Top-Notch Price-Performance Ratio

Thanks 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, 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 Process

The 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.

0 dB Mode

The Alpine 12 CO 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.

Lower Power Consumption & Minimum Vibration

The 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 Operation

The 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 Span

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.
