[cisco-voip] Quietest router for CME

[Jack Martin]

The UC520 SBCS does not have any fans so it is relatively silent.

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
