Buying Guide
When shopping for 140mm case fans in 2017, there are several key factors to consider. We’ve put together this guide to help you make the best choice for your cooling needs.
Airflow vs. Static Pressure
Airflow fans move large volumes of air in open spaces, while static pressure fans push air through obstacles like radiators. Choose based on where you’ll install the fan.
Tip: Check if your case has mesh filters or tight spaces. If so, static pressure fans will perform better!
Noise Levels
Fan noise is measured in decibels (dBA). Quieter operations typically range from 15-25 dBA. Louder fans can exceed 30 dBA but might offer better cooling.
RGB and Lighting
Many fans now come with RGB lighting. Consider if this feature matters to you, as non-RGB options are usually more affordable.
CFM and Speed
CFM (cubic feet per minute) indicates how much air a fan moves. Higher numbers mean better cooling but often more noise.
| Fan Speed | Typical CFM | Best For |
| 800-1200 RPM | 50-70 | Quiet builds |
| 1200-1500 RPM | 70-90 | Balanced performance |
| 1500+ RPM | 90+ | Maximum cooling |
Connector Types
Check if your fan uses 3-pin or 4-pin (PWM) connectors. PWM allows for better speed control through your motherboard.
Bearing Type
The bearing affects fan lifespan and noise.
Fluid dynamic bearings last longer and run quieter than sleeve bearings but cost more.
