These are the two options available to those who want to build their own PC. Each fan can offer different advantages and features. However, computer users must be aware that high temperatures and overheating of processors or computers can lead to serious health problems.
We have therefore set ourselves the task to compare 140mm and 120mm fans. We will discuss each one below to help you choose the best option based on your computer’s activities.
120mm PC Case Fans
A 120mm fan’s airflow is one of its main features. Each fan is different and each manufacturer can offer a different airflow. However, the average fan airflow with the 140mm fan is different.
You can expect to get up to 90 cm/min of airflow. This means that the fan can deliver low levels of airflow. This fan can be used for computers that don’t perform heavy-duty or intensive tasks. These activities don’t require high-require games or design software.
These fans can produce a lot of airflows, depending on their speed (or the number of revolutions per minute). A 120mm fan can achieve an average speed of 1200 revolutions per hour. This speed is acceptable for computers that do light tasks, as we can see.
There are 120mm fans with low noise levels that can be found due to their small size. These fans have DB levels that are specific to each manufacturer. This aspect can be optimized by fans that use the software.
The software that controls the fan allows you to adjust the operation to suit your needs and the temperature of your computer. Sometimes the fan doesn’t make any noise when it is not necessary to turn the operation on. A 120mm fan of good quality can produce approximately 26 DB.
We also discover a variety of options when we look at the price of each fan. This is due to the manufacturer’s inclusions. Fans 120mm may not be affordable. In some cases, it can cost more than $50 to get the best quality.
140mm PC Case Fans
Due to intense activities, some computers can generate excessive heat. Best 140mm case fans are better suited to computers that engage in intense or intermediate activities. This fan provides high airflow.
This can occur with high-resource games, which require a very high level of performance. The same scenario can be created with design software, or with a computer that is used for many hours per day. 140mm fans are better suited for high temperatures.
This is also related to fan speed, which averages 1400 revolutions per hour. Some fans can provide speeds of up to 1500 to 2000 revolutions per hour, while others may offer even higher speeds. A higher speed means that there is more airflow available to protect the processor as well as all other parts of the computer.
Each 140 mm fan’s design and features will also influence the noise level. These fans can produce noise levels that exceed 30 DB. According to some users, it is possible to locate other fans that produce too much noise.
Many manufacturers include software that allows them to control each fan’s operation. This allows the fan’s operation to be controlled according to the needs of the processor. This reduces the fan’s noise.
The budget required to find a 140mm fan at a reasonable price is $20. There are many other fans that have a higher quality than the 140mm fan, and these can be found for as high as $50 or $60. This is because a 140mm fan has more power and more technology depending on the manufacturer.
120mm VS 140mm Fan Comparison
Comparing these fans gives us a better understanding of which fan to choose. Each fan is designed to provide functionality and benefits, depending on how the user uses it.
1. Airflow
The 140mm fan provides more airflow than the 120mm fan, as we’ve already mentioned. The 140mm fan is more suitable for heavy users or computers with high-end computing requirements.
2. Spinning Speed
We find 140mm fans to be more efficient than 120mm fans. This can be variable as a 120mm fan can reach 1200 RPM at maximum speed, while a 140mm fan can run at 1000 RPM. A 140mm fan will usually offer a faster speed if we select a suitable model.
3. Noise Level (dB)
140mm fans are noisier than 120mm fans. This option is usually quieter or more silent. A 120mm fan may be able to produce 20 decibels of operation.
4. Price
The 120mm fan is more affordable than a 140mm fan. On most occasions, a 120mm fan will cost between $10 and $30. A 140mm fan can be found between $15 and $20 to $35.
Final Verdict – The Winner
The 140mm fan is the best option for users looking for high functionality. The fan’s high temperature can withstand computers with heavy workloads.
The 120 mm fan is the best for users who need silence but use a computer to do light tasks. The fan can be used for light tasks such as office work. The 120mm fan is a great choice because of its quiet operation and affordable price.
