How To Buy Best 140mm Case Fans in 2022 | A Buying Guide

Before buying the best case fan, there are a few points to keep in mind. Let’s discuss them in detail.

1. Fan Speed

Fans’ rotational speed is calculated in terms of rotations per minute (RPM). The faster the fan rotates, the greater amount of airflow it can pump out, thus lowering the temperature of your system. To control the fan’s speed, search for a model with the PWM (pulse-width modulation). If you’re looking to go mechanical, you can change its settings as per the need.

2. Size

Best 140mm fans come in various sizes, such as 80mm, 120mm, 140mm, and even 200mm. Larger case fans typically have more airflow, and also produce less noise. That’s why 140mm fans are preferred these days since they are a good mix between efficiency, size, and cost.

3. Types Of Bearing

This aspect is ignored mostly by gamers but it still impacts the case fan. Sleeve bearings are most affordable, while ball bearings are long-lasting options. If you want quiet operations, then go for fluid bearings.

Choosing such fabs can help you get great value for your money. The majority of fan packs are simple to install in any computer case.

5. Noise Levels

This indicates what loudness can the fan achieve when it is operating at its highest RPM. The noise level of the majority of 140mm case fans is between 10 and 35 dB.

6. Airflow

The airflow in case fans is measured in CFM which is Cubic feet minute. This basically indicates the air amount a fan can push per minute.

7. Fan Lighting

The higher the RPM the greater the volume gets. It’s also better suited for a sleek design. A fan that runs at 1000rpm is an affordable price considering that the majority of normal case fans operate between 1400 and 1600rpm and would be suitable for a less-demanding work or leisure computer.
