A rearview assembly for a vehicle includes a rearview device and a processor. A housing supports the rearview device and the processor. The housing defines a recess therein. An air moving device is operably coupled with the housing and is configured to draw air from an area exterior to the housing into the recess, thereby cooling at least one of the rearview device and the processor. 1. A rearview assembly for a vehicle , the rearview assembly comprising:a rearview device;a processor;a housing supporting the rearview device and processor, the housing defining a recess therein;an air moving device operably coupled with the housing and configured to draw air from an area exterior to the housing into the recess, thereby cooling at least one of the rearview device and the processor.2. The rearview assembly of claim 1 , further comprising:a light-emitting diode (LED) board that is cooled by the air moving device.3. The rearview assembly of claim 1 , wherein the air moving device includes multiple fans.4. The rearview assembly of claim 1 , wherein the air moving device includes at least one piezoelectric blower.5. The rearview assembly of claim 1 , further comprising:a heat pipe disposed proximate the air moving device.6. The rearview assembly of claim 1 , further comprising:a speed modulating control configured to reduce a speed of the air moving device and reduce a related noise output associated with the speed of the air moving device.7. The rearview assembly of claim 6 , wherein the speed modulating control is operable to change revolutions per minute (RPM) of the air moving device claim 6 , thereby changing the noise output of the air moving device based on a vehicle speed.8. The rearview assembly of claim 7 , wherein the speed modulating control is operable to reduce the volumetric flow rate of the air moving device claim 7 , thereby reducing the speed modulating control noise output when a motor of the vehicle is operating below a threshold revolutions per minute ( ...
