I have a box with a pair of ATI Radeon HD4850s. These bad boys, when in CrossFire mode, overheat like the Phoenix summer. My two options for cooling are more fans or watercooling. The case is already loud enough just keeping the CPU cool so I am opting for trying my hand at water cooling. Besides, couldn't hurt to get the CPU a smidge cooler as well.
That being the case, what are the BEST options for water cooling these two cards. How about the cards and the CPU (Core2 Duo)? What about if I am on a budget (which I'm not but others might be)? Is there an air cooled option I am missing?
