Direct cooling 40mm Fan duct for Ramps a 40mm fan
The lower section shares mounting bolts with your arduino. Spacing it 3 mm away from the mounting surface (good for mounting direcly on to metal frames).
There are 2 different lower section with regulartor duct and without. If you choose the first yo may use the L shaped deflector to increse the airflow over the regulator. 30% of the air flow will go to the voltage regulator.
The top section Funnels air to each driver and mosfet. Each hole diameter is adjusted to flow match them.
Thanks!
06/03/15 added a new lower section with bigger ducts towards the voltage regulator and airflow now also goes below the arduino to cool the thermal pad under the voltage regulator .
