Compare: NH-L9x65 vs Frost Spirit 140

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.

Frost Spirit 140

The Frost Spirit looks very similar to the Frost commander and is a sleek CPU cooler with a design reminiscent of the Peerless Assassin 120. This cooler features a dual-tower heatsink with 4 large heat pipes with the heat pipe ends are hidden from view. Sporting gray and silver tones, the Thermalright logo shows on the top of the heatsink. Despite its larger radiator, the Frost Spirit uses a single 120mm fan in front and a 140mm fan between the heatsinks, giving it a distinct, asymmetrical look.

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.

Frost Spirit 140

The cooler installation is quite similar to Noctua's easy setup and is identical to the Frost Commander's setup. However, during installation, securing the fans to the heatsink requires more effort (relative to the Phantom Spirit or Peerless Assassin), which is due to the metal securing the fans requiring much more effort to place. For this reason, it's also a lot easier to slightly bend the heatsink fins, but this can be fixed by bending it back with a credit card.

Additionally, like Noctua coolers, the Frost Spirit faces challenges in uninstalling when trying to break the thermal paste seal between the cooler and CPU, as it doesn't easily slide or twist off. This can be an issue if the thermal paste forms a strong bond.

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.

Frost Spirit 140

The Frost Spirit delivers impressive performance for its size, rivaling Noctua's offerings. Capable of cooling some of the more powerful CPUs without being overly bulky, this cooler can also manage overclocking for specific CPUs. As a result, the Frost Spirit is a strong contender for a wide variety of computer setups.

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.

Frost Spirit 140

The Frost Spirit excels in providing an impressively silent operation, setting it apart from its sibling, the Frost Commander 140. The lower fan RPM of this cooler plays a substantial role in reducing noise levels when compared to the Frost Commander. Furthermore, it boasts a noise profile that can be likened to that of the NH-D15, making it an optimal selection for individuals who prioritize a noise-free environment.

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.

Frost Spirit 140

The Frost Spirit CPU cooler offers a sleek design resembling the Frost Commander and Peerless Assassin 120. It requires extra effort to secure the fans to the heatsink due to the metal's firm placement. Despite its larger radiator, the Frost Spirit maintains a compact size with a single 120mm front fan and a 140mm fan between the heatsinks. It delivers impressive performance, rivaling Noctua's offerings, and is capable of effectively cooling powerful CPUs and managing overclocking. Notably, it stands out for its remarkably quiet operation, surpassing the noise levels of the Frost Commander 140, with a noise profile similar to the NH-D15. Overall, the Frost Spirit is a stylish, powerful, and quiet CPU cooler suitable for various computer setups.
