There is a lot to consider when building a computer system.
Be careful when using case cooling fans.
This guide will give you all the information you need to make the best decision. We’ll look at the size, price, power, noise, and performance of each fan.

What do you need to know about 120mm fans?
120mm fans are the most popular. For regular computer use, a 120mm fan will cool the case.
It is much smaller than other fans. This mount is great for small cases and builds with smaller parts. It does not have cooling options.
120mm fan dimensions are 120mm x 120mm x 25mm on average. Some fans might be slightly larger than others, especially if they have RGB lighting.
What 140mm fans are you looking for?
More people are buying the best 140mm case fans, even though they’re larger. Professionals who use heavy software like architects and editors love the 140mm computer fan.
There is a lot being said about 140mm static pressure fans. They can take up space that is otherwise reserved for other fans.
140mm fan dimensions are on average 140mm x 140mmx25mm. There are some fans that are larger than the 140mm, particularly if they have RGB lighting.
What does it have to do with size?
Before you buy a fan for your project, consider the size of the case. Most modern cases can hold fans up to 140mm, 120mm, or 80mm.
Some cases can hold up to 200mm, while others will fit 40mm. The mounting holes can be used to measure the fan’s dimensions.
Consider whether the fan will need to be mounted vertically or horizontally.
While this won’t affect your bearing selection in the long term it can have an effect on the type and price of the bearings you select.
120mm fans vs. 140mm fans: Let’s compare
There is a significant difference between 140mm fans and 120mm fans. 140mm fans are more efficient in cooling, airflow, and performance than 120mm fans.
These are the main factors to consider when comparing 140mm fans with 120mm fans.
Cooling down the entire system is the main goal of any fan. To determine if a fan has the capacity to cool the system adequately, we need to look at the CFM or RPM.
CFM stands for cubic feet per minute. CFM is cubic feet per minute.
Cooling does not just depend on the length of the blade. Cooling is also affected by the design and material of the blade.
The round per minute is RPM. This is the speed at which the fan spins per hour. Fans with 120mm diameters will have a faster RPM than those with 140mm.
- 140mm fans win but 120mm fans provide excellent cooling.
– Static pressure
Another thing to consider is the static pressure rating of your fan. This indicates how much airflow fans produce that penetrates heatsinks and mesh enclosures.
It is hard to categorize this category because fans have different uses depending on the amount of cooling required. Fans can also be used to combat dust and other contaminants.
Static pressure ratings are nearly always in an ideal condition, with no dust or other particles.
In this category is hard to pick a winner. Many are concerned about static pressure ratings.
You can choose between two fans if you aren’t sure what to do. The fan will typically be 140mm in diameter.
- Winner: It’s tied but 140mm by one foot
Noise is a key consideration when building any type of PC. There are fans that are nearly silent
Fans today are generally quiet, especially if they’re ones you’re buying. 140mm fans can be quieter because they don’t have to move as often in order to maintain the same cooling rate.
Noise can also be affected by speed and environment. You won’t find a clear winner.
- 140mm fans are more efficient than traditional fans, as they require less spinning to cool the fan.
– Working Your Fan Into Your Build
Consider the dimensions of the computer case to determine if it can accommodate your fan. Adjust your fan options as needed.
140mm fans require more space. A 120mm fan allows you more flexibility and options.
You should also consider the bearings that you’ll be using for your build. This can affect the fan’s size and weight.
- Rifle bearings offer the best value. These fans come with many 120mm fans as well as many 140mm fans. These fans cannot be pre-built.
- Although they are more expensive, Ball bearings are still very popular.
- Most fans can use Maglev bearings. These bearings are the best for installation.
How you interact with them will depend on your case. Most fans offer all three options.
- Winner: 120mm Fans, because they offer more options for different cases
– The Fan’s Overall Value
Consider the contribution of your fan to your system. Fans that have 120mm fans are more costly than those with 120mm.
A fan that is less expensive than your current one is worth the extra money.
If your building is heating up a lot, you will need to reduce the number of 140mm fans. This will help you save money.
- Winner: 140mm. This is particularly important if you have many fans
What is Lighting?
Lighting is becoming increasingly popular. The fan is larger but offers more options and costs more than the 120mm fan.
The only thing you need to think about is whether or not you will need lighting for your fan. If so, you will need more fans.
A second thing to consider is DC vs. PWM
It is possible to choose between a 120mm fan or a 140mm fan.
The 3-pin headers that attach to your motherboard control a direct current fan (DC fan).
A PWM fan, or pulse-width modulation, however, has an additional pin that allows it signal to other parts of the machine more easily.
While there aren’t many differences between the two types, a PWM fan is quieter and more reliable over time. If you want to build a future-proofed home, a PWM fan may be the right choice.
How does overclocking affect fan size and quality?
Think about the pressure that your 140mm fan will have to withstand.
Overclocking may cause heat and affect your performance. A 140mm fan allows you to push your system further than usual without worrying about damaging any components.
Conclusion: Which size fan do you prefer?
There are many things to take into consideration when building a computer. One of these is fan size.
There are many options for the size of your fan. However, we think most people will be happier if they have a 140mm fan.
- 140mm fans have more power, are quieter and provide cooler cooling than other fans.
- 140mm fans can be more expensive, but they offer great value.
- You will need to buy fewer 140mm fans
120mm fans are still possible. You need to think beyond size and choose a fan that is suitable for your needs.
