Well according to Newegg forums and other specs. The average video card depending on the case idles around 55-65 and t hen plays at 70-80. This card supposely runs hot and only damages at 90+. Though like I said it never went above 75 and now with Ntune with Nvidia. It never goes above 70 now. 
EDIT:
I take that back, after more research, 90-120 C is the danger zone. 80 can cause minor problems but 90-120 is bad.
