If you plan to use this for printing PLA it probably will not work. The issue is not with PLA layer cooling so much as it is cooling the throat of the extruder. A fan blowing across the print area in this fashion will not cool the throat enough and you will still get swelling and jams. You should look as Scobo's thread. He did a very easy mod by adding a few heatsinks and moving the existing fan slightly lower and is now able to print most filaments.
Of course layer cooling is important as well for PLA but this set up will still not accomplish that either. All you will do with this is keep the inside of the printer at room temp and make the entire print cooler then the last few layers laid down which will cause warping probably.
But since you have it planned this far go ahead and try it. I might be wrong.
Searching the Scobo's thread without success. Could you add here a link to that mod?

After all else failed (6 times) when trying to print a small pointy part I put a fan in the Da Vinci blowing across the bed and printer head. It worked. No curling. No lifting. No deforming. It worked great.
]]>@ horto89 I printed the housing today. Once I get all the fan parts LED and other bits I will let you know and do a post. I couldn't be bothered altering the original part as its only 1 wire out so I will just get my drill out and do that
To make it easy I just got one of these http://www.amazon.co.uk/gp/product/B00 … 1Q3IN4TG2S a switch and an adaptor to plug in the wall. Sorted. You really need a good draft to print something in PLA with lots of pointy bits quickly.

I was going to just print this and drill a hole for the line out to USB . LED space would be tight but if I run them round the edge I could probably fit a small strip either side
