The EK-Vardar EVO 120ER RGB is a high-static pressure computer cooling fan, designed and built primarily for highest-performance computer liquid cooling systems. Developed in-house and first introduced in 2014, the EK-Vardar fan is now also available as EK-Vardar EVO 120ER RGB. Beside the RGB lighting effect, the new fan also packs the Extended Range (ER) of PWM operation feature and the special Start-Stop function which brings a true 0dB experience for the absolute silent fan operation. EK-Vardar EVO 120ER RGB is simply the best choice of RGB fan for computer radiator cooling as it provides unmatched performance throughout the entire operating range. The perfectly balanced milky colored 7 fan blade design is optimized for light dispersion and high-pressure operation while maintaining the low noise profile throughout the whole operation range of the fan. Under the motor hub, there are total 9 LEDs making this the brightest RGB fan on the market, ensuring perfect light diffusion at broad daylight as well. One of the key features of the EK-Vardar RGB fans is its simplicity as it uses standard 4-pin 12V RGB connectivity. Meaning it can be used with any standard 4-pin 12V RGB controller or any of popular RGB sync technologies from all major motherboard manufacturers. The arrow marking on the 4-pin LED connector is to be aligned with the +12V marking on the RGB header. The Vardar family of cooling fans carries the notorious name of a type of the cold northwesterly wind blowing from the mountains down to the valleys of Macedonia. It is a type of ravine wind, enhanced by a channeling effect while blowing down through the Moravia-Vardar gap, bringing cold conditions from the north to the Thessaloniki area of Greece. Most frequent during winter, it is blowing in the rear of a depression when atmospheric pressure over eastern Europe is higher than over the Aegean Sea.
