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