It's hard to believe, but the 9500 is Zalman's first CPU heatsink to use heatpipes. They're no strangers to heatpipes, having used them in many other cooling devices, such as VGA and HDD coolers; never before in a CPU cooler, though. But the waiting might have been worthwhile. The CNPS9500 could be the most sophisticated implementation of a heatpipe HSF for CPUs we've ever seen.
