Narrative:

Avionics ventilation fault on the takeoff roll. Continued the takeoff. After we cleaned the aircraft up we followed the ECAM & QRH the fault did not clear. Contacted maintenance control who advised use to pull 3 circuit breakers and recycle the blower/extract fans. The fault did not clear. Maintenance control advised us to return to our departure airport. Burned down to landing weight and preformed a routine approach and landing. Pulled into the gate. Shut the aircraft down and preformed a post flight walk around. The aircraft had the MEL class ii; I believe that's close. At any rate I think that is what caused the avionics ventilation fault. Maybe take a little more time and fix the problem instead of just putting it on MEL. I have been on the airbus for 9.5 years and I have never seen this type of class ii fault.
