Water cooling is only good if you really need it. Water cooling requires upkeep. You need to clean it on a 1 - 2 month basis to keep it running properly and working as intended. You should really only be using water cooling if you really need it due to overclocking and stuff like that.

As for the thermal paste.. This alone will not keep your CPU cool. You need a decent heatsink, then you also need some form of exhaust on your chassis to get that hot air out of the case.

There are many things inside your system that create heat. Mainly the CPU, then the GPU, RAM, HD's, and PSU. When you remove heat from one of these it has to go somewhere. This is why ppl build compures with either Negative air pressure, or Possessive air pressure. Depending on whether or not your GPU exhausted out the back of your machine, or inside your machine will dictate what kind of air pressure you system needs.

While air flow in the Tower is very important, what is more important is that heatsink on the CPU as it is responsible for conducting, and dissipating the main source of heat inside that system.

Any system you are going to be gaming on for hours on end will require a better than average cooling system to keep temps down and insure the life of the system.
