It effectively just reduces the junction-to-heatsink thermal resistance, allowing you (in theory) to use a less efficient heatsink (or have the CPU run cooler with the same heatsink. The downside is they they're relatively inefficient - your power supply will need to supply an extra 3-4A at 12v and you need to dissipate that extra power. Unless you significantly improve the airflow through the case, you'll probably find that the internal temperature rises significantly - further stressing everything except the CPU. Note that the chip that most needs cooling may not be the CPU - the big support chips can also run very hot.
