I am looking for, good fans, and a general guide on how to mod your case in order to attach aditional fans, i would also like some recomendations on a good heat sink, and fan for the processor. the current system is this, http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01070885&lc=en&cc=us&dlc=&product=3453995&lang=
but i just ordered the new radeon 4850, and a Rosewill Stallion Series Dual Ball Bearing Fan RD500-2-DB ATX V2.2 500W Power Supply, for it but i am looking to overclock the processor so i need to increase the cooling of the whole unit.
these are the only good fans i know; zalman ZM-F3 LED & Antec TriCool 120.
good heatsinks are ocz vendetta 2, freezer 7 pro, zigmatek something
look through the forums, theres lots of "which heatsink" posts.
