Compare: AG400 BK vs NH-D15

Design and Aesthetics:

AG400 BK

The AG400 series is a single tower 120mm CPU cooler that built upon DeepCool's legacy products but was stripped down for a streamlined and efficient package. It has a simple and clean design, with an aluminum tower and a single 120mm fan. This cooler comes in a variety of colors including black and white, so it matches most computer setups. Additionally, this cooler has RGB lighting which may fit for setups with a RGB focus.

NH-D15

The NH-D15 features a dual-tower design with two large aluminum heatsinks and a pair of Noctua's 140mm NF-A15 PWM fans. The cooler's design allows for superior heat dissipation, making it capable of handling even the most demanding processors. Aesthetically, this version of the NH-D15 maintains Noctua's signature beige and brown color scheme, reflecting the brand's reputation for quality and performance.

Install Notes:

AG400 BK

This cooler is moderately difficult to install and is more difficult than other DeepCool cooler installations. For AMD CPU's, the mounting setup can be given that the cooler doesn't secure through holes but rather through notches. For this reason, keeping the backplate flush against the motherboard while also keeping the install components in line may prove to be difficult and may require a second pair of hands. This also has a very similar installation to the AK400.

NH-D15

The NH-D15 features Noctua's SecuFirm2 mounting system, ensuring compatibility with numerous Intel and AMD sockets. The installation process is made easy with the help of clear instructions and top-notch components. Additionally, Noctua includes a tube of their high-quality NT-H1 thermal compound for optimal heat transfer between the CPU and heatsink. However, the cooler's large size may make it challenging to maneuver around when installed within the case.

Cooling Performance:

AG400 BK

It's designed to work with a wide range of modern CPU sockets and is able to dissipate heat quickly and efficiently. Although this cooler doesn't push out the best cooling performance, it does well for its size with performance slightly below the Noctua NH-U12S Redux. For this reason, this cooler is best for CPUs that need a moderate cooling solution.

NH-D15

The performance of the NH-D15 is exceptional due to its six heat pipes that efficiently transfer heat away from the CPU and into the large fin arrays of the heatsinks. It is suitable for a wide range of processors, from mainstream CPUs to high-end models with high TDPs. The cooler can handle high levels of overclocking and provides reliable cooling under demanding situations, making it a popular choice among enthusiasts. If this cooler can't handle the CPU's heat, then you will have to move to AIO coolers.

Noise Performance:

AG400 BK

This cooler has an above average noise profile, making it louder than most comparable air coolers. This means that you might experience more noise while your PC is running, which could be a drawback if you're sensitive to noise or prefer a quiet workspace. If having a quiet PC setup is important to you, it's worth considering other coolers with better noise profiles.

NH-D15

One of the standout features of the NH-D15 is its quiet operation relative to its performance. The two included 140mm NF-A15 PWM fans are designed for optimal airflow and low noise levels. Noctua fans are well-known for their excellent acoustic performance, and the NH-D15 is no exception. Users can expect quiet cooling even during intense workloads or gaming sessions. Additionally, the Low-Noise Adaptors (LNA) connectors included can be used to reduce the fan's speed, further reducing the cooler's noise.

Summary:

AG400 BK

The AG400 is an excellent choice to upgrade their CPU cooling solution. It has a sleek design with ARGB capabilities, helping create that look that sets you apart. However, this cooler isn't the most powerful cooling solution so it may not be best for all CPU's and it runs on the louder side. Overall, there is enough that sets this cooler apart that makes this cooler worth considering.

NH-D15

The NH-D15 is a dual-tower cooler with two aluminum heatsinks and a pair of Noctua's 140mm NF-A15 PWM fans, ensuring superior heat dissipation for a wide range of processors, even those with high TDPs. Its six heat pipes efficiently transfer heat, making it suitable for high levels of overclocking and demanding situations. With its signature beige and brown color scheme, the NH-D15 is not only known for its performance but also its quiet operation, thanks to the fans' design and included Low-Noise Adaptors for further noise reduction during intense workloads or gaming sessions.
