Hi all! I'm currently in the process of upgrading my KP to use the E3Dv6 end effector design helpfully pioneered by our friends @Taylor and @grainiac. I'm to the point where I need to buy some fans for print cooling, and want to make sure the ones I get are properly rated for the voltages output by the end effector PCA (which I plan on keeping). Unfortunately, it doesn't look like the documentation is currently available on the kosselpro.com website (I see a godaddy.com landing page there when trying to view it). I'm pretty sure they're all 5V fans, as I measured the always-on fan at 4.99V and I'm pretty sure they're all identical. I just want to get a second opinion before I go out and buy them. The fan mount I'm looking at using is a replacement for the clip-on fan mount supplied with the E3Dv6 and can be viewed here: http://www.thingiverse.com/thing:1459589 -- it uses two 30mm fans for print cooling and one to cool the E3Dv6.
