Version 1 (V1) is a single 40mm fan solution. Fan runs all the time, cooling the hotend and print bed at the same time. Some warping occurs because the initial layers of the print area are cooled.

Version 2 (V2) is a 3 fan solution. It uses a 40mm fan to cool the hexagon hotend, while two smaller (either 30mm or 25mm) fans cool the print area. The 40mm fan can run 100% of the time while the two smaller fans can cool the print area. This allows the small fans to be controlled by your gcode making sure you get the best prints.
