I was starting to think it was a thermal mass issue.  I have extensive 
experience repairing/soldering a wide variety of electronics, including 
$million Mass Spectrometers, but never a PCB as hefty as a GPU.  I do 
have some ancient PCBs to p

I do have a nice heat gun, so I'll just need to set up a bracket/clamp
