Compare: iCUE H100i Elite Capellix vs NH-D15 G2

Design and Aesthetics:

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.

NH-D15 G2

This cooler is quite large and showcases Noctua's signature design, appealing to diehard PC builders who don't want to compromise on cooling performance. The NH-D15 G2 closely resembles the previous generation, with a few updates. This version features eight heat pipes and offset depths on the two heatsinks

Install Notes:

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.

NH-D15 G2

The NH-D15 G2 retains the same installation design as its predecessor, with the addition of a new bracket that allows for offset mounting on AM5 CPUs. The installation process is straightforward, guided by clear instructions that adhere to industry standards for top-tier coolers. However, the cooler's large size may pose challenges when maneuvering it within the case.

Cooling Performance:

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.

NH-D15 G2

The Noctua's NH-D15 G2 cooler is hard to beat in terms of cooling performance, even outperforming AIOs from various other brands—a result expected given its larger size. However, when compared to the previous generation, its performance is on par, offering little improvement.

Noise Performance:

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.

NH-D15 G2

Compared to the average cooler, the Noctua NH-D15 G2 is louder than most on the market. However, when performance is evaluated on a noise-normalized basis, this cooler is tough to beat, offering excellent cooling for a given noise level. This means you can keep your cooler quiet when needed, while still having the headroom to increase the speed for enhanced cooling performance.

Summary:

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.

NH-D15 G2

The Noctua NH-D15 G2 retains the familiar installation design of its predecessor, with the addition of a new bracket for offset mounting on AM5 CPUs. While its large size may make installation a bit challenging, the process is straightforward, with clear instructions that meet industry standards. The cooler's substantial size is matched by its performance, offering exceptional cooling that even surpasses many AIOs from other brands. Although its performance is on par with the previous generation, the NH-D15 G2 still delivers excellent cooling, particularly when considering noise levels. Despite being louder than the average cooler, it excels in noise-normalized performance, allowing users to maintain quiet operation while having the flexibility to ramp up speed for maximum cooling when needed.
