I got the Corsair Dominator GT 4Gb 2000Mhz 8-8-8-24 set, what could be wrong with that you might ask well.
This is a weird problem as other people that own a Corsair dominator airflow fan might know of the crappy mounting system.
It is hold into place by two brackets over the clips that hold the memory in place.
Here's the deal my motherboard (ASUS maximus III formula) doesn't have the clips on one side.
So when I mounted it, it just is not fastend shut not a big deal in a normal case aswhere a memory whould be positioned verticaly and it would just hang, however i have a rather special case (Silverstone Raven 01) where the MB is twisted 90degrees
and the memory fan now horizontaly just plain simple slides of WHAT TO DO...
i would say some brackets of somesort but i don't know...
I have the same memory and motherboard as you. I too would like some way of having the ram mounted from both ends rather than one. I have not been using the fans since I got them but I may have a look tonight to see what I can purchase to mod it in place!
