The EK-Vardar S 120ER D-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 S 120ER D-RGB. Besides the addressable D-RGB lighting effect, the new fan also packs the Extended Range (ER) of the PWM operation feature and the special Start-Stop function which brings a true 0dB experience for the absolute silent fan operation. EK-Vardar S 120ER D-RGB is simply the best choice of addressable 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 is a total of 9 LEDs making this one of the brightest D-RGB fans on the market, ensuring perfect light diffusion at broad daylight as well.

One of the key features of the EK-Vardar D-RGB fans is its simplicity as it uses standard 3-pin 5V D-RGB connectivity. Meaning it can be used with any standard 3-pin 5V addressable D-RGB controller or any of popular RGB sync technologies from all major motherboard manufacturers. The arrow marking on the 3-pin LED connector is to be aligned with the +5V marking on the D-RGB (ARGB) 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. 

Other key characteristics of the EK-Vardar S 140ER D-RGB fan are:

• High-static pressure / low noise profile - unlike other general-purpose computer cooling fans, the EK-Vardar family of fans is built specifically for computer liquid cooling systems, namely radiator cooling. The 7-fin fan blade design is optimized for high pressure operation while maintaining the low noise profile throughout the whole operation range of the fan. Vardar's design and construction is also very suitable for high-performance heat-pipe air coolers.
  
• High-quality motor and bearing assembly - Proven electrical design, actively cooled motor windings and Double Ball bearing with 50.000 hours lifespan (MTBF) ensures uninterrupted operation for years to come. Phase-width modulation (PWM) fan speed allows performance on demand.
• Sealed-edge fan casing - The classic, yet effective square shape of the fan casing ensures optimal performance in either pull- (suction) or push (pressure) regime without hydraulic losses thus ensuring optimal cooling capacity of your liquid cooling radiators.

• Timeless design - the EK-Vardar fan fits subtly into any liquid cooling computer without drawing too much attention. Single- and two-tone colour design with monochrome fan sticker. Less is more.
• 0db regime - EK-Vardar features a unique Start-Stop function which ensures the user a true 0db noise environment. When the fan curve is set with the minimum threshold point below 25-30% PWM duty cycle (depending on the motherboard model), the motor and the electronics will turn off and the fan will simply stop spinning. EK-Vardar EVO restarts operation automatically as fan control ramps up its operational duty cycle past threshold start-stop point. This feature is very useful for preventing radiator dust buildup in idling PCs and to prolong the lifecycle of the fan itself.

• Slim black cables - The Vardar RGB fan features simple slim black cables with no additional cable sleeving. This will enable easier cable routing and much less cable clutter.
