EK Water Blocks has launched a new range of EK-Vardar fans featuring start-stop functionality. These extended range PWM fans are being made available in 120mm and 140mm sizes, in various colours and with various maximum RPM speeds. The new EK-Vardar EVO fans with start-stop functionality can help bring a "true 0dB experience" to your PC usage. EK says that as well as the benefit of a quieter environment the start-stop feature prevents dust build-up in idling PCs and extends fan lifespans. Please note that not all the new EK-Vardar EVO fans feature 0dB tech, only the ones with the 'ER' suffix.
In a press release sent to HEXUS, EK explained how its new EK-Vardar EVO (ER) fans decide when to stop spinning: "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."
