I can crank up this Asus cooler to full speed (2250rpm) and drop to similar temps on the B3 with 25C ambient. Not bad for a B3 at 3.0 from what I have seen. With the CPU fan controled by the mobo, around 970 idle, and the chassis fans running at 900rpm, the idle is 47-50C and 67-70C load at 1700rpm cpu, 1000 chassis.
And on topic, everything I have read points to the Ultra Extreme. I would get one of the Scythe 800120mm S-Flexs or a Noctua 8db and leave it full bore (no choice because neither is PWM). There aren't any "silent" PWM fans on the market.
Medium (1600~ rpm),on high (2160~ rpm) it only lowers the temps by 1c at idle and 2 to 3 on a full load.Running it on low,it cannot be heard,and temps only go up a few degrees.Low on this thing is about 1000 rpm.
Its a little too loud at full tilt,so I leave it on low.
