MakerGear M2 V4 extruder and dual fan kit

I have found improved extruders and I've found improved fan assemblies, but not a solid combo unit for the MakerGear M2 with V4 hotend. This also allows you to upgrade the fans to 40mm Noctua units. www.amazon.com/gp/product/B009NQLT0M/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
This runs quiet, allows for easy assembly, gives plenty of clearance over the bed with the angled fan unit, and prints with minimal supports.
