Welcome to the SeeMeCNC Community

I was thinking of using an old Pentium 4 cooling fan and heatsink on the extruder motor.... like this one : http://www.telecommander.com/pics/links ... 423fan.htm I was thinking arctic silver to mount it to the back... since I have a V1 soon to be in an enclosure I was also thinking about moving the extruder on top of the printer to keep it cool.

any thoughts would be appreciated.
