PWM Cooling Fans

PWM Cooling Fans

Quiet PWM Cooling Fans Pulse Width Modulated DC Fans. Acoustic PC Offers the highest quality quiet PWM fans available on the market today
such as the Scythe Kama Series PWM fan & the Arctic Cooling AF Series ULTRA quiet PWM fans. Available in 80mm, 92mm, & 120mm sizes.

Acoustic PC offers a host of high frequency Pulse Width Modulated (PWM) fans that 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. The Scythe KAMA and The Rexflow Quiet 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 widley used in most intel's newest motherboardsin oreder to take adavantage 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.
