Cybenetics power supply efficiency certification is a performance rating standard introduced by Cybenetics Lab, an independent testing laboratory headquartered in Greece. This certification evaluates power supplies based on energy efficiency and noise levels. But how does it differ from the traditional 80 Plus certification?

| Efficiency Certification Levels (ETA) |

Cybenetics classifies efficiency into six levels, ranked from highest to lowest: Diamond, Titanium, Platinum, Gold, Silver, and Bronze.

The Cybenetics LAMBDA certification evaluates the noise levels of power supplies under different loads and categorizes them into A++, A+, A, A-, Standard++, Standard+, and Standard.

Cybenetics LAMBDA Noise Certification Ratings

One of the key differences between Cybenetics and 80 Plus certification is that Cybenetics includes noise testing. It categorizes power supplies based on noise levels at different loads, allowing consumers to choose a power supply with both high efficiency and low noise.

In contrast, 80 Plus certification only evaluates power conversion efficiency and does not measure noise levels.

I was fortunate enough to be invited by darkFlash Taiwan to experience the debut of the back-insertion “sea-view” PC case. The first time I saw this case was at the 2024 Computex booth, where I learned that it features a back-insertion design, three large glass panels for maximum transparency, and an expansive layout—quite unique! When I received the invitation, I also had a set of ROG BTF components on hand, so I took up the challenge. While setting up the system, I hesitated a bit regarding cooling solutions. Almost all water cooling systems on the market still have tubing, and I felt that to achieve the perfect back-insertion aesthetic, something was still missing. Then I remembered that Bitspower, a leading local and international water cooling brand, had recently launched a back-insertion cooling head. After my excellent experience with their CR360 water cooler, I reached out to them, and they were kind enough to provide products for the build. So, let’s dive into this build experience!

The case packaging prominently displays the DY470 logo and design elements, with a very spacious box. The packaging is 

sturdy, justifying the size of the box, and you’ll find the accessory box embedded inside the packaging.

| Showcasing the Case from Different Angles |

The front cover features a sharp design with three intersecting glass panels that provide a sleek, premium feel. When the lights are off, the edges are defined, adding to its premium look. The top part of the case is made of transparent glass, which gives a more open visual feel when the system is powered on, offering excellent transparency.

The glass panels are secured with screws and feature a quick-release structure, making assembly and disassembly very intuitive.

The rear section reveals that the power supply is mounted vertically, and the fan mounts are designed specifically for 120mm fans.

The accessory box follows darkFlash's signature style, including the traditional glass cleaning cloth and standard screws. Additionally, the instruction manual is included, which is particularly useful since the three glass panels may require some extra attention during assembly. The steps for removing and installing the glass panels are more intricate, and the manual can be referenced to help guide you through the process.

I never imagined that a computer with this kind of gaming "lazy" modeling would actually exist in real life. In recent years, this intriguing build concept has finally come to life, and I was amazed by how visually seamless and comfortable the experience is. I deeply respect the developers and designers behind this innovation. It’s an honor to add such a memorable unboxing to my assembly journey.

PCIe, short for PCI Express, is a widely used bus standard on computer motherboards. It serves as a high-speed interface for connecting various computer hardware components, providing efficient and stable data transfer. PCIe is primarily used to connect devices like graphics cards, SSDs, network cards, and capture cards, among others.

PCIe uses a point-to-point serial connection, meaning each device connected to a PCIe slot has its own dedicated data transfer channel. This allows for significantly faster data transfer rates compared to older standards. PCIe slots come in different versions (e.g., PCIe 3.0, PCIe 4.0, PCIe 5.0), with each new generation offering almost double the data transfer speed of the previous one.

PCIe slots come in various lengths and lane configurations, including x1, x4, x8, and x16. The number after the "x" indicates the number of data lanes the slot has, which can be thought of as lanes on a highway. For example, an x16 slot offers 16 data lanes, allowing for higher throughput compared to smaller slots like x1, which only has one data lane.

PCIe is backward compatible, meaning a PCIe 4.0 device can be used in a PCIe 3.0 slot, but the device will be limited to the slower transfer speed of PCIe 3.0.

| PCIe Usage and Recommended Slot Types |

| Important Considerations When Using PCIe |

When choosing expansion devices, ensure that the bandwidth of the device matches the slot's bandwidth. Low-bandwidth slots will limit the performance of high-bandwidth devices.

