1) The fan on heatsink must be 40x40x10mm but the fan for layer cooling can be 40x40x20mm (which is the one I've got on my printer).
2) Unfortunatly, I never used Solidworks so I cannot help
3) Yes, I only published CAD files for the "sensor-less" so people can build their own support on it. it's useless to use 40x40x20 fan on the heatsink and I even fear it will burn quickly as it won't be able to push its huge amount of airflow through the heatsink.
