Compare: NH-L9x65 vs Dark Rock Pro 5 (Performance)

Design and Aesthetics:

NH-L9x65

The NH-L9x65 features a low-profile design with a slim aluminum heatsink and a 92mm NF-A9x14 PWM fan. 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.

Dark Rock Pro 5 (Performance)

This cooler features a sleek black design that stands out. The signature Be-Quiet fan adds a unique touch, breaking away from the cooler's boxy appearance. Additionally, the top of the cooler boasts a clean design, contributing to a polished and refined look for your setup.

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.

Dark Rock Pro 5 (Performance)

The Dark Rock Pro 5 marks a notable advancement over its predecessors, featuring a mounting system that aligns with those of most mainstream coolers. This iteration enhances the design by securing the mounting bracket directly to the cooler, a change from the prior generation. Fan installation sees improvements too; the front fan comes pre-attached, ensuring perfect alignment, while the middle fan is designed to slide in from the top, secured by the top mount instead of side brackets. These enhancements significantly improve the cooler's setup and performance compared to the previous generation. Additionally, given the option to change the power speed on the top of the cooler, the middle fan has a 5 pin connector to facilitate this functionality, which forces you to use their connection rather than direct control through the motherboard.

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.

Dark Rock Pro 5 (Performance)

There are two modes to this cooler, the performance mode and the quiet mode. The cooler selected covers the performance mode of the cooler. Overall, this cooler provides better cooling than the average cooler tested. However, this cooler get's puts to its limits when placed under high loads. With that in mind, if you're looking to place this cooler on a CPU that produces a lot of heat, you may want to consider other options.

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.

Dark Rock Pro 5 (Performance)

In regards to sound, this cooler is quieter than the average cooler between 60% fan speed and 90% fan speed. However as the fan approaches 100%, the noise level is more in line with what to expect from an average cooler.

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.

Dark Rock Pro 5 (Performance)

The Dark Rock Pro 5 features an improved mounting system and pre-attached fans for easier setup, with an option to adjust fan speed directly on the device. Its sleek black design and signature quiet fan contribute to both aesthetics and performance, offering enhanced cooling in both performance and quiet modes. Although it outperforms average coolers under moderate loads, it may struggle with high-heat CPUs. Noise levels are lower than average until the fan reaches full speed, where it aligns with typical cooler sounds.
