Some people with a conscientious streak out there doing testing with typical overclocker gear. The key is to have a clear goal and to keep in mind that there are many interrelated parts that are involved in "whole system testing" that people like to see:
http://www.overclockers.com/articles546/ Note the emphasis on mounting and subjective properties, and note that Hoot controls ambient air temp AND water temp by adjusting the voltage of his fan. Hoot is trying to test a block in a system not test the overall system.

In all cases note the lack of mention of replicates or the possibility in errors in measurement.
