temperature sensor controls the fan speed. The fan is always on when power is
applied to the router. Under most conditions, the fan operates at the slowest
speed to conserve power and reduce fan noise. It operates at the higher speeds
when necessary under conditions of higher ambient temperature. <o:p></o:p></span></p>

<p class=MsoNormal>What is the quietest router possible that supports
CME? I want to run CME at my house but prefer to keep the fan noise
to a minimum. <o:p></o:p></p>