Ensure that the physical size of the PCIe card is compatible with the motherboard slot. For example, an x1 card can be installed in a x16 slot, but an x16 card cannot be installed in a x1 slot.

Most motherboards have a slot priority system, meaning some slots are more suitable for high-priority devices like GPUs. To get the best performance, it is recommended to install critical components in slots closer to the CPU, as these slots often offer the best bandwidth and lowest latency.

PCIe slots are critical for expanding and enhancing the functionality of your computer. By understanding the different types of PCIe slots and their recommended uses, you can optimize your system's performance and expand its capabilities to meet your needs. Whether you're upgrading your graphics card, installing an SSD, or adding a network card, choosing the right PCIe slot is essential for maximizing the potential of your hardware.

For example, an x16 slot offers 16 data lanes, allowing for higher throughput compared to smaller slots like x1, which only has one data lane.



Backward Compatibility

PCIe is backward compatible, meaning a PCIe 4.0 device can be used in a PCIe 3.0 slot, but the device will be limited to the slower transfer speed of PCIe 3.0.



| PCIe Usage and Recommended Slot Types |



Graphics Card (GPU)





Recommended Slot: PCIe x16



Reason: Graphics cards require the highest bandwidth to handle demanding graphical computations. Therefore, they are typically installed in x16 slots, which provide the best data transfer rates to ensure optimal GPU performance.



Solid-State Drive (SSD)





Recommended Slot: PCIe x4



Reason: SSDs are usually installed in M.2 slots on the motherboard. However, if the motherboard lacks enough M.2 slots, an M.2 PCIe expansion card can be installed in a PCIe x4 slot to fully unleash the SSD's performance.



Network Card (NIC)





Recommended Slot: PCIe x1 or PCIe x4



Reason: While many network cards use USB for hot-swapping, a PCIe network card is typically chosen for more stable and reliable network connections. An x1 slot is sufficient for most network cards, but for higher-speed NICs, a PCIe x4 slot is recommended for improved stability.



Capture Card





Recommended Slot: PCIe x4 or x8



Reason: Capture cards are essential for streamers and content creators, as they handle high-bandwidth video data. To ensure smooth performance, capture cards usually require a PCIe x4 or x8 slot to provide enough bandwidth for high-quality video streaming.



| Important Considerations When Using PCIe |

Bandwidth Compatibility

When choosing expansion devices, ensure that the bandwidth of the device matches the slot's bandwidth. Low-bandwidth slots will limit the performance of high-bandwidth devices.

After discussing the principles of air coolers, let's dive into another popular cooling option: water coolers. As a more advanced solution for PC DIY enthusiasts, AIO water coolers are currently one of the most effective processor coolers available that most PC builders can afford. But what are the pros and cons of AIO water coolers?

AIO water coolers leverage the high thermal conductivity of liquids to transfer heat from the processor quickly to the radiator, resulting in superior cooling performance. This makes them one of the most efficient solutions for keeping your processor cool, especially under heavy loads.

Unlike air coolers, which require bulky heatsinks and fans to be installed directly onto the processor, AIO water coolers use a closed-loop system with tubes that transfer heat to an external radiator. This means the cooling head (the part that contacts the CPU) can be smaller and more compact, allowing for a cleaner, less cluttered internal setup. This design also helps avoid blocking access to components like RAM or the motherboard, giving you more flexibility in choosing and installing other components.

One of the standout advantages of an AIO cooler is that the radiator fan pushes hot air outside the case, rather than circulating it within the case as in air coolers. This helps to expel heat not only from the processor but also from other components inside the case, improving overall airflow and cooling for the entire system.

AIO water coolers are generally more expensive than traditional air coolers. For users who are particularly cost-conscious or focused on price-to-performance ratios, an air cooler may be a more budget-friendly option. The extra cost of an AIO cooler can be a downside for those looking for a more economical solution.

Although AIO water coolers have become much more reliable in recent years, there is still a small risk of leakage. While the technology and manufacturing processes are quite mature, leaks can still happen. If a leak occurs, not only will it affect the cooling performance of the processor, but the leaked liquid could also damage other sensitive PC components. To alleviate these concerns, many manufacturers offer extended warranties that cover leakage, ranging from three to six years, to attract customers.

