Leadtek Winfast A280LE TDH

This is leadtek card is the GF4 Ti4200 with VIVO.
I just ran 3Dmark '01 SE for fun. It was on my data system. hehe It got 9543 3Dmarks and did 62.1 FPS on game four. I was just wonder if these were good scores or not. Also if anyone has this card i was wondering if they were haveing problems with the card overheating at stock. I would play DAOC for about an hour and I would lose all visual and the system would lock up. I put a fan in the side of the case blowing right on the card and now it seems to be fine.

The heatsink may not be making good contact with the core.
Your score is where it should be.

thank you. Think i should try taking it off and reseating it?
