ya i think i was lucky although not completely sure as some game are "jumpy" like cod, its not like really bad or noticable that much but i notice even if its so slight and DC universe is lagging as hell but alot of people have that and star trek online says driver isnt right or something to turn on certain graphic options (although i force them on now) but other games work fine so might be the damn windows 7... anyways the card is supposed to be able to handle the 105C temps but that is its max so not recommended i think lol but with the new fan system its always at 42-50C so well below that but still the game makes my card go 50 where others make it 45 so if you dont have custom cooling my advice is:
KEEP AN EYE OUT FOR TEMP!
(always run with V-sync as i heard that SC2 didnt have that and fried tons of cards but i dodged there to then i guess but i always force it through control panel or through the driver its self with nvidiainspector)
Ya the best thing that happened for you is that you noticed it before it went to far. The day it happened to me it went so far that ingame I noticed green graphical artifacts appear randomly across the screen... just from years of experience I knew what i was seeing is overheating. By the time I alt tabbed to inspect the temp it was 105c.. its quite possible in that few second hang time during alt-tab it dropped a couple degrees lower.
Needless to say 550 dollar mistakes make me angry.
I blame it all on my forgetfulness to switch back on the forced vsync setting.
I was playing the game just now on my new card with max settings and it seemed to sit around 60-63C. This to me is a comfortable range for a extremely graphical game.
I am running my fan temperature gauge through my G19 keyboard now a days so I can constantly monitor my temp while I am in game. It helps reduce my need for alt tabbing anymore.
