the best thing you can do, if you must fry your card, is simple 2 things:
1) remove very shitty gpu heatsink & fan - replace with cpu heatsink & fan (amd ones are nice) just hold it to your board with zip ties or something that will be able to handle ~80`c
2) get a casefan and glue it onto or near your card blowing onto it - i had an old 8600gt with silentpipe (inadequate) and with a casefan reduced temps by 15`c - i cut out a cd spindle cover & put fan into it, cut holes in side for airflow, put fan+stand in bottom of case pointed at card.
