[cisco-voip] Quietest router for CME

[Jason Aarons (US)]

Turn your AC way down,  and the fan on a 1841 will run at low speed.  I
recall the temperature sensor in environmental monitor adjusts fan speed
just like my laptop does. Stick it in a closed cabinet and it should run
at high.

 

I want to say the old 1751V fan rarely ran and you could disconnect it's
plug from chassis, but you don't want such an old router for CME.

 

You could also cut the fan wires and let it run hot.

Chassis Ventilation 

An internal three-speed fan provides chassis cooling. An onboard
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.

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. 

 

Thanks,

Mark
