How are Computer Fans Measured

Computer cooling fans are measured in terms of their airflow, which is the volume of air that they can move in a certain amount of time. The most common unit of measurement for airflow is CFM, or cubic feet per minute. The higher the CFM rating of a fan, the more air it can move.

Are you wondering how computer fans are measured? Well, the answer is actually quite simple. Computer fans are measured in terms of airflow and static pressure.

Airflow is the volume of air that the fan can move in a given period of time, and is typically measured in cubic feet per minute (CFM). Static pressure is the amount of resistance that the fan faces when trying to push air through an obstruction, such as a filter or heatsink. It’s usually measure in inches of water (inH2O).

Choosing & Installing PC Cooling Fans As Fast As Possible

What is Cooling Fan in Computer

As its name suggests, a cooling fan in computer is used to help cool down the various components inside the computer. Most computers will have at least one fan, and some may even have multiple fans. The purpose of these fans is to keep the components from overheating and prevent damage to the computer.

The most common type of cooling fan is an air-cooled fan, which works by blowing air over the components. There are also liquid-cooled fans, which use water or other fluids to cool down the components. Some high-end gaming computers may even use both types of fans for extra cooling power.

No matter what type of cooling fan you have, it’s important to make sure that it’s working properly. If you notice that your computer is starting to overheat, be sure to check the fans first to see if they need cleaning or replacement.

Types of Computer Fans

Computer fans come in a variety of shapes and sizes, each designed for a specific purpose. The most common type of fan is the CPU fan, which helps to cool down the processor. Other popular types of fans include case fans, which help to cool down the inside of the computer, and GPU fans, which help to cool down the graphics card.

CPU fans are typically located on the back of the computer case, near the top. They come in a variety of sizes, but most are 80mm or 120mm. CPU fans typically spin at around 1,500-2,000 RPM and can move up to 70 CFM (cubic feet per minute) of air.

Case fans are usually located on the front or back of the computer case. They come in a variety of sizes, but most are 120mm or 140mm. Case fans typically spin at around 1,200-1,500 RPM and can move up to 60 CFM (cubic feet per minute) of air.

GPU fans are usually located on the side of the graphics card. They come in a variety of sizes, but most are 80mm or 90mm.

Are All Pc Fans the Same Size

When it comes to PC fans, there are a few different sizes that you will see. The most common size is 80mm, but you will also find some that are 120mm or even larger. So, when it comes to choosing a fan for your PC, what size should you choose?

Well, it really depends on a few factors. First, you need to think about the size of your case. If you have a small case, then you probably don’t want to go with a huge fan because it just won’t fit.

Second, you need to think about the airflow in your case. If your case has good airflow, then a smaller fan might be all you need. But if your case doesn’t have good airflow, then you might want to consider a bigger fan so that it can move more air and keep your components cooler.

Finally, it also depends on how much money you want to spend. Smaller fans are usually cheaper than bigger fans, so if cost is a factor, then that might be something to consider as well. So, there’s no one answer when it comes to what size PC fan you should buy.

It really depends on your specific situation and needs. Just make sure to take all of these factors into consideration before making your final decision!

Computer Fan Usb

A computer fan USB is a great way to keep your computer cool and avoid overheating. It is easy to use and can be plugged into any USB port. The fan will help circulate air around the inside of your computer, which will prevent it from overheating.

80Mm Fan

An 80mm fan is a small fan that is commonly used in computer cases, and other electronic devices. Its size allows it to be used in many different applications, and its popularity means that there are many different types of 80mm fans available on the market. When choosing an 80mm fan, it is important to consider the noise level, airflow, and static pressure.

Computer Fan Sizes in Inches

When it comes to computer fan sizes, there are two things that you need to take into account: the width of the fan, and the height of the fan. The width is always measured in inches, while the height is usually measured in millimeters. The most common size for a PC fan is 80mm, which is about 3.15 inches wide.

However, you can also find fans that are 60mm (about 2.36 inches), 70mm (about 2.76 inches), 90mm (about 3.54 inches), 100mm (about 3.94 inches), and 120mm (about 4.72 inches) wide as well. As for the height of the fan, it can range from 25mm (about 0.98 inch) all the way up to 38mm (about 1.5 inches). In general, taller fans tend to move more air than shorter ones, but they also produce more noise since they have to spin faster in order to do so.

How are Pc Fan Sizes Measured?

When it comes to measuring the size of a PC fan, there are two main methods that are typically used. The first method is by using the measurements of the fan blades themselves. This is usually done in millimeters and will give you the exact size of the fan.

The second method is by measuring the fan’s housing. This is typically done in inches and will give you an overall measurement of the fan. It’s important to note that when shopping for fans, blade size isn’t always indicative of how powerful the fan is.

For example, a smaller Blade may move more air than a larger one due to its design or RPM (revolutions per minute). Nevertheless, knowing how big or small your case’s ventilation holes are will help you determine which sized fans will work best for your build. When it comes to choosing PC fans, there are a few things you need to take into account such as: static pressure, airflow, noise levels and compatibility.

Once you have all of that information figured out, then you can start looking at different sizes and models to see which one fits your needs the best!

How Do You Measure a 120Mm Fan?

There are a few things you need to take into account when measuring a 120mm fan. The first is the size of the fan itself. The next is the thickness of the fan, which will determine how much air it can move.

Finally, you need to consider the speed at which the fan spins. The size of a 120mm fan is typically 120x120x25mm. However, some fans may be slightly larger or smaller than this.

To get an accurate measurement, it’s best to use a ruler or tape measure. The thickness of a 120mm fan is usually given in millimeters (mm). This refers to the distance between the blades of the fan and determines how much air it can move.

A thicker fan will be able to move more air than a thinner one. The speed at which a 120mm fan spins is measured in revolutions per minute (RPM). The higher the RPM, the faster thefan will spin andthe more air it will move.

What Does 120Mm Fan Mean?

A 120mm fan is a computer cooling device that helps to move air around the inside of a computer case. It is typically used in conjunction with other cooling devices, such as heat sinks and radiators, to keep components cool and prevent overheating. A 120mm fan typically has a higher airflow than smaller fans, making it more effective at cooling larger areas.

How Do I Know What Size Fan I Need?

There are a few factors you’ll need to consider when purchasing a new fan or determining what size fan you need. The first is the size of the room – fans come in a range of sizes, so you’ll want to make sure you get one that’s appropriate for the space. The next factor is ceiling height – if your ceilings are low, you might want to opt for a flush-mount fan rather than a hanging one.

And finally, consider the airflow needs of the room – if it’s particularly hot or humid, you might need a stronger fan with more blades.


In order to ensure that a computer fan is effective, it is important to know how they are measured. The size of a computer fan is typically determined by the width of the blades. The larger the blades, the more air they will be able to move.

Additionally, the speed of the fan blades is also important. The faster the blades spin, the more air will be moved. For most computers, fans come in sizes ranging from 80mm to 140mm.
