GPU undervolting increases temperature?

[NightmareWokeUp]

Hey guys, so I just upgraded from a 1060 to a 1080 since the price was great. I let afterburner do it's OC scan magic to get the best bang for my buck. However the card is constantly hitting 83c (temp limit) so I thought I'd undervolt it...
Opened up the frequency/voltage graph, chose a point (approx the clock speed where the card was hitting temp limit) and dragged all the points right side of it down to the same clock speed to set my max voltage to 1V. That worked great, card wasnt exceeding 1V anymore, but somehow it started exceeding the temperature limit by a lot, im talking 94c here, even though the limit was still set to 83c. The card tried to compensate for it, even dropping down to 1600mhz 0.8v but still being wayyy above temp limit. How is this possible, any clues?...

 

Thanks a lot.

Does temperature go back to normal after you reset the whole thing?

 

btw you can undervolt by reducing power limit before increasing core clock offset
