Here's what I'm worried about. I bought the Radeon X1900XT off of newegg 2 days ago. I'm wanting the thing to last for 3 years. The heat worries me, though. I'm worried that the X1900XT will die on me due to the heat it produces and I want some assurance that it won't and I don't like the Idea of buying aftermarket heatsinks. I bought a case with 2 120mm fans that do 110CFM airflow. Will that keep my X1900XT cool or am I screwed?
