^^ +1.
common guys post some benches and make this thread active.
I think, we should make a thread or guide or even instruction , how to overclock safely. bcoz many of them doesn't know the way or afraid of warranty or maybe not interested .
Guys, I reached 1050/1400 MHz stable clocks. Max load temp was 66 C and idle was 30 C on afterburner. Ran 3 loops of 3d mark vantage xtreme preset. Will post a screenshot tomorrow. Score was around X11xxx.

Question: Is GPU fan RPM under full load around 70% okay or should I reduce it?
^^ there's no such thing as running a gfx card at highest possible ( read 3D clock speed ) clock speed 24*7 unless you flash a moded bios - use at-least two profile for OC and normal mode - before using any gfx intensive ap ( like any D app, game ) switch to OC/Performance profile and once yu finished your game just switch back to normal profile - the gpu clocks will be automatically reduced and talking about fan speed : you can set different fan speed for different temps.
