EK-Furious Vardar EVO 140 BB (2500 RPM)
The Vardar family of cooling fans carries the name of a type of the cold north-westerly wind blowing from the mountains down to the valleys of Macedonia. It is a type of ravine wind, enhanced by a channelling 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.

The key characteristics of EK-Vardar fans 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 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 double-ball bearing 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. Delivered in all black colour scheme it blends perfectly with a sleek and minimalist looking EK-Cool Stream liquid cooling radiator.
