E Series Fans

E Series Fans

New Products Launched in 2021: Series PFB-E & GFB-E

Delta's latest E series fans are designed for the next generation of server architectures and power modules.
Developing at ever-increasing speeds, enterprise server processors and associated technology continue to increase power density and performance. Often times this comes with an associated increase in demand for power and heat dissipation. Delta, working closely with the industry, has created a new High-Performance fan series by reevaluating and simulating every functional component of its fan to find and improve all areas of functionality. This leads to improvements across the board in efficiency, vibration, speed, noise reduction, resonance, and safety. This is coupled with smart sensing technology to further increase the ability of the fan series and protect the costly components, these new HIGH PERFORMANCE fans are deployed to thermally manage. With the Intel Whitley platform, 300W+ and higher TDP can be expected. To manage this high wattage and high heat application, the new Delta HIGH-PERFORMANCE fan introduces fan speeds greater than 30,000 RPM while maintaining or reducing power consumption over prior generation fans, the output static pressure can reach 9.73 inH20.

With a focus on longevity, Delta has integrated a new smart communication design into this new High-Performance fan series. This fan built in an anti-reverse function in a fail mode which can reduce the system reverse airflow loss.

Benefits of Delta New High Performance Fans:

  • Highest speed fans with greater than 30,000 RPM and the output static pressure can reach to 9.73 inH20
  • Increased performance with higher power efficiency to maintain or reduce power requirements
  • Redesigned impeller to increase airflow rate and improve blade efficiency
  • The new resin utilized for the fan frame for higher flexural modulus to reduce fan vibration
  • Smart system design to assist in preserving vital server blade components
