That is a nice GPU.  I would "splurge" on the new connector and just ignore the 
old one, or grind part of it away if it's interfering.

Another trick is just go to FreeGeek during one of their "pick up junk" days 
and ask if they have a fried circuit board in their scrap pile that has the 
connector you want.

I would not use a heat gun on it even a nice one.  Hot air desoldering stations 
deliver a precision superheated air stream that is fairly narrow, a heat gun is 
sort of a bull in a china shop thing.

Could you make an 8-pin molex to whatever pin you need molex "extension cord 
adapter" or run the replacement heatsink fans off some other power source 
inside of the computer?

Thanks for the suggestions.

For the curious, here is a link to the GPU with the blower/heat sink removed. 
GPUs are designed to run HOT, and the PCB undoubtedly has more thermal mass 
than I considered.

You can see the dual 8-pin Molex on the end and a corresponding spot on the top 
edge.

I can drill out the through holes easily enough, but was hoping to not have to 
purchase new connectors.
