Currently, the most common case fans on the market are 120 mm and 140 mm. However, fans pre-installed in cases are still predominantly 120 mm. What are the differences between these two sizes, and should you consider upgrading to a 140 mm fan?

| Differences Between 120 mm and 140 mm Fans |

The primary differences between 120 mm and 140 mm fans are airflow, cooling performance, noise levels, and case compatibility.

When operating at the same speed, a 140 mm fan will generate higher airflow, resulting in better cooling performance compared to a 120 mm fan.

At the same noise level, a 140 mm fan operates at a lower speed while providing stronger airflow. However, at the same fan speed, a 120 mm fan will produce less noise.

Since 140 mm fans require larger spaces and screw holes that specifically fit the 140 mm size, not all cases support 140 mm fans. It’s important to check compatibility before purchasing.

| Who Should Upgrade to 140 mm Case Fans? |

140 mm fans offer higher airflow at full speed, lowering internal temperatures more effectively than 120 mm fans.

140 mm fans tend to be noisier than 120 mm fans. They are ideal for users who typically wear headphones while gaming or using their PC for extended periods.

| Why Aren’t 140 mm Case Fans the Mainstream Choice? |

While some cases come pre-installed with 140 mm fans, 120 mm fans are still the most common choice. This is due to several reasons:

140 mm fans tend to be slightly more expensive than their 120 mm counterparts. For example, the Owl NF-P12 and NF-P14 fans are priced at $20 and $23, respectively. The price difference of $3 per fan can add up to $9 for 3 to 4 fans. However, real-world testing shows that a 140 mm fan only reduces temperatures by about 1 degree compared to a 120 mm fan, which may not justify the higher cost.

Most consumers do not run their PCs at full speed for extended periods. The airflow and cooling performance of 120 mm fans are sufficient for everyday use, so upgrading to 140 mm fans is often unnecessary.

PWM stands for "Pulse Width Modulation," and it controls the fan speed by adjusting the frequency of current pulses. This allows for more accurate fan speed control, which helps optimize both performance and noise reduction.

How to Identify a PWM Fan vs Non-PWM Fan?

A PWM fan typically uses a small 4-pin connector. When this 4-pin connector is plugged into the motherboard, it receives PWM signals from the motherboard, adjusting the current switching frequency through pulses, which in turn controls the fan speed. Therefore, any fan with a 4-pin connector is likely a PWM fan, while fans with fewer pins are generally not PWM-controlled.

PWM fans adjust their speed based on system temperature, allowing for precise regulation of fan speed. Some software even enables manual adjustment of fan speed.

Because the system adjusts the fan speed based on the computer’s load, the fan is not constantly running at high speeds. This reduces wear and tear on the fan and helps extend its lifespan.

At lower loads, the fan can run at slower speeds, reducing noise. At higher loads, the fan speed increases to ensure effective cooling and gaming performance.

The DM12 Pro is a 4-pin PWM fan that doesn’t require a control box to daisy-chain multiple fans. The fan frame features a sleek design with LED lights that create a more even glow across the fan. The DM12 Pro also offers both positive and negative blade options, making it an essential fan for a "sea-view" style case.

The Gauss G24 ARGB Fan is darkFlash's first fan to use magnetic connections, eliminating the need for messy cables between fans. This enhances the efficiency of building a DIY PC. Despite using magnetic connections, the fan doesn’t compromise on performance and boasts a maximum speed of 2000 RPM, making it ideal for use as a radiator fan in water cooling setups.

PWM Fans: The Best Choice for Efficient Cooling and Silence

PWM fans are an excellent choice for combining high cooling efficiency with low noise levels, especially for gaming PCs and systems under high-load conditions.

Whether you're choosing a fan for an air cooler or a water cooler, the fan's role in dissipating heat from the case is essential. To help you make an informed decision, here are the five key factors to consider when picking a fan:

Common fan sizes on the market are 120mm (12cm) and 140mm (14cm). Larger fans, such as the 140mm ones, can provide greater airflow and thus better cooling performance, especially at the same RPM (revolutions per minute). However, not all cases can accommodate 140mm fans, so it's important to check the size compatibility of your case before purchasing. If you can fit the larger fan, it’s generally worth opting for it due to its superior airflow.

