EK Water Blocks is releasing a new lineup of its renowned EK-Vardar fans. Developed in-house and first introduced in 2014, EK-Vardar fans have now evolved into new EK-Vardar EVO lineup.
EK-Vardar EVO fans with Extended range (ER) of PWM operation feature a special Start-Stop function which brings a true 0dB experience for the absolute silent fan operation. The electronics of the new ER EVO fan has been specially tweaked so that the fan stops spinning if the PWM signal falls below a certain duty cycle value. Not only will you be able to enjoy a totally silent PC, but this feature is also very useful for preventing radiator dust buildup in idling PCs and prolongs the lifecycle of the fan itself.
EK-Vardar EVO is industrial grade high-static pressure computer cooling fan, designed and built primarily for highest-performance computer liquid cooling systems. The Vardar EVO 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.

Hydro-Dynamic Bearing and Start-Stop Function for Complete Silence!
The unique Start-Stop function featured with the EK-Vardar EVO ER models will ensure the user a true 0dB noise environment. If the PWM curve is set so that the PWM duty cycle is below 25-30% PWM (depending on motherboard model) the fan will simply stop spinning. If the PWM duty cycle is raised by the fan control software, the fan will spin up once again. EK-Vardar EVO ER models also feature Hydro-Dynamic bearing which is superior to double-ball bearing due to less friction, wear and vibration and consequently less noise.
