Best Reverse Blade Fans [120mm and 140mm Reverse Fans]

Reverse Blade Fans are one of the latest innovations in the PC Cooling arena. As the name indicates, reverse blade fans have an inverted blade design and airflow compared to a standard PC Case fan. The image below shows the blade design of a standard fan and a reverse fan.

The direction of the airflow in a reverse blade fan is opposite to that of a standard or regular fan when installed in the same orientation. Reverse Blade fans serve a particular purpose and eliminate some problems associated with regular computer fans for some specific placement or installation. The image below shows the difference between the airflow direction of regular and reverse blade fans.

Standard Blade vs Reverse Blade Fan Airflow Direction

Right now, only a few manufacturers have reverse blade computer fans, but they are becoming popular as more people learn about them. Regarding dimensions, there are more 120mm reverse fan models in the market compared to the 140mm reverse fan models. Reverse Blade Fans are also called Reverse Fans, Reverse PC Case Fans, Reverse Computer Case Fans, or Reverse PC Fans.

Why Buy Reverse Blade Fans?

Reverse blade fans can perform better than standard fans in specific locations, positions, and scenarios. Below are the main applications and usages for reverse blade fans in PC Cases, CPU Heatsinks, and Radiators.

PC Case – Reverse blade fans should be installed inside the PC Case only, not outside. The best positions for reverse blade fans in a PC Case are at the bottom, side, and front. In a PC Case, reverse blade fans should be installed as intake fans only, i.e., blowing fresh air inside the PC Case by pulling fresh air from outside.

Radiator – Reverse blade fans should be installed in an exhaust or pull configuration on radiators, i.e., pulling hot air away from the radiator and moving it to the surroundings. If you want to install a radiator at the bottom of the PC or the front (inside the PC Case), reverse blade fans will be better than regular blade fans. 

CPU Heatsink – If you want to add an extra fan to your CPU heatsink in pull configuration, a reverse blade fan will be more beneficial in terms of performance and aesthetics.

Advantages of Reverse Blade PC Fans

Below are some of the top advantages of using reverse blade fans for PC, Radiator, or CPU Heatsinks. You should note that these advantages only apply when the reverse fan is installed in the correct configuration or direction inside the PC Case or on the Radiator or CPU Heatsink.

Aesthetics & Clean Looks – Reverse fans look much better because the fan frame does not come in front of the blades, and you have a clear view of the blades and the fan center (hub). Some reverse fan blades come with fancy ARGB LED lighting and a mesmerizing infinity mirror effect (on the fan center). 

Better Cable Management – Cable management with reverse blade fans is much better than with regular fans because the cable wire does not come in front of the fan blades and gets hidden with the frame. Moreover, most reverse blade fans use pin-to-pad connectors or bridge connectors to connect with each other (daisy chaining) without the need for any extra cables or wires. The power and signal are carried by the fan at the corner, which is then fed to the connected fans using the contact points.

Easier to Clean – Reverse blade fans are easier to clean as the fan frame does not obstruct the fan blades.

Better Performance – Reverse blade fans can offer better airflow performance when installed in a pull configuration on the heatsink/radiator or inside the PC Case as intake fans. Also, some reverse blade fans are thicker than 25mm (up to 30mm), resulting in more stability, lesser vibrational noise, and better airflow and static pressure.

Can be Less Noisy – When installed in a specific configuration (intake fan, etc.), reverse blade fans can generate less noise compared to similar specs standard blade fans installed with the same airflow direction, i.e., intake in this scenario.
