Compact AMD CPU-Cooler Improved Cooling Performance By New Production ProcessThe high thermal conductivity of aluminum is fully retained by a new type of extrusion. This new production process creates a powerful yet very compact radial heat sink. The particularly thin cooling fins of the new Alpine are fanned out in a Y-shape. This increases the surface area of the heat sink and therefore the cooling capacity. Wide RPM RangeThe Alpine 23 features a new motor technology with a very wide, PWM-controlled RPM range. This keeps the noise level at a minimum while guaranteeing maximum cooling performance when needed. Lower Power Consumption & Minimum VibrationThe new Alpine 23 is powered by an updated motor and runs much more efficiently than its predecessors. Due to sinus-magnetizing the new motor creates just 5 % of the vibration from commutation of a regular DC-motor. These factors contribute towards saving energy, lowering the coil temperature and reducing vibrations to a minimum without compromising performance. High Quality BearingThanks to an alloy/lubricant combination developed in Germany, friction within the bearing is reduced and greater efficiency is achieved. As a result, there is less heat development as well as less bearing noise, which means you can enjoy a longer service life from your fan. Extended Life SpanA 10 °C lower motor temperature roughly doubles the life span of a fan. The new ARCTIC motor has a four times longer service life through its low coil temperature. Pre-Applied MX-2 Thermal PasteThe pre-applied, high-performance MX-2 thermal compound ensures fast and clean installation. Easy And Tool-Free InstallationThanks to the mounting clips, the installation is really easy. Alpine 23 is simply plugged onto the existing AMD retention modules and screwed tight.
