Active cooling for the ramps board?

[printbus]

... for a permanent solution I would like to figure out a mount that can cover the stepper drivers and also direct some airflow between the arduno and the plywood frame.

Or go with something like Rambo electronics that combines the Arduino, the RAMPS, and the stepper drivers all on one board that should be easier to cool. It'll be interesting to see how Rambo works out for those buying the 12-inch i3v that ships with it.

I haven't gotten around to installing the fan yet, but I printed a pair of these brackets to use with the RAMPS board - http://www.thingiverse.com/thing:145946

OK - finally got around to installing a fan with these brackets. I wanted to center the fan over the stepper drivers, but this leads to one leg that doesn't fit the edge of the board well because of the servos connector block on RAMPS. I left it that way, but a better fit would require either increasing the height of the notch in the leg of that corner or moving the fan down so that leg is below the reset button. Those without a heat bed relay should likely do the latter anyway since it'll add airflow for the heat bed MOSFET heatsink, but at some loss at airflow for the Z axis stepper motor driver.

As another option, some tweaks to AbuMaia's Y-motor fan bracket might allow it to be bolted to the faceplate of the frame and used as RAMPS fan mount... http://www.thingiverse.com/thing:498414

Installed a 50mm fan on mine today:

I don't think I see how this would work. What do you mean by "bolted to the faceplate"?

Yeah, it's a stretch. My point is that rather than hassle with the brackets that somewhat fit over the RAMPS board, all we need is a bracket that can mount the fan to the back side of the vertical face of the printer frame and suspend the fan over RAMPS. Maybe using something like the 3M adhesive tape so you wouldn't have to worry about screws or bolt heats sticking through the front side of the frame and getting in the way of the wheels on the vertical rails.

There are RAMPS fan holders like this http://www.thingiverse.com/thing:138007 and http://www.thingiverse.com/thing:428066 that clip onto the angled part of the wood frame.

I'm running a used 80mm fan with a bracket I drew up in blender. Mounted it below the RAMPS slight angle forward blowing up on the RAMPS. Drilled holes on the side to mount.
