If you want cooler that can give you 20c likes his hsf then get zalman 9500 im sure it will cool the same.
You think a zalman 9500 can pull a low temp like mines? I dont think so. I know its not zalman but its this one fan I cant remember the name. here are the temps.
Does that help at all?
And I have it overclocked 100mhz higher
those temps look nice tbh but when i look at the voltages.. they seem a bit low, do you have a AMD processor? ( Cool 'n Quiet )
