Just for kicks,what case are you using? The memory cooler will work fine,but I'm a little curious what your case cooling is,usually there is no need for dedicated mem cooler unless your doing some real heavy overclocking.Reason I ask is some better case cooling might do you better for your whole system,not just your memory,especially if you plan on overclocking your cpu and onboard graphics.
currently my computer lies on my desk, as i'm reseating the cpu and stuff,
so i have better access.
i directed a 120mm fan towards the dimms, so that it pushes through between the dimms,
result: better touchable, but still very hot, when running prime for like 30min.
and this is more active cooling, than a case airflow.
so the rams definately suck.
