There is still a fan with blades in that gizmo; it's just hidden in the base.

I can't imagine those "bladeless" fans having much static pressure for use on a heatsink.

coolermaster excalibers are metal and do push quite a bit of air, but yeah, i agree with everyone about the expense and weight.

Because the thermal conductivity of a metal fan (referring to the blades) is extremely poor. There is little contact between the blades and the mounting part of the fan, thus, poor thermal conductivity.
