New GPU overclocking help


I just had just gotten a ASUS GTX 780 DirectCU II, and I was wondering, for overclocking, what would you let the temperature not go over?

it'll still work until around 100c (nvidia says 95), but most people consider a max safe temp to be arround 60-70c

Im not concerned until about 85c, i believe most manufacturers set the bios to push the fans too 100% when the temp exceeds 95c and most likely shutdown around 100c
