Nice thing about the EVO, the fan height is adjustable, I am running Tridents and had to raise the fan a quarter inch or so with no ill effects, with my 3570K at 4.7 24/7 still idles in low 30s
In general, no you won't have a problem since there is a limited amount of RAMs that could create clearence issues. But just in case, could you tell me which motherboard and RAM you're using?
Actually there are a number of sets of DRAM with big heatsinks, that play havoc with many coolers, however as mentioned the EVO is adjustable, to leave the fins on my Tridents, I just raised the fan about a quarter inch
