Oh well, my friend Ramiro left me speechless. After 4 months of testing he put together a comprehensive article about twin-tower architecture. Unfortunately it's in Romanian but here you can go through Google translate.
You have all kind of tests, in case/open stand, from low TDP to extreme TDP, 775 vs. 1366, from fanless to extreme CFM, a study of each heatsink, a study about each heatsink mounting system, an extreme test NH-D14 vs. TRUE Copper with MX-3 and Liquid Pro and more.
If you have some questions about the article shoot and I'll try to answer/translate.
