1) not sure what you are asking. What issue are you referring to?
2) look at the back of the card, you will see the thermal pad through the backplate.
3) noone can tell you what to do, that is up to you.
EVGA didn't cut corners. They have been using the same design for years. The only change was the fan speed being much lower than normal. Set the bios to the slave bios switch and your card will be fine. I'm using an FTW on the slave bios and have zero issues with the fan running at 50% rather than the master bios 30%.