Installing an AIO cooler is typically more complex than installing an air cooler. With air coolers, you simply attach the heatsink to the processor, clip on the fan, and connect the necessary cables. In contrast, an AIO water cooler requires you to install the water block (cold plate), radiator, and fans, along with several tubes and cables. This makes the installation process more involved and can be challenging for beginners or those who are new to PC building.

AIO water coolers offer exceptional cooling performance and a cleaner, more efficient setup compared to traditional air coolers. However, their higher price, potential risk of leaks, and more complicated installation process may make them less appealing to some users. For those who prioritize cooling efficiency and are willing to invest in a more advanced solution, AIO coolers can be an excellent choice. However, if you're on a budget or new to building PCs, you might want to consider an air cooler as a more cost-effective and simpler alternative.

Now that you understand the key advantages and disadvantages of AIO water coolers, you're in a better position to make an informed decision for your next PC build!

To alleviate these concerns, many manufacturers offer extended warranties that cover leakage, ranging from three to six years, to attract customers.



More Complex Installation

Installing an AIO cooler is typically more complex than installing an air cooler. With air coolers, you simply attach the heatsink to the processor, clip on the fan, and connect the necessary cables. In contrast, an AIO water cooler requires you to install the water block (cold plate), radiator, and fans, along with several tubes and cables. This makes the installation process more involved and can be challenging for beginners or those who are new to PC building.







AIO water coolers offer exceptional cooling performance and a cleaner, more efficient setup compared to traditional air coolers. However, their higher price, potential risk of leaks, and more complicated installation process may make them less appealing to some users. For those who prioritize cooling efficiency and are willing to invest in a more advanced solution, AIO coolers can be an excellent choice. However, if you're on a budget or new to building PCs, you might want to consider an air cooler as a more cost-effective and simpler alternative.



Now that you understand the key advantages and disadvantages of AIO water coolers, you're in a better position to make an informed decision for your next PC build!

While All-in-One (AIO) water coolers offer superior cooling performance, they also come with their own set of drawbacks and important considerations.

Since the advent of computer processors, air coolers, often referred to as tower fans by DIY enthusiasts, have played a vital role in cooling processors and improving performance. It wasn't until the introduction of all-in-one liquid coolers that air coolers began to see some changes. So, what should you keep in mind when selecting a tower fan? To make an informed decision, it’s essential to first understand the structure and cooling principles of a tower fan.

A tower fan typically consists of four main components: heat fins, heat pipes, base, and fan.

These are usually made of aluminum or copper and are designed to dissipate heat efficiently. They provide a large surface area for the fan to help cool the hot air generated by the processor.

Most heat pipes are made of copper, which is hollow and contains a small amount of heat-conducting liquid. As the temperature rises, the liquid in the base of the pipe evaporates, transferring the heat to the top of the heat pipe. The heat fins and fan then assist in cooling down the system. Once the temperature decreases, the vapor condenses back into liquid form and returns to the bottom of the heat pipe.

The base of the tower fan is typically coated with thermal paste, ensuring the fan's base is tightly connected to the processor for optimal heat transfer.

The fan is mounted on the heat fins via clips or screws, and it uses airflow to carry heat away from the heat fins and heat pipes. The speed and airflow of the fan are key factors in the overall cooling performance.

The cooling process in a tower fan starts at the base, where heat is transferred to the liquid inside the heat pipes. As the liquid heats up, it evaporates and moves to the top of the heat pipe, where the heat is dispersed by the heat fins and fan. The liquid then condenses back into a liquid state when cooled, continuing the cycle.

| Important Factors to Consider When Choosing a Tower Fan | 

Entry-level tower fans typically have 4 heat pipes, while flagship models come with 6 or 7 heat pipes. The more heat pipes a tower fan has, the better its heat dissipation capabilities. More heat pipes mean more effective heat transfer and better cooling performance.

The fan in a tower cooler is responsible for dissipating the heat from the heat fins. A fan with higher airflow will carry away the heat more quickly, which results in better cooling performance. The more airflow the fan generates, the faster the heat is removed from the system.

The more fans a tower cooler has, the better the cooling performance. Entry-level tower fans typically use a single fan, while high-end models use two or more fans to enhance cooling efficiency.

