These sorts of cooler designs have continued interest for a number of reasons.
It remains to be seen whether the heatpipes added to this model -- otherwise similar to the older "copper-flower" designs -- bring its thermal resistance into line with the 9500, 9700, and coolers by other manufacturers (like ThermalRight, Sunbeam, Scythe, etc. -- as compared in the May 4 "update" on the TR Ultra-120-Extreme).
The old copper-flower designs had thermal resistances between 0.18 and 0.21 C/W -- indicating performance considerably below current heatpipe models. But the shape of the cooler has promise for certain types of ducting mods, provided the heatpipes boost performance to contemporary levels.
