Your work is nice but the incoming air is pointed directly at the face of the rotor which will lead to the inward side being cooler than the outward thus causing premature thermal cracking. The better setups (from what i have read) are directed to the very center of the rotor - not the face. Forcing air to the inside and through the vents will cool more evenly. Take a look at the attached pic. Also, you might consider one duct to the rotor and one to the caliper. Cooling the caliper will help with the boiling too. What spindle are you running?
