Buying Guide: How To Choose The Best 140mm Case Fans?

Besides the review, certain factors will help you buy the best case fans for your CPU. So, here are some tips that will help you choose the best cooling fan.

1. Noise Level(s)

This is one of the best things to check before buying the right cooling system. The higher the RPM, the less noise will occur. However, this is not always true. In some cases, a high-speed fan may generate more noise than a low-speed one.

So, you should check whether there are any advanced features that help you minimize noise production. It is also recommended to check for options that produce less noise as compared to the existing ones.

2. Size

The size of a case fan is one of the most important things to consider while buying a cooling system. The dimensions, per se, do not make the fan inefficient. The efficiency comes from the ability of the fan blade to get rid of all the heat.

So, it is best to go for good-sized case fans that do not reduce air pressure when they rotate. This will help you get a better pull of air. The size of the fan is also greatly dependent on the amount of airflow that you want to get inside your system. Therefore, it is best to go for a smaller fan if you want more airflow.

3. Quality

Once again, it is not possible to remove noise from the case fans. You cannot buy one that produces less noise and expect it to be efficient. So, if you want better efficiency with minimum noise, then choose an advanced quality product with enhanced features.

For example, a high-end product with noise reduction features will be a better choice. Also, you should always check the fan blade quality. The higher the quality of the blades, the less noise will occur. However, there is always a compromise because you cannot expect to get high RPM from low-quality fan blades.

4. Power Consumption

The power consumption of the case fans is also important for efficient operations. You can compare the power consumption and speed of different fans to get one that consumes less power and offers more speed. The power consumption can be reduced if you go for a low-speed fan.

However, it is not always true that low-speed fans offer less power consumption. You should always check the specifications of the fan to get a better idea about its power consumption. You should also look at the size of your system case and see whether it can handle this amount of power or not.

5. Warranty

If you are spending hundreds on the cooling system, then a warranty becomes an important factor to consider. Moreover, it will also help you to get better services from the manufacturer. It is always wise to select a case fan with a longer warranty.

You should also make sure that the company will provide you with all the contact information as well as the original invoice copy to handle any questions/complaints. You can easily get these at the manufacturer’s website.

6. Ventilation

Every system requires ventilation when it is installed in the room. So, you should check whether your case has any extra vents on the top side. These vents will allow air to flow in and out of the system without compromising its efficiency.

There are many cases that do not offer extra vents because they require additional hardware to cover all the components inside the case. So, make sure you go for a case that allows enough flow of air.

7. Connector Type

Another feature that you should check while buying a case fan is the connector type. The majority of modern-day CPUs and GPUs are compatible with most of the case fans. However, some cases may not be compatible with your system.

So, you should check whether any other connector type can be used to connect it with your system. If the case fan is compatible with your CPU, then it is a better choice. However, there are certain cases where you cannot use any of the case fans with certain connectors.

8. Budget

Finally, this is one of the most important things that you should consider while buying a cooling system. You should always have a budget in your mind while buying the case fan to avoid unexpected situations.

Also, you should choose a good quality product within your budget so that you can get higher performance levels without compromising on its quality. So, while picking the case fan, you must keep all these factors in mind so that you can get a perfect purchase.

9. RPM

RPM or rotations per minute is the best indicator to measure the speed of a cooling system. The higher the RPM, the better will be its ability to pull air out from your system.

However, there is always a tradeoff between noise production and the efficiency of the cooling fan. So, studying the RPM is important before getting one for yourself. For example, if you have a high-speed fan with good RPM, it can produce more noise at first and then offer excellent performance after some time.

10. Airflow

Airflow is another important factor that can be measured by the blades used in the case fan. The higher the airflow, the bigger is its ability to pull air out of your system. However, it is highly recommended to go for a case fan with a high blade count because it will enhance efficiency and also produce less noise.

So, you can always check the specification of a fan to find out how many blades are present in it. Also, by checking its airflow rating, you will be able to measure the efficiency of the case fan.

Conclusion

Keeping it short, these are the ten best 140mm case fans that you must consider while buying your case fan. Now that you know the top ten products, you can draw a better conclusion and find out the case fan that is most suitable for your CPU/GPU. Besides, you should also follow the buying guide if you want to purchase the best case fan.
