Compare: NH-L9x65 vs Liquid Freezer III 240

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.

Liquid Freezer III 240

This cooler showcases a sleek, symmetrical design with a modern aesthetic. While this model doesn’t include RGB lighting, there are versions available that do, allowing you to choose based on your style preferences. Overall, it adds a clean, contemporary look to your PC 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.

Liquid Freezer III 240

The Arctic Freezer III 240 retains the easy installation features of its predecessor while offering added convenience. What sets this cooler apart is its pre-installed fans on the radiator, simplifying the setup compared to other all-in-one (AIO) coolers. The detachable CPU mounting bracket further enhances the installation process by eliminating interference from aesthetic components. However, attaching the control cable to the motherboard can be challenging once the cooler is mounted. To avoid this, it’s advisable to connect the cable to the motherboard before installing the cooler.

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.

Liquid Freezer III 240

The Arctic Freezer III 240 offers some performance improvements over its predecessor, the Arctic Freezer 240, but this comes with increased noise. Relative to other coolers in it's weight class, this cooler outperforms most.

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.

Liquid Freezer III 240

The Arctic Freezer III 240 has a more powerful pump that has the potential to be quite audible. Since our testing was conducted with the AIO pump running at 100% speed, lowering the pump speed during less demanding tasks can help reduce noise levels without sacrificing too much performance.

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.

Liquid Freezer III 240

The Arctic Freezer III retains its user-friendly installation design, featuring pre-attached radiator fans and a detachable CPU mounting bracket for simpler setup. However, connecting the control cable can be challenging once the cooler is installed, so it's best to attach it beforehand. The cooler sports a modern design, with some versions offering RGB lighting for added customization. While it boasts aesthetic improvements and lower noise levels compared to standard coolers and its predecessor, the Arctic Freezer 240, the Arctic Freezer III 240 delivers average performance and struggles to effectively cool high-core CPUs under heavy workloads.
