Each board varies (the ram slots aren't a set distance from the socket). You could get short ram that would fit no matter what cooler you get. You can also check the Newegg reviews of the products you are interested in and see if any complain of similar conflicts.
Thats kind of the problem im facing now I guess. I already have 2x4gb of Corsair vengence... its pretty tall and I was wondering if i got another dual channel set if it would fit but I'll see on newegg. Been checking around and can't find any definite answers anywhere. Thanks for your help though.
I've got some parts im still missing the main components such as case, mobo, cpu, cpu cooler, I am going to buy these from newegg all at once for the 1 month doa thing they do. I was just looking to get:
Case: HAF X
Mobo: Asus z68 pro
Cpu: I7 2600k
Cpu Cooler: V6 GT
