Can I install 72W A19 halogen into a 60W-looking socket?
If the fan light fixture is newer and meets EPAct05 compliance then there will be a circuit in place to limit the total power to 190W. Exceeding that total wattage should cause the circuit to interrupt the current. I believe the circuit should reset itself when power is removed, load reduced, and power restored. 

However, I had one fan light fixture for which I had installed CFLs. The fixture wasn't rated for CFL use and the EPAAct05 prevention device got fried and permanently opened.
