^^ya I read the manual, but two reasons i'm actually getting the board for x-mas so haven't had a chance to read it yet, two, I didn't know what passive cooling was...
DO NOT put the fans on. It will interfere with the airflow on the CPU fan. I've got a Asus board as well and when I was installing everything I came across that. You only want to use those if your using a passive or watercooled system.
The asus board I posted a link to has passive cooling...
O ok now I get it, its saying use it if your using a passive cooling system to cool the cpu not the mobo, sorry for the misunderstanding.
