Nexus AXM-8200 Quiet CPU Cooler The Nexus AXM-8200 is a tremendously quiet CPU cooler for AM2, 940, 939, 754 socket CPU's. This tower (side blower) CPU cooler is equipped with two high performance copper heat pipes with an diameter of a 8mm. The cooler has a combination of pure copper aluminum fins for the best possible dissipation/weight balance. The PWM-controlled fan has 10cm diameter rotor to provide massive airflow all directed directly at the heat-pipes. The RPM has been set to a maximum of quiet 1500 RPM speed, yet with enough CFM and static pressure to give your CPU all the necessary cooling it requires.     The PWM-controlled fan has a fan speed range of between 700~1500 RPM with a corresponding noise level of just 17 ~ 25.5 dB(A). The high performance characteristics of this cooler guarantees the lowest possible fan speed (and therefore the quietest possible operation) for your computer system.       The two U-shaped copper Heat-Pipes with which the AXM-8200 is equipped have a massive 8mm diameter. This in contrast with many coolers in the market with only 6mm diameter heat pipes. This 2mm extra gives the cooler the extra power to cool the CPU without massive airflow.       The AXM-8200 has a PWM controlled fan with a speed range of between 700~1500 RPM. The cooler size is: 11 x 7.2 x 14 cm / 4.3 x 2.8 x 5.5inch (including fan) The PWM-controlled fan has a rotor of 10cm diameter. The fan mounting is traditional 92mm form factor. The 2 copper U-shaped Heat-Pipes are embedded in a copper base.   Cooler Specifications Dimensions: 11 x 7,2 x 14 cm/4.3 x 2.8 x 5.5 inch (including fan) Fins: 19 pure copper fins, 40 pure aluminum fins Heat Pipe: 2 copper heat pipes with a diameter of 8mm/0.3 inch Base Material: Copper Fan Specifications Propeller diameter: 10 cm/3.9 inch Mounting: 92mm case fan standard Speed: PWM controlled, Max. 1500RPM ±10% Noise level: 17dB(A) ~ 25.5dB(A) Bearing: EL bearing Rated voltage: 12V Rated current: 0.18A Power consumption: 2.16W Warranty: 3 years   The AXM-8200 is very easy to assemble because of its straight forward lever. The fan is mounted with a metal clip and the metal clip has a silicon rubber coating where it is in contact with the fins, this is done to prevent any resonance between the fan and the fins. Without any modification the cooler can be used for Socket AM2, 940, 939 and 754 straight from the box.   The AXM-8200 comes with the mounting leaver pre-assembled. So no further assembly is necessary. Also included in the box is a high performance silver thermal paste. Just put a thin film of the silver paste on the CPU core and mount the AXM-8200 CPU cooler.   The combination of aluminum and copper fins give a great balance between heat dissipation capabilities and weight. High fins density for the largest possible surface area.   The fan is mounted with a metal clip and the metal clip has a silicon rubber coating where it is in contact with the fins, this is done to prevent any resonance between the clip and the fins.
