Wrapping the PSU in thermal paste plus aluminum foil is going to cool it down less, not more. If you really want to get creative, cut out two square holes at opposite ends of PSU plastic (voids warranty) and use its 19V output to drive two 6-cm 12V fans in series circuit, one blowing air in, one sucking air out. They'll draw around 1.5 - 2W and cool the PSU all right. The problem being that if the PSU overheats, then it is underdimensioned (e.g. a 65W with a laptop occasionally drawing 70-75W) and should be immediately replaced with a more powerful one. The overheating is a symptom.

Thank you Lserni. I guess thermal paste only works between metallic surfaces or between certain alloys.
