Arctic Alpine 23 Low Profile AMD CPU Cooler – ACALP00035A Improved Cooling PerformanceThe high thermal conductivity of aluminum is fully retained in a new type of extrusion. This new production process makes it possible to manufacture a powerful and at the same time very compact radial heat sink. The particularly fine cooling fins of the new Alpine are fanned out in a Y-shape. This increases the surface area of ??the heat sink and increases the cooling capacity.Wide Speed RangeThanks to its new motor, the Alpine 23 has a very wide, PWM-controlled speed range. This reduces noise to a minimum and at the same time guarantees maximum cooling performance.Lower Power Consumption & VibrationThe new Alpine 23 is powered by a revised engine, which makes it more efficient. Thanks to sinus magnetisation, the motor generates only 5% of the commutation oscillations of a conventional DC motor. Without compromising on performance, these factors save energy, lower the motor coil temperature and reduce vibrations to a minimum.High-Quality Plain BearingThanks to a combination of alloy / lubricant developed in Germany, the friction within the bearing is reduced and greater efficiency is achieved. This way, less heat is generated, there is less bearing noise and the life of the fan is extended.Improve Service LifeA 10 ? C lower motor temperature roughly doubles the service life. Due to the low coil temperature of the new ARCTIC fan motors, the service life of the fans is around four times as long.MX-2 Thermal CompoundThe already pre-applied, very high-performance MX-2 thermal compound ensures quick and clean installation.Simple and Tool Free AssemblyInstallation is child’s play thanks to the mounting clips. The Alpine 23 is simply plugged onto the existing AMD retention modules and screwed tight.
