Im thinking it would be safer and cheaper in the long run to put one of these under the card for some additional cooling.
A large amount of the posts here that deal with bad video is due to voltage problems.
So I would be unsure if what you want to do is a great idea.http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=2010110573%201372526581&name=PCI%20Slot%20Case%20Cooler
Putting one of them under the card is sometimes counter-productive. They are exhaust fans, not intake. They do not blow fresh air onto the card, but rather pull air around the card away from it. Sometimes the air they pull out is already cool air, supplied either from a vent or intake fan. It's that situation wherein these coolers are counter-productive.
To the OP. Best to stay away from messing with that sort of thing unless you can afford to brick the card.
