It is all about efficiency. Your CPU puts out a lot of heat just at idle. When it is used it goes way up. The better you dissipate the heat from the die the better your temps will be. The best air cooler will not cool as efficiently as your standard enthusiasts water loop. Air cooling uses heat sinks to draw the heat away and a fan to wash away that heat. You can only do so much with an air cooler. The sky is the limit on how you want your water setup. Multiple radiators, GPU's cooled as well, multiple loops, etc. You can even put all of your radiators in a separate case and run the tubing to your system.
I used to live in Phoenix. It gets ungodly hot. Fortunately it is well known and most places have air conditioning/ If your home does not get too hot and you are not seeing very high temps you will be fine on either a quality iar cooler or start off with a water cooling kit. Be warned though, water cooling and modding can be very addictive.
