Even if we had super conducting materials (i.e. no current leakage and no problem with heat dissipation), there's still the physical limitation of scaling transistors beyond a couple of atoms (the wall) as well as the constant speed of electrons - 3GHz means impulses are 100% out of sync after traveling just a couple of cm. Heat is more an annoying consequence of CPU's effectively being over-clocked from the manufacturer today (remember when a 486 or Pentium required just a tiny heat sink?).
