At 25%, 50% and 75% duty the fan ran 1011, 12 RPM with quiet clicking. To hear a faint click you must put your ear right up to the fan.Īt both 0% and 100% PWM duty the fan ran the same speed – 1350 rpm, which is weird. A quiet click can be heard a few inches away. The PWM functions of the Arctic F12 PWM were tested, using a grounded PWM wire for 0% PWM duty, and a Zalman PWM Mate to approximate 25%, 50%, 75% and 100% PWM duty. Yate Loon (Model : D14SL-124B) Yate Loon is famous for building inexpensive fans that beat out its higher-price competitors. But considering that this fan is usually sold inexpensively, the wire gauge was clearly a tradeoff that had to be made. The only fly in this ointment is Arctic’s use of fine wires throughout. And if you don’t have another fan (it need not be PWM), the fan has its own RPM line to report its speed to the motherboard. Not only does the setup pass the PWM signal through to the next fan, but it also politely passes the next fan’s RPM signal back through to the motherboard. Such mechanism ensures silent operation when it is idle, but also gives sufficient performance when the demand comes. We test a total of 60 fans in 71 variations- 120mm and 140mm. The patented PST (PWM Sharing Technology) forwards the PWM signal to all other fans within the system so that all fans are spinning at the same speed. After looking at pictures of the Yate Loon, the fan blades look almost. 2500 does seem a little high for 40 CFM, should probably be closer to 1500 or so. both Yate Loon and Young Lin are companies in Taiwan that 'have factories. Yet, it measures at 47 CFM airflow level and is available at a reasonable price. Via a single PWM signal, the CPU fan is controlled by the mainboard to maintain the ideal temperature of the CPU. The description says '120Mm Ultra Quiet Ball Bearing Case Fan' The specs say: Fan Type. This 120mm case fan is extremely quiet case fan.
