Well if you can get the fans to spin with the TUNE menu then I suspect Cura isn't turning on the fans. Look at the gcode file that cura produces in any text editor (for example on a PC you can use notepad). gcode files are human readable.
Use the editor's search feature to locate all fan commands M106. For example:
M106 S127 <-- Sets the fan to 50% and
M106 S255 <-- Sets the fan to 100%
My fan doesn't come on until around 30% which is M106 S76. Your fan may vary a bit and need 40%.
In Cura I set my "fan min" and "fan max" both to 100%. If you set the fan min to 0% I believe it won't turn on unless the layer time is less than the minimum layer time.
