EKWB EK-Vardar EVO 140ER Black BB

EK-Vardar EVO is industrial grade 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, renowned 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. EK-Vardar EVO is simply the best choice for computer radiator cooling as it provides unmatched performance throughout the entire operating range.

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 the Dual-Ball bearing with 50.000 hours of lifespan (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 the 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.
