I wish my shader would go higher but I get artifacts at 1435, which limits my core at 725. Since I back the shader down to 1420, my core has to come down to 710. This gives me a final overclock of 710/1420/2500 on my Superclocked GTX 260 core 216.
I just keep the fan at the default 40% and have never gone over 76 underload, and I idle at 42. If I run the fan at 100% I peak in the low 60's with my overclock and idle in the high 30's.
Wow. That's a great OC on your memory. Btw, do you link the core and shader clocks? Just curious because you say your shader clock limits your core. I personally do not link them. I do link them initially, but once I reach my max shader I then unlink and push the core up a bit. I have to watch my temps though when I do that. My card runs a little hotter than yours, so temps is a great concern of mine.
