Yewen said:Normally you don't need the top blowhole filled at all and are better off with just the 120mm / 120mm fans.
The blowhole only comes in when your running SLI overclocked and bank full of hard drives really.
Just the 2x 120mm will do; the case will come with some but the Amber fans are better.
kk, I like the ambers myself too, got loads around the place including 2x80mm and 1x120mm in my home made case .
