Enermax has released 5 new fan models that use their new patented APS (Adjustable Peak Speed) Control technology. What this new technology does is it allows you to set the peak speed of the fans yourself so they will never go over a specific RPM speed. Then the speed will be regulated by a PWM or an integrated thermal sensor. The 5 new fan models include Cluster Advance, Everest Advance, Magma Advance, T.B. Vegas Quad and T.B. Vegas.
