Frostytech put this HSF through its test bench.

"Zalman's CNPS5X-SZ heatsink is an updated, vertical interpretation of a 2006-era heatsink Zalman released under the CNPS8000 nomenclature. Like its forefather, the CNPS5X-SZ fills the role of a lower profile, light weight cooler that's ideally suited to sub-95W TDP processors. It's stacked aluminum fins are connected by three 6mm diameter copper heatpipes to a small aluminum base block with a thin bit of copper covering the otherwise exposed heatpipes."
