Personally I like having a manually controlled fan speed curve.
I found that on my GTX470 it would run under full load with factory fan settings at 65%% fan speed at 94C.
Using a manual curve I run under full load at 75%% fan speed at 75C.
Almost 20C cooler temps for an additional 10%% fan is worth it, in my opinion anyway.
