Nexus AXP-3200 The Nexus AXP-3200 SkiveTek® is an aluminum & copper, SkiveTek® technology heat sink equipped with a fan with 2400 RPM and a noise production of only 19 dB(A). The aluminum heat sink has a 99.5% pure copper base plate fitted over the full bottom of the SkiveTek aluminum heat sink for optimal heat conductivity. The patented V-shaped fins on the Nexus AXP-3200 SkiveTek® optimize the airflow and prevent air obstruction. This results in a stable RPM level and an extremely low noise operation. Retail Packaging Heat sink without fan: What is the SkiveTek®? SkiveTek® is one of the worlds most advanced technologies. This concept permits the production of heat sinks with a precise and super fine detail previously considered impossible. SkiveTek® represents a process of shaping materials to produce high fin density thermal solutions. Base plate and fins are constructed out of one piece of pure aluminum or copper by cutting the material in thin layers, bending the fins in place. No bonding, welding, soldering or adhesive is involved; the joint between fin and base is continuous aluminum or copper. SkiveTek®- ultimate heat conductivity!
