Hey guys! Today, we're diving deep into the world of CPU coolers, specifically comparing the Deepcool AG400 and the AK400. If you're building a new PC or just looking to upgrade your current cooling solution, you've probably come across these two contenders. They're both popular, affordable, and promise to keep your CPU running cool under pressure. But which one is the right choice for you? Let's break it down and see what makes each of these coolers tick.
Deepcool AG400: A Solid Performer
The Deepcool AG400 is a single-tower air cooler designed to offer a balance of performance and affordability. It's aimed at users who want a step up from the stock cooler without breaking the bank. The AG400 features a dense array of aluminum fins, four direct-contact copper heat pipes, and a 120mm hydraulic bearing fan. This combination works to efficiently dissipate heat away from your CPU.
When it comes to installation, the AG400 is relatively straightforward. It supports a wide range of CPU sockets, including the latest Intel and AMD platforms, making it a versatile choice for various builds. The included mounting hardware is user-friendly, and the instructions are clear, so even novice builders should have no trouble getting it installed. The cooler's compact design also ensures it won't interfere with other components on your motherboard, such as RAM modules.
In terms of performance, the Deepcool AG400 delivers respectable cooling capabilities. It's capable of handling CPUs with TDPs (Thermal Design Power) up to around 140W, which means it's well-suited for most mainstream processors. During testing, the AG400 keeps temperatures under control, even when the CPU is under heavy load. The 120mm fan operates quietly, ensuring that your system remains relatively silent even during intense gaming sessions or demanding workloads. The fan's PWM (Pulse Width Modulation) control allows it to adjust its speed based on the CPU temperature, striking a good balance between cooling performance and noise levels. Overall, the AG400 is a solid performer that offers excellent value for its price.
Deepcool AK400: The Upgraded Option
The Deepcool AK400 can be seen as the slightly beefier brother of the AG400. While it shares a similar design philosophy, the AK400 boasts a few key upgrades that enhance its cooling capabilities. Like the AG400, it features a single-tower design with aluminum fins and direct-contact copper heat pipes. However, the AK400 typically includes a more efficient fan and potentially a slightly larger heatsink, contributing to improved thermal performance.
Installation of the AK400 is also quite simple, mirroring the user-friendly design of the AG400. It supports the same wide range of CPU sockets, ensuring compatibility with most modern motherboards. The mounting hardware is well-designed, and the installation process is straightforward, making it accessible for both beginners and experienced builders. The cooler's design also takes into account clearance for other components, minimizing the risk of compatibility issues.
Performance-wise, the Deepcool AK400 offers a noticeable step up from the AG400. It's capable of handling CPUs with higher TDPs, making it suitable for more demanding processors or overclocking. During testing, the AK400 consistently delivers lower temperatures compared to the AG400, especially under heavy load. The improved fan design also contributes to quieter operation, even at higher speeds. The AK400's enhanced cooling performance makes it a great choice for users who want to push their CPUs a bit harder or who prioritize quieter operation.
Key Differences: AG400 vs AK400
Okay, so we've introduced both coolers. Now let's pinpoint the key differences between the Deepcool AG400 and the AK400. While they might look similar at first glance, there are some important distinctions that could sway your decision.

Noise Levels
Noise levels are a significant consideration for many PC builders, especially those who value a quiet computing experience. A noisy CPU cooler can be distracting and annoying, especially during long gaming sessions or when working in a quiet environment. Let's compare the noise levels of the Deepcool AG400 and AK400.
According to the specifications, the AK400 has a slightly lower noise level compared to the AG400 (≤29 dBA vs ≤31.6 dBA). In practice, this difference is noticeable, especially under heavy load. The AK400's fan is designed to operate more quietly, even at higher speeds. This is due to the fan's optimized blade design and high-quality bearings.
The AG400 is by no means a loud cooler, but it can become audible under heavy load. If you're particularly sensitive to noise, the AK400 might be the better choice.
Both coolers feature PWM (Pulse Width Modulation) control, which allows the fan speed to be automatically adjusted based on the CPU temperature. This helps to keep the noise levels down when the CPU is not under heavy load. However, the AK400's superior fan design ensures that it remains quieter even when the fan is spinning at higher speeds.
Price and Value
Price and value are always important factors to consider when making a purchasing decision. The Deepcool AG400 and AK400 are both positioned as affordable CPU coolers, but there is a price difference between the two. The AG400 is typically the more budget-friendly option, while the AK400 commands a slightly higher price tag.
Considering the performance difference, the AK400 offers better value for those who need the extra cooling power or prioritize quieter operation. It's worth the extra investment if you have a higher TDP CPU or plan on overclocking. However, if you're on a tight budget and only need a modest upgrade from the stock cooler, the AG400 is a great option.
Ultimately, the best value depends on your specific needs and budget. Consider what you're willing to spend and what features are most important to you. Both coolers offer excellent value for their respective price points.
