sorry, i must admit i didnt really read the review, just glanced at the link for few sec... i guess i will do that now 🙂 you sounded new to TECs in your initial post so i figured you could use some of my previous experiences as a guiding light... oh well 🙂
EDIT
Con:
* Expensive. You can achieve similar (or better) performance from a conventional HSF, at 1/3rd the price
* Noisy stock fans.
that sums it up i supopse.. common sense leads me to believe there is no way that puny fan will be enough to dissipate the massive heat generated by the TECs (these things get insanely hot, they generate tons of heat on their own), either that or they arent using a TEC with high enough W in which case it maybe doing more harm than good...
