I have a 660ti OC from Gigabyte and when looking at the heatsink near the fan, it is slightly bent. about 3 of the "blades" are bent down. I handled my card very carefully when I installed it so I doubt I did it.
I think it's just cosmetic damage if anything.. My tempuratures for the card underload goes around 65-72C at the hottest. 30-35C idle.
What do you think?

It's actually quite common to have a few bent fins on the heatsink, from looking at your temps it seems the damage is only cosmetic as your temps are excellent.
