In this case, the laptop is technically defective. Either the power management drivers, poor application of heat sink compound, a leaked heat pipe, or crud built up in the heat sinks. Or just bad design, depending on the manufacturer.
The heat pipe is an interesting culprit - I recently ran across a laptop that the fan ran at high speed on all the time, but the case and heat sinks at the exhaust ports were not hot to the touch. It turned out to be a heat pipe that had lost its cooling fluid, so the CPU was running hot, but the rest of the heat pathway was not conducting the heat away at all.
