it can be the difference between having a world record overclock, and not having a world record overclock.
Also, phase change units, unlike water or air cooling, tend to have a discrete limit to how much heat they can transfer at once.
while water and air are less efficient at pulling heat off the CPU per given surface area, their heat dissipation fits a curve. the hotter they are (especially relative to the air and/or water temperature), the more heat they dissipate at once
It should look roughly like this:
the water and air cooling lose efficiency when their temperature approaches the ambient room temperature
but the phase cooling has a ceiling.
The better the phase cooler, the higher the ceiling
