EK Water Blocks expands its EK-Vardar Fan Series with a new 140mm D-RGB version – the EK-Vardar EVO 140ER D-RGB with 9 addressable RGB LEDs. The EK-Vardar EVO 140ER D-RGB features the Extended Range (ER) PWM function along with the Start-Stop function that offers semi-passive cooling and true 0dB silent operation. These features allow builders to fine-tune speeds and performance with full stop option with idling which minimizes dust built-up on radiators, saves power, and prolongs the lifespan of the fan itself.

EK-Vardar EVO 140ER D-RGB

The EK-Vardar RGB is a high-static pressure computer cooling fan, designed and built primarily for radiators of high-performance computer liquid cooling systems. The fan sports a black square frame that does not allow for the air to escape and ensuring optimal airflow through the radiator. The EK-Vardar EVO 140ER D-RGB has an operation range from 400RPM to 1600RPM with a minimum threshold point below 25-30% PWM duty cycle in fan curve settings.

The EK-Vardar EVO 140ER D-RGB sports 7 frosted transparent fan blades for light dispersion. There are 9 addressable RGB LEDs under the motor hub that ensures 360° light diffusion. Each of the ARGB LEDs can be customized offering unlimited illumination effects possible. The fan uses standard 3-pin 5V ARGB connectivity and is supported by all popular RGB sync technologies from major motherboard brands such as the MSI Mystic Light Sync, ASRock Polychrome RGB Sync, ASUS Aura Sync, GIGABYTE RGB Fusion, and others.
