Yeah i've heard of the Noctua, but i've also heard its quite heavy, and have heard storys of it snapping motherboards lol. the v8 seems a bit to big for my tastes lol.. if it makes things easier, this is the selection I've got http://www.pccasegear.com/index.php?main_page=index&cPath=207_23_845 since its the site i get all my hardware from here in Australia. i have heard good things about the Corsair Hydro Series, if i was to get one, would it matter which one i go? or would the higher models cool the CPU better than the lower models. also punto, a fan came with the case at the top, however i will be replacing all fans in tower with bitfenix ones.
