I personally think all the different methods of cooling would make a better science experiment. From air, clc's, custom water, TEC's, refrigaration, ice, and maybe even some dry ice. Combined with tempertures and overclock potential and how the overclocking affected performance for each different method.
Judging from your componets it would appear that you have the funding for such a project. I'm also confident it is not above a 13 year olds skill level, take a look at manofchalk he is about your age and one of the top members here with lots of watercooling experience. To get an idea just how interesting cooling is take a look at the below ambient sticky as well as the one on TEC's. Very fun and interesting stuff.
Good luck with your project.
Thanks very much! I appreciate your help!