Important Note: For dual-fan tower coolers, be sure to check the height of your RAM. There can be compatibility issues if the tower fans interfere with the RAM modules, preventing proper installation.

Choosing the right tower fan for your PC build requires understanding the cooling technology behind it. Tower fans have evolved to become an effective solution for cooling processors, offering a straightforward yet efficient cooling mechanism. By considering factors like the number of heat pipes, fan performance, and fan quantity, you can make a more informed decision to ensure optimal cooling for your system.

Now that you understand the key components and how they work, you're ready to choose the perfect tower fan for your PC!

When it comes to PC building, one of the most tedious tasks is often managing the cables that connect your fans. Thankfully, recent innovations in fan technology have made things much easier, especially with the advent of snap-on fans. These fans, similar to a puzzle, allow you to connect them without the need for any cables — just touch points that complete the connection and power up the fan. Snap-on fans come in two main designs: magnetic and clip-on.

As the name suggests, magnetic snap-on fans rely on magnets to connect the fans together. Typically, these fans have magnets placed along the touch points on both sides and the bottom. This ensures a strong and stable connection between the fans, allowing them to easily connect and function properly without the need for wires.

To connect magnetic fans, all you need to do is bring the magnetic connection points close together. The fans will automatically attract each other and power on once they make contact. It’s a simple, hassle-free process that eliminates the need for traditional cables.

Clip-on snap-on fans use a different method for connection. These fans rely on clips or slots that secure the fans into place. Once the fans are clipped together, the touch points make contact, powering on the fan and allowing it to operate. This method requires a bit more effort in terms of installation, but it provides a secure, stable connection.

The Best Option for Lazy PC Builders: Snap-on Fans

Quando se trata de montar um PC, uma das tarefas mais fastidiosas é, normalmente, organizar os cabos que ligam as ventoinhas.

A melhor opção para quem gosta de montar PCs sem preguiça: ventoinhas de encaixe.

Nowadays, most PC cases come with pre-installed fans for DIY builders. However, many cases only include up to four fans by default. For those who seek peak cooling performance, it's common to purchase additional fans to improve airflow. But did you know? The key to effective cooling isn't just about the number of fans; the direction of airflow is just as crucial. So, how should you position your fans to achieve the best cooling performance?

Whether you have a standard case with a front panel or a popular “seaview” (open-frame) case, the principle of airflow remains the same. There’s a simple rule to follow: "Front and bottom intake, rear and top exhaust." This means that the front (or side panel, for seaview cases) and bottom of the case should have intake fans, while the top and rear panels should have exhaust fans.

Why is this so effective? Because heat naturally rises within the case. The exhaust fans at the top and rear are placed closest to the hot air, helping to quickly expel it from the system. Meanwhile, the intake fans at the front and bottom draw in cool air, creating a constant flow of fresh air into the case. This setup ensures that hot air is efficiently removed, and cool air is consistently drawn in, leading to optimal cooling performance.

With the growing popularity of seaview cases (cases with a more open design, often without a front panel for fan installation), manufacturers have had to rethink fan positioning. Since these cases lack space for fans at the front panel, fans are often mounted on the side panel instead. However, if you follow the traditional fan placement method for optimal cooling, the fan's back will face the inside of the case. This results in unsightly exposed cables and can make cable management a hassle.

To address both aesthetic and cable management concerns, many fan manufacturers have introduced 

 versions of their models. These reverse-blade fans allow the fan’s back to face outward, offering a cleaner look while maintaining optimal airflow.

The best airflow configuration for your PC case should be based on the design of the case, the internal component layout, and your specific cooling needs. Generally speaking, a "front-bottom intake and rear-top exhaust" design provides stable and efficient airflow circulation.

To further enhance your system's cooling efficiency:

By properly configuring the fans and optimizing airflow, you can keep your PC’s components cool, quiet, and running efficiently.

Whether you’re building a PC for gaming, content creation, or productivity, understanding the right fan installation direction is key to achieving optimal cooling performance. By following the principle of "front and bottom intake, rear and top exhaust," you’ll create an effective airflow system that ensures your PC stays cool, even during heavy loads. Keep in mind that your case’s design, component placement, and cooling needs should guide your fan setup, and don’t forget to manage cables for both aesthetics and efficiency!
