The top fan is fine, but you will run into a very tight fit (possibly interference) with the side fan. Is the side fan an add-on? I don't see it as factory standard.

My system has the i7-920, Cooler Master HAF 932 case, Cooler Master V8 cooler. The Haf 932 has a side fan which just clears the V8 cooler by about 1/2"
