no no no, you must not have seen the previous pictures and posts. they are mounted on 120mm fans behind modders mesh from www.mnpctech.com <------(blatent plug) hehe. after that, i mounted the diamonplate on risers so that the airflow is not being constricted at all. all the air can come out on the sides. also the big thing, is that the fans are not sucking in, but blowing out. the whole system sucks from the bottom to the top as convection happens.Unknown-One said:what are those cones anyway? Dont tell me you stuck nosecones on 60mm fans And if the fans are bigger, that tiny little hole has to be restricting airflow.
