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.
Other key characteristics of EK-Vardar EVO fans are:
- igh-static pressure / low noise profile – unlike other general-purpose computer cooling fans, the EK-Vardar EVO family of fans is built specifically for computer liquid cooling systems, namely radiator cooling. The 7 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 are also very suitable for high-performance air coolers or as case fans for restrictive cases with dust filters.
- High-quality motor and bearing assembly – New electrical design, actively cooled motor windings and Hydro-Dynamic bearing (only with ER models) with 50.000 hours life span (MTBF) ensures uninterrupted operation for years to come. Precise Pulse Width Modulation (PWM) for fan speed adjustment allows performance on demand.
- Sealed-edge fan casing – The classic, yet effective square shape of the fan casing provides optimal performance in either pull- (suction) or push (pressure) regime without hydraulic losses thus ensuring the optimal cooling capacity of your liquid cooling radiators. The classic shape of the fan frame also allows easy cable routing while grouping more fans on one radiator.
- Timeless design – the EK-Vardar EVO fan fits subtly into any liquid cooling computer without drawing too much attention. Fans are available in a single (all black or all white) and two-tone (black with gray blades) color variations.
