120 mm vs 80 mm fans... Is there such a big difference between these two? From what I hear the 120's makes less noise but when comparing 3x120 front, side and rear and a 3x80 side top and rear which makes more noise or cools the computer more?

What if it was 2x120 rear and front vs 3x80 side rear & top

120mm fans generally are quiter and shift more air because of the lower rpm and bigger fins. Id probably choose the 2x120's over the 3x80's....but it depends on what fans they are and the spec of them and whether you'd prefer cooler over quiet, or quiet over performance.

120>80 but 2 80 > 1 120

Quality over quantity. Everything will depend on the specs of each fan. 2 low-RPM 80mm fans will not beat a slightly more noisy and faster 120mm fan. If I compared 2 of my 80mm fans to one of my 120mm fans then the 120mm will win easily.
