  • 1x NF-A9x14 low profile PWM fan included
  • separate AM4 bracket

noctua-nh-l9i-chromax-blackCheck Today's Price of Noctua NH-L9i chromax.Black ➜➜

The CPU cooler’s height, including the fan, is just 37mm, which is insane. The footprint covers 95×95 mm.

What does that mean?

Well, it will fit any mini-ITX motherboards and will not block the PCIe slot or overhang the RAM modules due to its minimal footprint. The minimal height ensures it fits into even the smallest PC cases with tight spaces.

Despite being low profile, it provides enough cooling performance to give you stable gaming or working experience without thermal throttling.


It won’t rival the other big Noctua coolers, but it isn’t supposed to be at a fraction of the size. As a result, it will not be capable of preventing overclocked CPUs from thermal throttling.

The Noctua NH-L9i chromax.Black is designed especially for Intel LGA 115x motherboards, but you can also get an AM4 mounting bracket to use with AMD CPUs.

noctua-nh-l12sCheck Today's Price of Noctua NH-L12S ➜➜

The Noctua NH-L12S is a successor to the NH-L12, with improved efficiency, flexibility, and compatibility. Let’s discuss them.

The flexibility of this cooler is excellent. Unlike most low-profile coolers, which provide almost no flexibility, here you get a lot. The heatsink is a C-shaped one so that you can mount the fan either up or down.

If you install the fan at the top, you get up to 48mm of RAM clearance, a lot for small motherboards. If the fan is at the bottom, the height of the entire module reduces to just 70mm, making it suitable for most ITX cases or HTPCs.

Here’s a complete guide on how to fix CPU fan not spinning.

The fan in question here is the NF-A12x15 model, a silent and slim 120mm fan with PWM support. It is an improvement over the 92mm fan on the NH-L12, providing higher airflow and higher efficiency.

Lastly, the flexibility of the Noctua NH-L12S makes it compatible with most cases and motherboards, including the mini-ITX category. The SecuFirm2 mounting system and the NT-H1 thermal compound stay here, too, just like other CPU coolers in this list.

  • »high efficiency
  • »superb flexibility
  • »excellent thermal management
  • »low noise
  • »might not go well with RGB color schemes

11. Noctua NH-L9x65 SE-AM4

The Noctua NH-L9x65 SE-AM4 is another low-profile offering from Noctua specially designed for the AM4 platform.

Some of the highlights of the Noctua NH-L9x65 SE-AM4:

  • low profile CPU cooler for AMD AM4 socket
  • 1x NF-A9x14 PWM 92mm fan included
  • 65mm tall
  • 95x95mm footprint
  • NT-H1 thermal compound applied

noctua-nh-l9x65Check Today's Price of Noctua NH-L9x65 ➜➜

The cooler is a low-profile one and shares a lot with the NH-L9i chromax.Black mentioned above. The main noticeable difference is the color scheme, as it goes for a traditional Noctua brown and beige color scheme.

The footprint is the same with 95x95mm, while the height increases to 65mm. The heatsink of the Noctua NH-L9x65 SE-AM4 is relatively thicker than the former model, making it possess more surface area and hence be more efficient.

Another main difference is the platform. The NH-L9i is designed for Intel LGA 115x sockets, while the Noctua NH-L9x65 SE-AM4 aims for the AMD AM4 platform. So it will provide better compatibility and clearance on AM4 motherboards out of the box, including ITX ones.

A 92mm NF-A9x14 PWM fan is included, which does a decent job of providing airflow. You also get the easy-to-install SecuFirm2 mounting system and pre-applied thermal compound.

Just don’t use it in an overclocked CPU or any CPU with more than 95W TDP,  and you will get the best air cooling performance possible in this small low profile cooler.

Check out the easiest way to fix CPU cooler not lighting up.

  • »efficient cooling
  • »highly compact
  • »enough RAM, heatsink, PCIe clearance on ITX motherboards
