Quiet PWM Cooling Fans - PWM Cooling Fans
Quiet PWM Cooling Fans Pulse Width Modulated Technology DC Fans. Acoustic PC Offers A host of the highest quality Quiet PWM fans available on
the market today such as the NOCTUA NF-F12 PWM 120mm Quiet Fan & The Nexus Big Range series Quiet PWM Fans available in 80mm, 92mm,
& 120mm sizes.
What is PWM Technology? High frequency Pulse Width Modulated (PWM) fans perform at low noise levels by eliminating the power switching
noise of the fan. The motor commutation noise is eliminated with high frequency PWM as the coils of the fan are being switched with a frequency
above 20 kHz, which is outside the human audible range. The speed of the fan is controlled by an external PWM signal. PWM Fans can ramp up
linearly from a 20% duty cycle up to the fan's maximum rated speed. Because the fan can run at lower speeds it is more energy efficient and will
therefore have a longer life. PWM Fans are widely used in most Intel's newest motherboards in order to take advantage of the PWM feature you must
plug your PWM Fan in your Intel CPU cooler 4 pin motherboard connector. Also some of our newest fan controllers carry this PWM feature for uses
with this kind of cooling fan.
