Your 2025 Guide to Choosing the Best PC Case Fans

✅ What Is a Case Fan?

A case fan draws cool air into your PC case and expels hot air out, helping to regulate internal temperatures and keep critical components like the CPU and GPU cool.

???? Why Are Case Fans Important?

• Improve airflow and cooling

• Enhance system stability and performance

• Reduce noise levels

• Extend component lifespan

???? Common Fan Sizes & Types

• Sizes: 120mm and 140mm are most common

• Connectors:

  • 3‑pin (basic speed control)

  • 4‑pin PWM (dynamic speed control)

• Bearing types: Fluid Dynamic, Hydraulic, Ball Bearing

⚙️ Key Specs to Consider

• CFM (Airflow): Aim for 50+ CFM

• Static Pressure: Ideal for radiators – look for 2.0+ mmH₂O

• Noise Level (dB): Under 30dB is preferred

• RPM: Between 1000–1500 RPM balances cooling and noise

???? Ideal Fan Placement Inside the Case

• Intake Fans: Front and bottom
