Founded in 1980 and headquartered in Taiwan, Sunon (aka Sunonwealth Electric Machine Industry Co., Ltd.), stands out as a outstanding world producer of followers, blowers, and thermal administration techniques. The firm has made a reputation for itself within the fan business with a complete product line that features DC brushless followers, micro blowers, CPU coolers, and numerous different cooling applied sciences. They are one of many oldest and most famed fan producers on the world – and never only for PC functions, however for absolutely anything in want of one thing smaller than a ceiling fan, spanning from IT to automotive and industrial sectors.
Within the PC house, the corporate is finest recognized for its proprietary MagLev (Magnetic Levitation) know-how, which makes use of magnetic forces to levitate the rotor shaft, drastically decreasing friction and put on. This revolutionary design improves the sturdiness and efficiency of their followers, significantly in decreasing operational noise and bettering high-temperature efficiency. Sunon launched the patent and their first MagLev merchandise all the best way again in 90s.
The 120mm Sunon MagLev fan that we’re reviewing at this time – MFC0251V2-1Q02U-S99 – is a brand new, high-performance fan engineered primarily for PC functions, with an emphasis on longevity and performance. It options Sunon’s superior Vapo-Bearing MagLev Engine, which allegedly ensures a quieter operation and longer lifespan by minimizing friction. This explicit fan has a most velocity of 1900 RPM and the entire bells and whistles of superior cooling followers, together with a variety PWM velocity management (10-100%).
Distinguished by its crisp white coloration and distinctive body design, this fan is aimed PC builders going for a clear and fashionable aesthetic. The “gaming” designation by the producer clearly divulges their intentions relating to their focused viewers. By default, these followers have each a 4-pin connector and in addition a Molex connector for his or her direct connection to the PSU.
Fan Testing Methodology
We are testing followers utilizing an Extech HD350 differential manometer, an Extech AN200 velocity meter, and a customized 3D printed equipment designed for this particular objective. The equipment includes a easy however efficient shutters mechanism that enables us to check the unobstructed (most) quantity move of a fan, the totally obstructed (most static) strain of the fan, and a number of factors in between, permitting us to compose the precise P-Q efficiency chart of any fan. The RPM studying is taken with the fan unobstructed (most move), because the fan velocity varies relying on the airflow impedance along side the design of the fan’s blades.
For noise measurements, we’re utilizing an Extech HD600 excessive sensitivity SPL meter. The noise of the fan is measured from 15 centimeters away, not one meter as IEC certifications require, as that will be far too nice a distance to measure variations between practically silent merchandise. Note nonetheless that we’re measuring the noise degree of a fan with its move unobstructed and the fan, to the absolute best diploma, uncoupled from the setting. The addition of fan grills, the set up on a cooler, and some other type of obstruction will improve the generated noise, as each aerodynamic and vibration noise will probably be added into the setting.
Test Results & Conclusion
The Sunon MFC0251V2-1Q02U-S99 is a strong performer throughout the whole thing of the efficiency chart. At its most velocity of 1900 RPM, it affords an airflow of 58.9 CFM and a static strain of two.48 mmH2O. However, that efficiency comes with a noise output of 41.three dB(A), which is kind of noticeable and, usually, probably not forward of its competitors. When in comparison with the Corsair ML120, one other fan with a magnetic levitation engine, the Sunon mannequin…
