I have a Nvidia TitanX in my HTPC, which is known for its high heat output, and it keeps overheating when I play 3D games. The case has two intake fans on one side and two exhaust fans on the other, but lacks ventilation on the top panel. I'm tired of the random shutdowns during game play and was wondering if anyone had any recommemdations for a more efficient GPU.
