Improved cooling performance by new production processors 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. The Alpine 12 LP is able to switch into silent passive mode when PWM signal is below 5 % Due to its new motor. This allows working at your PC in complete silence without any unwanted noise.the new Alpine 12 LP 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 vibrations 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.with an installation height of only 42.2 mm, The Alpine 12 LP is particularly suitable for small and narrow housings. It is easy to assemble and allows full access to all components close to the CPU. The compact top-blower CPU cooler also cools areas around the CPU socket and is predestined for html and Mini-ITX cases.a 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.
