What do you mean open the heatsink and reseat it? Sorry, I'm a complete novice when it comes to this! Do you mean the fan on top of the actual Intel processor? The card itself is enclosed so I don't think I can do anything there?
When it comes to the card, will the high temperature melt the insides, or should it be OK?
Thanks for that dipankar -- but where is the heatsink for the card? There is a foxconn heatsink of the motherboard -- do you mean this? This has been there since I bought the PC though, so I wouldn't think it would be this?
