Top-Notch Price-Performance RatioThanks to its radial heat sink and good fan design, the Alpine 12 CO offers a lot of performance at a very low price point. In internal tests leveled to 28 dB(A), the cooling performance of the Alpine 12 CO exceeded the competition, in some cases by more than 10°C.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 12 CO 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 12 CO 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.For Continuous OperationThe premium quality Japanese dual ball bearing allows continuous operation 24/7 without the slightest compromise in performance. Dust and high temperature are affecting this bearing a lot less than generic sleeve or one ball bearings and thus make it the perfect choice when reliability is essential.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 push pins, the installation is really easy. Additional tools are not needed to install the cooler.
