I like it but how would we make the fans spin backwards? Simply reversing the voltage to the fans only works with permanent magnet motors from the limited testing I did a few years back.Quote
NumberSix
One possible solutions might be to be able to control the fan direction. They can cool the heat-sinks when air flows in either direction (we can debate which direction cools better), so when you are first printing you suck air up, then when you want to cool the work you blow air down! Just a wacky suggestion!
