Keep in mind, this is not a gaming build. This is a Solidworks PC that I use for moderate CAD work (about 1500 parts in my most complex assembly). Probably most importantly, when under typical loads, there is not a big, power-hungry GPU dumping a bunch of heat into my little ITX box – there is a tiny little P400 workstation card which is mostly there to provide multi-monitor support. That said, at an ambient temperature of nearly 90F (in my top floor California apartment with no AC) I was able to run the Solidworks benchmark as well as mess around with my largest assembly without every seeing a core temperature go above 70C. All the while, core clocks never dropped below 4700MHz. When I threw Prime95 at it, The core clocks evened out to around 4400MHz (130W power draw according to Core Temp) and temperatures hovered in the low 70’s with the max I ever saw at 76C. Again, this is in a stuffy 90F ambient apartment.I can’t provide measurements for noise levels, but I will say that, under moderate loading with all BIOS fan settings set to “Standard” this cooler cools my 9700K almost silently. Yes, when Prime95 is running and all 8 cores are under 100% load, it gets a bit louder, but not nearly as loud as some blower GPUs I’ve heard in gaming builds. In an office setting where the ambient temperature will be almost 10C below what I was testing at, I would never worry about my CPU overheating or the fans blowing so loudly that they bother my neighbors.This product receives my wholehearted recommendation – great job Noctua!

Prodotto veramente valido, adatto per case di dimensioni medie e piccole. Il rumore della ventola non si sente nemmeno a regime massimo di funzionamento. Le temperature sono ben controllate, montato sul nuovo socket 1200 per un i7-10700K, raggiunge una temperatura massima che fluttua i 70 e gli 80 gradi mantenendo il clock dinamico del turbo boost technology.Utilizzando il processore al massimo del boost fisso a 5.1GHz, le temperature salgono oltre i 90°, in tal caso è meglio montare il modello NH-U12A o NH-U12S che sono piu’ performanti.Il montaggio è semplice, ma serve un po’ di manualità. La parte più complessa è il fissaggio del radiatore ai supporti, ci vuole un po’ di pazienza per centrare e fissare le viti di entrambi i lati.

I’ve been using Noctua coolers and fans for years, and the NH-L12S 70mm Low Profile CPU Cooler is yet another excellent addition to my NAS build. I chose this cooler primarily for its low-profile design, which fits perfectly into my custom 3D-printed NAS case, and of course, Noctua’s reputation for high-quality and quiet components.Performance:Cooling Efficiency: The NH-L12S performs just as expected – great cooling with quiet operation. For the best results, I recommend replacing the thermal paste that comes with the cooler with a PTM7950 thermal pad, as it further enhances thermal conductivity.Noise Level: The 120mm PWM fan is incredibly quiet. In fact, my hard drives are louder than this cooler. It truly lives up to Noctua’s promise of silent operation.Installation:Mounting Process: The installation was smooth, with clear, step-by-step instructions. I had no issues mounting it on my 1700 LGA socket, and it fit perfectly into the build.Clearance: There were no clearance issues with other components (like RAM, GPU, or PSU). The cooler’s ability to rotate and install in different orientations ensures flexibility in compact builds.Build Quality:Premium Design: As expected, Noctua’s materials and design are top-notch. The cooler feels sturdy, and the fan quality is consistent with the brand’s reputation.Packaging:Protection During Delivery: The packaging was more than adequate to protect the cooler during shipping.Included Accessories: The cooler includes all necessary mounting brackets and installation kits for both AMD and Intel setups, making it versatile for various builds.Value for Money:For anyone looking for a reliable, quiet, and efficient cooler, the Noctua NH-L12S is a proven solution. Despite its price, the quality and performance justify the cost.Final Verdict:I highly recommend the Noctua NH-L12S for anyone building a compact system or NAS. It fits perfectly, performs efficiently, and keeps your CPU cool without making any noise. As always, Noctua delivers exceptional products that are built to last.
