That is a tough question. I see the reason for concern. I would like to say that it would fit but that is only a guess.
May I suggest the Gemin II Cooler Instead? I helped a friend pick it for his mini-atx case and it fit just perfect. It's low profile structure was very ideal and it cools great. It is basically a CPU heatsink with a 120mm cooler just like the evo. It would probably provide close to the same results. I feel the EVO would beat it out but I am not sure if the difference would be appreciable.
