All those benchmarks are at 100% fan though which is terribly noisy.
I have a 9700, and wow is it loud at 100%, for me at least.
If its on low, its ultra quiet however.
But, performance would certainly make a difference when set to low.
Performance may have an impact between coolers when all set to low also, and that is what I guess most people would run at. I don't want a turbine engine sounding thing in my computer
