Arctic Alpine 23 CO Compact AMD CPU Cooler for Continuous Operation | Features: | 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. | Wide rpm Range | The Alpine 23 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 Vibration | The new Alpine 23 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 the vibration from the commutation of a regular DC motor. These factors contribute to saving energy, lowering the coil temperature, and reducing vibrations to a minimum without compromising performance. | For Continuous Operation | The premium quality 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. | Pre-Applied MX-4 Thermal Paste | The pre-applied, high-performance MX-4 thermal compound ensures fast and clean installation. | Easy and Fast Installation | Thanks to the mounting clips, the installation is really easy. Alpine 23 CO is simply plugged into the existing AMD retention modules and screwed tight. | General Specifications | Compatibility | AMD Socket: AM5, AM4 | Ram Clearance: unlimited | Warranty: 6 Years | Operating Ambient Temperature: 0-40 °C | Heatsink | Outer Diameter: 93.4 mm | Fin Material: Aluminum | Number of Fins: 50 Y-shaped Fins | Thermal Paste: MX-4 pre-applied | Fan | Fan Diameter: 90 mm | Fan Speed: 200 - 2700 rpm | Fan Bearing: Dual Ball Bearing | Noise Level: 0.3 Sone | Current: 0.09 A | Connector: 4-Pin | Size & Weight | Installation height: 65 mm | Length: 98.6 mm | Width: 121 mm | Height: 65 mm | Weight: 275.5
