With a height of only 65mm, the cooler is compatible with a wide range of PC cases, including mini-ITX and HTPC builds. Aesthetically, the NH-L9x65 maintains Noctua's signature beige and brown color scheme, reflecting the brand's reputation for quality and performance.

iCUE H100i Elite Capellix

The 240mm RGB Fan AIO Liquid Cooler features two 120mm RGB fans. Complemented by its sleek black radiator and tubing, this cooler effortlessly fits into your setup while offering customizable brilliance that complements other components. Thanks to iCUE compatibility, it easily syncs with fellow Corsair RGB products, enabling personalized color schemes and effects, all while maintaining top-tier cooling performance. For those seeking a balanced blend of style and cooling prowess, this cooler stands as a compelling choice.

Install Notes:

NH-L9x65

This cooler is designed to be a typical Noctua cooler installation, which is easy to do and rather straightforward. This means that if you're new to installing a CPU cooler, there is little room to make a mistake. For AMD is uses the original AMD backplate. Only downside to the Noctua installation is that the cooler may stick to your CPU and given how the screws are setup, you can't slide the cooler off the CPU like other brands.

iCUE H100i Elite Capellix

This cooler is relatively easy to install and is a typical iCUE AIO install. This cooler has a standard AIO installation where you must screw the fans onto the radiator. In regards to the pump installation, this AIO has four screws that go into the backplate, where the pump can then be placed and secured with screw caps. To swap the cooler for different CPU mounting systems (AMD/Intel) is relativly easy and doesn't require any screws. However, the corsair logo is secured with four hex screws, so it might require additional work to get the logo in the proper direction. When it comes to RGB setup, this AIO requires the use of the Corsair iCUE Commander CORE RGB HUB. Additionally, the heat pipes pivot at the pump, which allows for a more versatile installation.

Cooling Performance:

NH-L9x65

The performance of the NH-L9x65 is suitable for most mainstream CPUs and everyday tasks. It has four heat pipes that efficiently transfer heat away from the CPU to the heatsink. While the cooler may not be the best choice for high-end CPUs with high TDPs or extreme overclocking scenarios, it provides adequate cooling for lower TDP CPUs, especially in small form factor builds with limited space.

iCUE H100i Elite Capellix

The iCUE H100i Elite Capellix provides excellent cooling performance that rivals top-tier air coolers such as the NH-D15, this cooler stands out as a cooler that can handle the heat. Perfectly tailored for setups in looking for remarkable cooling efficiency without compromising on noise levels, it does so without the unwieldy dimensions of some of the larger air cooling solutions.

Noise Performance:

NH-L9x65

The 92mm NF-A9x14 PWM fan included with the NH-L9x65 is designed for quiet operation while maintaining good airflow for its size. Noctua fans are well-known for their excellent acoustic performance, and the NH-L9x65 is no exception. Users can expect quiet cooling even during low workloads, however due to it's limited cooling abilities, it may have to run louder moderate workloads or gaming sessions.

iCUE H100i Elite Capellix

This cooler offers impressive noise levels in proportion to its cooling performance. However, owing to its dual-fan setup, it can produce audible noise. This aspect should mainly concern those who plan on pushing their CPU to overclocked limits.

Summary:

NH-L9x65

The Noctua NH-L9x65 is a compact and efficient air cooler that's well-suited for small form factor builds and systems with limited space. Its low-profile design, adequate cooling performance, and quiet operation make it an attractive option for those looking for a space-saving and reliable cooling solution.

iCUE H100i Elite Capellix

This cooler is easily installed with standard iCUE AIO procedures for fans and pump. CPU swaps are straightforward, but adjusting the logo may need extra effort. The 240mm RGB Fan AIO Liquid Cooler seamlessly integrates into setups, with two captivating 120mm RGB fans and a sleek black radiator, offering customizable brilliance via iCUE compatibility. It matches top-tier air coolers' performance, ideal for efficient cooling without noise worries. Audible noise from the dual-fan setup is mainly relevant for aggressive CPU overclocking.
