maybe it would be better to use about +/- 20 volts and use 4 ohm load(2 ohm for each tda1514)

May be you can try them in parallel mode! With +/- 23v PSU TDA1514A can drive 48W to a 4ohm load. And if u connect them in parallel u can feed them with +/- 28v. In that case they will give about 85W RMS to a 4 ohm load.

i'll put heatsink and cooler about 0.6C/W.I think this should do it.
Bytheway 0.6C/W can hold AMD palomino with 70watts dissipation.
