since i'm using a new build pc with a i7 six core on around 30°C all the time on a new GTX780 so i hardly think that is the problem.
EDIT: i just checked some things it seems i wasn't paying much attention when looking. it seems the cooler i was using is by far not good enough for such a powerfull cpu. but no worries i just ordered one with water cooling so i should be fine tomorow when it gets here
