Best 140mm Radiator Fans

Radiators play a pivotal role in liquid cooling setups, but they’re only as good as the fans attached to them. Let’s dive deep into the world of 140mm radiator fans and their significance.

Role in Cooling and Overclocking The primary purpose of radiator fans is to dissipate heat by drawing cool air through the radiator’s fins. Especially for those who overclock their CPUs or GPUs, an efficient fan ensures that the system remains stable under intense workloads.

Crucial Features in a Radiator Fan

When hunting for the best 140mm radiator fan, several factors come into play:

Airflow and Static Pressure While airflow, measured in CFM (Cubic Feet per Minute), indicates the volume of air a fan can push, static pressure, measured in mmH2O, signifies how effectively it can force air through obstructions like dense radiator fins.

Noise Levels Nobody likes a jet engine next to their ear. Thus, considering the noise level, measured in dBA, is essential for a pleasant computing experience.

Durability and Design Premium fans often come with high-quality bearings and materials that extend lifespan, and some also feature aesthetic touches like RGB lighting.

Top 140mm Radiator Fans

Without further ado, here are some standout 140mm radiator fans:

Noctua NF-A14 PWM Renowned for its performance and ultra-low noise, Noctua’s offering is a darling among PC enthusiasts. Its brown and beige color scheme might be divisive, but its cooling capabilities are universally acclaimed.

Corsair ML140 Pro Harnessing magnetic levitation technology, this fan provides excellent airflow and pressure while maintaining quiet operations. Plus, its customizable RGB lighting is a treat for the eyes.

be quiet! Silent Wings 3 As the name suggests, this fan prioritizes silence. However, it doesn’t compromise on performance, making it an excellent pick for both radiators and case cooling.

Fractal Design Venturi HP-14 This fan boasts a perfect balance between noise and performance. Its sleek black design makes it suitable for any PC build.

Installation Tips and Tricks

Positioning for Optimal Cooling Consider the airflow direction in your case when installing. Typically, front or bottom-mounted radiators intake cool air, while top or rear ones exhaust hot air.

RPM and Fan Curve Adjustments Utilize motherboard or third-party software to customize the fan’s RPM. Adjusting the fan curve ensures efficient cooling without unnecessary noise.


Choosing the right 140mm radiator fan can markedly improve your PC’s performance and lifespan. Investing in a quality fan ensures your components remain cool, even during the most intense computing sessions.

Frequently Asked Questions

  1. Are 140mm fans better than 120mm fans?
    • Typically, 140mm fans move more air and can be quieter since they can achieve the same airflow at lower RPMs. However, compatibility with cases and radiators should be considered.
  2. Can I mix different fans on a single radiator?
    • It’s not recommended, as different fans might have varying airflow and pressure, leading to inefficiencies.
  3. How often should I clean my radiator fans?
    • Ideally, every 3-6 months. Regular cleaning ensures optimal performance and longevity.
  4. Does RGB lighting affect fan performance?
    • No, RGB lighting is purely aesthetic and doesn’t impact cooling capabilities.
  5. How many years do radiator fans typically last?
    • Premium fans can last 5-7 years, but this varies depending on usage and the fan’s quality.
