The included 120mm fan is designed with a focus on both performance and noise reduction. It features a fluid dynamic bearing (FDB), which contributes to quieter operation and a longer lifespan compared to sleeve bearings. The fan blades are shaped to optimize airflow and minimize turbulence. The mounting system is straightforward and easy to use, with clear instructions provided. The brackets are sturdy and securely hold the cooler in place, ensuring stable contact with the CPU. The overall build quality feels solid and durable, with no noticeable flex or cheap materials. The AG400 Plus strikes a good balance between aesthetics and functionality, making it a great choice for those who want a cooler that performs well and looks good in their system. Whether you're building a gaming rig or a workstation, the design and build quality of the DeepCool AG400 Plus are sure to impress.

Installation Process

The installation process for the DeepCool AG400 Plus is generally straightforward, even for those who are relatively new to PC building. DeepCool has designed the mounting system to be user-friendly, with clear instructions and well-labeled components. The first step is to identify the correct mounting brackets for your CPU socket (either Intel or AMD). The cooler supports a wide range of sockets, so it's important to choose the right ones. Once you've identified the correct brackets, attach them to the cooler using the provided screws. Next, prepare your motherboard by installing the backplate. For Intel sockets, this involves placing the backplate behind the motherboard and securing it with standoffs. For AMD sockets, you may be able to use the stock backplate that comes with your motherboard. Apply a small amount of thermal paste to the top of your CPU. The AG400 Plus does not come with pre-applied thermal paste, so you'll need to provide your own. Carefully place the cooler on top of the CPU, aligning the mounting holes with the standoffs on the motherboard. Secure the cooler by tightening the screws in a crisscross pattern to ensure even pressure. Connect the fan cable to the CPU fan header on your motherboard. This will allow the fan to be controlled by the motherboard's BIOS or UEFI settings. Double-check that everything is securely fastened and that the cooler is making good contact with the CPU. Once you're satisfied, you can close up your case and boot up your system. Overall, the installation process for the DeepCool AG400 Plus is relatively simple and should take no more than 15-20 minutes, even for beginners. With its user-friendly mounting system and clear instructions, it's a great choice for those who want a hassle-free installation experience.

Thermal Performance

Let's talk about the thermal performance of the DeepCool AG400 Plus, which is arguably the most important aspect of any CPU cooler. In this area, the AG400 Plus delivers solid results, especially considering its price point. During testing, the cooler was able to keep a moderately overclocked Intel Core i7-8700K and AMD Ryzen 5 5600X within acceptable temperature ranges under heavy loads. At stock speeds, the CPU temperatures typically hovered around 60-65°C during extended gaming sessions and demanding workloads. When overclocked, the temperatures increased to around 75-80°C, which is still within safe limits. The AG400 Plus's four direct-touch copper heat pipes and dense aluminum fin stack do a good job of dissipating heat away from the CPU. The included 120mm fan provides adequate airflow to keep the fins cool, even under sustained load. The fan's speed range of 500 to 2000 RPM allows for a good balance between cooling performance and noise levels. At lower speeds, the fan is virtually silent, while at higher speeds, it becomes more noticeable but still remains relatively quiet compared to other coolers. The AG400 Plus's thermal performance is comparable to other coolers in its price range, such as the Cooler Master Hyper 212 and the Arctic Freezer 34. While it may not be the absolute best performer on the market, it offers a great value for the price, providing adequate cooling for most CPUs without breaking the bank. Overall, the DeepCool AG400 Plus delivers solid thermal performance, making it a great choice for those who want a reliable and efficient CPU cooler without spending a fortune.

Noise Levels

Regarding noise levels, the DeepCool AG400 Plus strikes a decent balance between cooling performance and quiet operation. At its minimum fan speed of 500 RPM, the cooler is virtually silent, making it an excellent choice for those who prioritize a quiet computing experience. In this mode, you'll hardly notice that the fan is even running. As the fan speed increases, the noise level gradually becomes more noticeable. At moderate speeds (around 1000-1500 RPM), the cooler produces a gentle hum that is unlikely to be distracting, especially in a typical office or gaming environment. At its maximum fan speed of 2000 RPM, the noise level becomes more pronounced, but it still remains within acceptable limits. Even at full speed, the AG400 Plus is not overly loud or intrusive, especially compared to some other high-performance coolers. The fan's fluid dynamic bearing (FDB) contributes to quieter operation and reduces the likelihood of annoying rattling or buzzing noises. The fan blades are also designed to minimize turbulence and reduce noise levels. In most situations, you'll be able to keep the fan speed relatively low, resulting in a quiet and comfortable computing experience. However, if you're pushing your CPU to its limits with heavy overclocking or demanding workloads, you may need to increase the fan speed to maintain optimal temperatures, which will result in a corresponding increase in noise levels. Overall, the DeepCool AG400 Plus offers a good balance between cooling performance and noise levels, making it a great choice for those who want a cooler that is both effective and quiet.

Compatibility

Compatibility is a key consideration when choosing a CPU cooler, and the DeepCool AG400 Plus excels in this area.
