My 3770k's currently housed inside an Antec Twelve Hundred.. the big ones. And while I used to have a lot of drives in it.. I now have just 3 mechanical drives near the top and 2 SSD's, so about 80% of the front 3 x 120mm intake fans are almost all open now, and the side intake fan.. and it has the big like 240mm exhaust up top. It gets.. excellent airflow.
And I would show you my fan profile but my 3770k's dead in the water right now, ram failure yesterday (I have more on order). But the basic jist of it is I have a rather aggressive fan profile with it hitting 100% fans at 80c, and near 85% - 90% at 75c. Loud but.. I usually have a window air conditioner going and games turned up over that so I hardly notice it (Texas gets -HOT!-).
