Silent, Long-Lasting 135mm Fluid-Dynamic Bearing fan with ECO MODE

The ultra-quiet 135mm Fluid-Dynamic Bearing fan becomes silent when coupled with EVGA ECO mode to turn off the fan in low to medium loads. The larger fan and carefully tuned profile creates a quieter experience than the B3 power supplies.
