Buying Guide
Choosing the best 140mm case fan can be tricky. We’ve put together some key factors to consider before making your purchase.
Airflow vs. Static Pressure
Fans come in two main types. Airflow fans move air efficiently in open spaces. Static pressure fans push air through obstacles like radiators.
Tip: Choose airflow fans for case ventilation and static pressure fans for radiators or tight spaces.
Noise Levels
Nobody wants a loud computer. Fan noise is measured in decibels (dBA). Lower numbers mean quieter operation.
Fans with rubber corners or vibration dampening help reduce noise. Many quality fans operate below 25 dBA at full speed.
RGB and Lighting
RGB lighting adds style to your build. Some fans offer full RGB with software control, while others have simpler LED lighting.
Connection Types
| Connection Type | Power Source | Speed Control |
| 3-pin | Motherboard | Voltage control |
| 4-pin PWM | Motherboard | Pulse width modulation |
| Molex | PSU direct | None (full speed) |
We recommend PWM fans for the best balance of performance and noise control.
Bearing Type
The bearing affects fan lifespan and noise. Fluid dynamic bearings last longest and run quietest. Ball bearings offer durability in any mounting position.
Air Pressure and CFM Ratings
CFM (cubic feet per minute) measures airflow volume. Higher numbers mean more air movement.
For radiators, also check air pressure ratings (mm H₂O).
