"Zalman's CNPS10X Optima heatsink is a fairly standard tower cooler in most respects; it offers pretty good thermal performance, accomodates a front and rear fan and has an exposed copper heatpipe base. The CNPS10X Optima CPU cooler stands 153mm tall so it should fit into most mid tower chassis and weighs in at moderate 630 grams. The CNPS10X Optima's raw aluminum fins are punctuated by the four copper heatpipes which intersect the fins in the region receiving the highest airflow from the fan. Like many tower heatsinks, Zalman have conspicuously staggered the heatpipes where they intersect the cooling fins to ensure heat conduction is over a broader area of fin."
