Alphacool Apex Stealth Metal Fan 2000rpm Gold - 120mm 13854

High-quality, elegant as well as timeless design and technical innovation - these are the features of the Alphacool Apex Stealth metal fan. With its patent-pending decoupling technology, the robust metal frame and a special rotor, this fan certainly impresses. Not only is the Apex Stealth one of the most powerful fans, but it also remains the quietest at any speed. Whisper Quiet The fan blades, motor and its suspension are completely decoupled from the metal frame. For this purpose, a special damping system was placed between the metal frame and the fan, which absorbs all vibrations. This type of decoupling is a completely new system, which is brought to the market by Alphacool for the first time with the Apex fan. In addition, the impeller is equipped with a closed frame that prevents the impeller tips from fluttering at high speed, which also has a positive effect on the fan's characteristics. Powerful All-rounder The Alphacool Apex Stealth metal fan is a true all-rounder. It sets new standards in terms of airflow and static pressure. Therefore, this fan is not only perfect for mounting on radiators, but also provides excellent airflow as a case fan. The Apex Stealth can be controlled between 400 to 2000 rpm via the 4-pin PWM connector. The startup speed is ~420 rpm. In addition, the Stealth offers Zero RPM control, which can be used to bring the fan to a complete stop. Apex Design Alphacool's Apex product line represents the highest level of perfection. First-class materials and innovative technologies guarantee a unique premium product. Consisting of high-quality metal, the curved frame gives the Apex Stealth its distinctive design and fits perfectly into any PC build. Additional Features As usual with Alphacool, multiple fans can be effortlessly connected in series via daisy chain. The cables can be hidden in the corners of the fan so that they are no longer visible. A 50 cm PWM cable is also included as an extension. The 6-pole motor in combination with the HDB bearing (Hydro Dynamic Bearing) ensures extremely quiet operation and high durability.
