Hi all just built my new tower and my HIS radeon x1650pro 256mb GDDR3 is over heating I think. It is lagging up in games and it becomes extremely hot. I have good fan flow in the case 80mm in 120mm out and the cpu averages 38c. When the card get super hot my desktop background is all granular and it goes away when the card cools down. I'm I screwed with this card since the heat sink/fan takes up one pci slot, do I have to install a pci fan too? Any thoughts would be great Thanks!
