The thing covers two of my ram slots on my P67A-UD5, would it be ok just to use one fan, the output one as im a bit stuck here?
Thanks

I always assumed the first slot, the one closest to the CPU was slot 1, however I checked CPU-Z to find it turned out to be slot 4 or something. So, for me at least, the second slot from the CPU was slot 1. Might be an idea to check CPU-Z and see if it is the same for you. My mobo didnt have any markings on it to indicate which was which.
