be quiet! Silent Wings Pro 4 140mm PWM 6-Pole Fan Motor Technology 4-pin PWM PC Fan BL099
Introducing the be quiet! Silent Wings Pro 4 140mm PWM PC Fan, designed for users who demand advanced cooling solutions for their PCs. This high-performance fan combines efficient airflow with a quiet operation, making it an ideal choice for both gaming rigs and workstations. Coming with a 6-pole fan motor technology, it ensures optimal performance and durability, catering to PC builders and enthusiasts alike who seek to maintain a cool system without intrusive noise levels. What Makes It Different? The Silent Wings Pro 4 distinguishes itself from other cooling solutions through its precision-engineered design aimed at reducing noise while maximising airflow. While other fans might focus solely on airflow, this model strikes a fine balance, offering unmatched quiet performance due to its innovative motor and blades. It's specifically positioned to meet the needs of users looking for a silent yet powerful fan solution, unlike basic or budget models which often sacrifice one for the other. Additionally, this fan comes equipped with a 4-pin PWM connector enabling speed control based on the PC's needs, which is not always found in more standard fans. This feature allows for energy efficiency and enhances the longevity of your components, appealing particularly to those who keep their systems running for extended periods. Performance & Everyday Use This fan operates at a size of 140 mm, providing ample airflow without compromising space within the chassis. Featuring a weight of just 258g, it remains manageable during installation while ensuring sturdy performance. The PWM functionality allows it to adjust its speed dynamically, reducing noise during light tasks while accelerating during heavy loads, making it versatile for everyday use be it gaming, streaming, or regular office tasks. The construction and materials used in the Silent Wings Pro 4 are intended to minimise vibrations, further contributing to its quiet operation, especially critical in audio-sensitive environments like studios or living rooms. With a five-year warranty backing its reliability, users can rest assured of its durability, making it a long-term investment for PC enthusiasts looking for quality. Compatibility is another strength for this fan, as it is designed to fit universally across most PC cases and configurations. This means it can be seamlessly integrated into any setup, whether you're upgrading an existing system or building a new one from scratch. Why Choose This be quiet! Silent Wings Pro 4 140mm PWM Fan? Choosing the Silent Wings Pro 4 means investing in superior cooling technology without the compromise of noise levels. Outstanding acoustic performance for a quiet computing experience, ideal for sensitive tasks. PWM functionality allows tailored cooling solutions based on system demands, enhancing both efficiency and longevity. High-quality build and design ensure reliability, backed by a five-year warranty. Universal compatibility makes it easy to incorporate into any system with minimal hassle. However, users who require cutting-edge performance in extreme gaming or heavy computational tasks may want to explore more advanced or specialised fan solutions. If you prioritise absolute peak performance in cooling over noise levels, consider higher-tier cooling systems. Users aiming for overclocking configurations may benefit from fans designed specifically for high airflow. Those with larger cases may require multiple cooling solutions or larger fans for optimal heat dissipation. Great For The be quiet! Silent Wings Pro 4 is ideally suited for users who seek silent operation without sacrificing performance, appealing particularly to gamers, content creators, or office workers. Its emphasis on acoustic comfort makes it valuable in environments where noise control is a priority. Everyday office tasks or light computing. Building or upgrading gaming rigs focused on noise minimisation. Streaming or content creation where audio clarity is critical. Genera

be quiet! Silent Wings Pro 4 140mm PWM PC Case Fan, Optimized Fan Blades, Extraordinary High Performance, Speed Switch for Changing Maximum PWM Speed, 6-Pole Fan Motor, Fluid-Dynamic Bearing BL099
The fan blades are what makes a fan. It is for this reason that the fan blades of Silent Wings Pro 4 140mm PWM have been developed newly from scratch. The new blade arrangement enables a performance second to none for all possible operations. Be it in a case, on radiators or heat sinks. Silent Wings Pro 4 140mm PWM makes for extraordinary air pressure and therefore, significantly increases the system’s performance. The decreased distance between the fan blades and the frame enables an extraordinarily high air pressure. By that, the Silent Wings Pro 4 140mm PWM allows the user to run even the most demanding applications. The speed switch makes switching between medium, high-speed and ultra-high-speed of maximum RPM levels quick and easy. The Silent Wings Pro 4 140mm PWM alters its application with a simple slide to the right. Medium-speed is suitable for any operation that requires regular cooling performance. High-speed lets the fan spin faster, providing more cooling power. Ultra-high-speed ultimately offers enough rpm to cool even the most demanding hardware in high-end PC builds. 6-pole fan motor with 3 phases for very low power consumption, less vibration and therefore quiet max. operation of 36.8dB(A). Equipped with this state-of-the-art technology the fan is virtually inaudible when operated in mid-speed. Silent Wings Pro 4 140mm PWM has 3 mounting options in the scope of delivery. The pre-installed radiator corners are specially designed for radiators on which the incomparable performance of this high-end fan completely shines. On the other hand, for chassis use, the anti-vibration mounting is the first choice as they reduce vibrations to a minimum. The plastic mountings round up the scope.
