Method And System For Cleaning A Fan Inlet

A method of cooling a device comprising:

• providing a housing;
• providing a first fan having a first inlet and a second fan having a second inlet, the first fan and the second fan mounted in a wall of the housing, the first fan and the second fan oriented to draw air into the housing;
• providing a device in the housing, the device positioned to receive airflow from the first fan and the second fan;
• and
• providing a controller for controlling the first fan and the second fan, wherein the controller is configured to initiate a cleaning cycle during which the first fan is on and the second fan is off to cause backpressure airflow to flow through the second inlet in a reverse direction for a first time period and the first fan is off and the second fan is on to cause backpressure airflow to flow through the first inlet in a reverse direction for a second time period.
