I have the evga 650 ti boost 2gb (no sc) this card have a nice FAN, but here is too hot (like 25-30°C) so I always play with the max fan spd. 3350rpm (74%) and the temp. is 67°C playing Crysis 3 overclocked to 1201mhz core and 3348 (+345) memory. But I'm worried about the Memory temp, I don't know it is safe to play all my games with that vRAM OC. I don't want to damage the memory by heat. I overclocked the vram to +500 and never show any artifacts, just a TDR.
