This enables effective cooling performance in compact server chassis and dense heat sink environments. An optimized impeller design, incorporating a leading-edge chamfer and integrated vent structure, improves aerodynamic efficiency while reducing noise, vibration, and motor temperature. These enhancements contribute to stable, high-speed operation and improved thermal performance during continuous workloads. For long-term reliability, the GT JET 8080 is built with a dual ball bearing system, engineered for high-temperature, high-speed, and continuous operation. An integrated copper tube structure further enhances motor heat dissipation and shaft stability, improving durability and cooling efficiency under sustained high-load conditions. To support modern server thermal management requirements, the GT JET 8080 supports PWM intelligent speed control, enabling precise fan speed adjustment based on system thermal demand. Optional fault feedback functionality is available to facilitate system monitoring and seamless server integration. The circuit design already includes hot-swap functionality.   Specifications Model (TYPE A) Rated Voltage (VDC) Rated Current (A) Power Consumption (Watts) Speed Inlet/outlet (rpm) Air Flow (CFM) Static Pressure (mmH2O) Noise (dBA) GT-A08080B12U 12 5.13 61.56 14,600 / 12,300 149.01 137.9 75.87  1.
