Is there a simple answer??
If you have the unlocked BIOS and are using Afterburner 2.2.3, then you are increasing the voltage. Software doesn't read the voltage correctly, so if you have the right BIOS and AB 2.2.3, then you'll see temps rise, guarenteed

1. Is it possible to hurt your card with +300% Power limit and +100mv.(which is the max of the unlocked Bios)?

These cards stay pretty damn cool for a very long while. I remember my 570...I would set it to 950mhz @ 1.1v and do a 3dMark11 run and the card was into the mid-to-high 80C's. Now with my Lightnings, I can run 1430mhz @ 1.36v through it for a game at 99% load for an hour and only hit 63C. So, temps are much easier to combat than on Fermi, but as for the voltage...we've been told by Nvidia that the chips are very sensitive to voltage increases over 1.175v, yet of all the people here running way
more than 1.175v, we've had no one report that they've fried/killed one of these from stressing it too hard, and these have been out since late June (about 7 months).
So, it's really up to you how comfortable you feel overvolting it. But I say that if you don't need to, then don't. But if you have a demanding game, don't hold back either. The chip will more likely than not out-live the warranty anyways. I haven't been pushing mine because I usually use SLI at stock clocks. But when I need one card for a game, and push it, it's still as stable as the day I got it, and temps are just as amazing
Sorry arnie, no clue what's going on with that. If I had that problem, I'd be doing the same thing you are Edited by dph314 - 1/26/13 at 5:44am
