Delta Electronics / Fans E-Series GFB/PFB High-Performance Axial DC Fans

Delta Electronics E-Series GFB/PFB High-Performance Axial DC Fans feature an advanced communication design with higher fan performance at fail mode and a fan turbo function that can be started automatically. The E-Series DC Fans consist of the dual rotor fan GFB series and the single rotor fan PFB series. With an improved CPU thermal design power of up to 300W+, the axial fans also provide a decreased fan reverse speed and a reduced flow leakage at fail mode. Other features include low power consumption, low rotating vibrations, and airflow path optimization.
