Guys, I know this has been asked before...but...I still have some questions. Heres the deal, I just got a 7800gtx that runs hot as hell on the stock cooler. Im talking it idles @ 54c and loads @ 75c! This thing is thirsty! From what Ive read a lot of folks dont think the DD NV-78 is worth the extra coin to cool the ram. My deal is , i dont have a great deal of airflow in my case ( praetorian w/ 2 80's up front and 1 @ the top). If I do decide to go passive on the ramsinks , what GPU block would you guys recommend? I was looking at the silverprop fusion, and the maze 4.I need something with 1/2" barbs. Any other options? Im using an oldschool apex kit(storm, d5 pump).Thanks in advance guys!
