Summary

Replace the original 40 mm fan with a much more powerful 60x60x25 mm blower. Combine with http://www.thingiverse.com/thing:367602 for great results :-)

The blower I used is a Nidec GAMMA 27 that I found in a local surplus store. It is possible to find it on eBay as well, but I couldn't find any datasheet so I am not sure if it's really standard ... Plus, although the mount holds very well and has no play, when the printer shakes back and forth (when doing a zig-zag infill between two close walls for example) the rotor inside the blower moves around and makes "clack - clack" noises. Once again, not sure if it's inherent to the design of these blower fans, or if it is because it's a low quality one.
