Snip: The Arctic Cooling Alpine 64 heatsink suspends its 2000RPM fan on four dual axial rubber vibration absorbing posts.

The 90-ish millimeter fan minimizes turbulence and noise by essentially floating the impeller alone above the aluminum component. The whole package weighs in at just 486 grams, and judging by recent information the Arctic Cooling Alpine 64 should even be compatible with AMD socket AM2 heatsink retention frames… though we aren’t 100% certain.
