The major downfall of this CPU cooler, as mentioned above, is that it will not fit in a case where a user has RAM modules with tall heatsinks installed. And seeing that this is an enthusiast cooler, it would seem pretty obvious to assume the user buying this cooler has some fance RAM modules already.
Also, the rating of 5/5 seems wrong as there is some key faults with this cooler - so, how can something achieve 5/5 whilst still having some obvious limitations? That means the scoring means nothing at all?
