Noctua NH-L12Sx77, Low-Profile CPU Cooler (120mm, Brown)

This is my first Noctua product that I’ve purchased. And it didn’t disappoint. The 140mm liquid cooler that comes preinstalled on the NZXT H1 (V1) Small Form Factor ITX Case failed and I needed a new cooler to cool my Intel i9 10850K. Before the liquid cooler failed and was working properly, it would keep the cpu temps around 60-75C while gaming. This Noctua cooler dropped the temps to between 50-65C which is absolutely unreal from such a small cooler. I’m sure there are other coolers that can get similar performance or close to it for half the price, but honestly the quality of this product and with how quietly it does its job has made me overlook that. If you’re needing a small form factor cooler and only need to cool about 100w of cpu power, I can’t see any reason to not buy this cooler. Highly recommend.

This cooler works well enough for a small form factor 9700X build cranked up from 65W to 105W. If you have enough room for the fan on top of the heatsink then also take a look at other options. It's really compact with the fan under the heatsink and cools about as well.

I was using L9x65 (w/25mm Noctua fan) with ROG B660I and Intel 12400 but I just upgraded to 13700F. In fear of the ultra hot 13th gen CPU, I decided to also try out this new 120mm cooler.My original concern was that my previous cooler has a chunkier heatsink with a thicker fan (92mm x25mm) which was very effective and also extremely quiet with my fan policy. Will the newer cooler with 15mm thinner fan be able to do more cooling?The result is stunning. My SSD and RAM dropped 3 Celsius and 20 Celsius respectively while my new CPU (locked to 140w power draw) is around 10 Celsius cooler as well compared to 12400 previously running at only 70w power draw.

Got this after we were having heat issues with an old build, issues are gone now. Have converted the machine to a Linux box for playing with LLMs and it's rare that I get temps in the 60s, only after a few hours at load. Pretty great.

Bought this to replace a stock cooler and it dropped the temp 50 degrees. Took the machine from almost too hot to perfect. Added bonus, if you don't need the thin fan that comes with this get a thicker fan and improve cooling even more.

Was easy to install onto an ITX mobo for an AM5 processor. Decided to switch the fan to the top side. Its working well.

I don't overclock, I only wanted the quietest system since I share an office with someone. Running i5 12600kf @4.9GH and Quiet fan set up. I can barely hear the fan at all. The only thing I did differently was putting the fan on top instead of below. The fan did clear my RAM, but it was very tight. The rear 80mm fan had to be removed. The heatsink went right against it. Believe it or not, this is quieter than the NZXT AIO it replaced. Should've just gone with this in the first place.

If you have those requirements, this will be it.If your card is THICKER than > ~40-42mm do not get this cooler for the Fractal Terra.Cools my 7800X3D super well.I have a custom configured Blower - Style 4070ti Super 16gb VRAM.3-5 degree improvement from original NH-12 from Noctua (4-pipe version).NOTE: SWAP THE FAN’s DEFAULT CONFIGURATION FROM EXHAUST (STOCK) to INTAKE !! You will see an additional 1-3 C improvement in temperatures.
