When building a PC, choosing the right case fans is essential for maintaining proper airflow and cooling. The size of the fans you choose will largely depend on the size of your PC case, as well as your specific cooling needs. Here’s a rundown of the most common PC case fan sizes and their characteristics:
- 120mm: The most common size for PC case fans, 120mm fans are versatile and widely available. They are a good choice for mid-tower and smaller cases, as well as for use as intake or exhaust fans. Many high-quality 120mm fans are available on the market, including models with high airflow, low noise, and customizable RGB lighting.
- 140mm: Slightly larger than 120mm fans, 140mm fans offer higher airflow and can move more air at lower RPMs, which can result in quieter operation. They are a good choice for larger cases or for use as exhaust fans. While they may be less common than 120mm fans, there are still many high-quality 140mm fans available.
- 200mm: These large fans are typically found in full-tower cases, where they can provide a significant amount of airflow with low noise. They are typically used as intake fans, as they can draw in large amounts of air and help cool your components. Some 200mm fans also come with customizable RGB lighting to add some extra flair to your build.
- 80mm: 80mm fans are smaller and less common than 120mm and 140mm fans, but they can still be useful in certain situations. They are often used in small form factor (SFF) cases or in situations where space is limited. They are generally less efficient than larger fans and may produce more noise at higher RPMs.
- 92mm: Slightly larger than 80mm fans, 92mm fans are still relatively compact and are commonly used in SFF cases or in situations where space is limited. They can provide good airflow in a small package, but may produce more noise than larger fans.
- 60mm: The smallest of the common PC case fan sizes, 60mm fans are rarely used in modern PC builds due to their limited airflow and higher noise levels. They may be used in very small cases or in situations where space is extremely limited.
When choosing PC case fans, it’s important to consider not only the size of the fan, but also its other specifications, such as its airflow rating, noise level, and bearing type. Some fans are designed to be more efficient or quieter than others, so it’s important to choose the right fan for your specific needs.
It’s also worth noting that some cases may support different fan sizes or configurations, depending on their layout and design. Some cases may allow for multiple fans of different sizes, while others may only support a specific fan size or layout. Before purchasing fans for your build, it’s important to check your case specifications to ensure compatibility.
In addition to fan size, it’s important to consider the placement of your fans for optimal airflow and cooling. In general, it’s a good idea to have intake fans at the front of your case and exhaust fans at the back or top. This allows cool air to be drawn in through the front of the case and hot air to be expelled through the back or top, creating a steady flow of air that helps keep your components cool.
Overall, choosing the right size of PC case fan is an important part of building a well-cooled and efficient PC. By considering your case size, cooling needs, and fan specifications, you can select the right fans to keep your components cool and running smoothly.