A fan with a higher RPM can deliver more airflow and pressure, which means it can move heat more efficiently. However, the trade-off is that higher speeds often result in increased noise and potential fan vibrations. To address this, many fans now come with PWM (Pulse Width Modulation) speed control, allowing the fan to adjust its speed based on the system’s temperature. Under heavy load, the fan will increase its speed to cool down the components quickly, and when the system is under light load, the speed will decrease to maintain basic cooling while minimizing noise.

Airflow (CFM - Cubic Feet per Minute): Airflow refers to the volume of air the fan can move per minute. A higher airflow means the fan can remove heat more effectively from the case.

Static Pressure (mmH2O): This measures the fan's ability to overcome resistance to airflow, such as when there are radiators or cooling fins in the way. A fan with higher static pressure is better suited for use with radiators or heat sinks, where airflow is obstructed and needs extra force to pass through the components.

There are various types of bearings used in computer fans, such as Fluid Dynamic Bearings (FDB), Hydraulic Bearings, and Sleeve Bearings. The type of bearing affects the fan’s lifespan, noise level, and stability. Fluid Dynamic Bearings (FDB) are often considered the best because they provide a balance of low noise and high performance. A well-designed fan with quality bearings can provide high airflow and pressure while maintaining quieter operation over time.

The position where you install your fan is just as important as the fan itself. Even with a high-performance fan, poor airflow management in your case could prevent the fan from performing at its best. Ensuring that your case has a good airflow path is essential for optimal cooling. The fan should ideally create a smooth intake and exhaust airflow system, directing cool air into the case and pushing hot air out. For tips on the best installation directions for case fans, consider exploring guides on 

The Best Fan Installation Direction for Your PC Case.

The performance of your computer fan is influenced by several factors, including size, speed, airflow, pressure, bearing type, installation position, and environmental conditions.

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.

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!

RGB and ARGB: An Essential Guide for Gamers

RGB lighting has become a must-have feature for gamers, commonly found in peripherals like fans, keyboards, and other computer components. But you may have heard terms like RGB and ARGB used interchangeably—are they the same thing? What’s the difference? Let’s dive in.

RGB combines three primary colors—red, green, and blue—to create a wide range of colors. Traditional RGB lighting systems can only display one color at a time, meaning all LEDs light up in the same color.

The "A" in ARGB stands for "Addressable," meaning each LED can be individually controlled. This allows for dynamic and varied lighting effects, such as gradients, flowing patterns, and more. ARGB is more versatile and visually impressive than RGB but is typically more expensive.

RGB devices usually connect to a motherboard or controller via a 4-pin interface, which includes 12V, R, G, and B pins. It’s crucial to follow the motherboard’s manual when installing, as incorrect connections can damage the RGB fan.

ARGB devices connect using a 3-pin interface, which includes 5V, Data, and Ground. ARGB connectors are designed with a foolproof mechanism to prevent incorrect installation, reducing the risk of damage.

Cannot control individual LEDs; all LEDs show the same color or pattern.

Enables complex and customizable lighting effects, such as flowing rainbows or dynamic waves.

The current standard for gaming fans, keyboards, and other peripherals.

Ideal for gamers on a budget who still want a splash of lighting. RGB fans are straightforward and offer limited lighting options, making them perfect for those who prefer a plug-and-play solution without extra configuration.

Perfect for gamers with a larger budget and a passion for customization. ARGB fans allow users to create unique lighting effects through motherboard software or third-party tools. If you enjoy tweaking settings and want a standout aesthetic, ARGB fans are the way to go.

By understanding the key differences between RGB and ARGB, you can make a more informed decision when purchasing peripherals that fit your preferences and setup. Whether you prioritize simplicity or customization, there's a lighting solution that’s perfect for you!
