The Nanoxia 3-Pin to 4-Pin PWM
fan controller is a unique adapter that allows you to plug any standard 3-Pin
fan into your PWM motherboard and have your motherboard control your standard
fan as if it were a PWM fan! The Nanoxia PWMX does this by the Nanoxia
controller chip that detects the connected fan and generates the fitting PWM
characteristic; enabling every 3-Pin 5-12V fan to be accessed by PWM enabled
motherboards. The Nanoxia PWMX also has a manual rheostat onboard so you can
even further fine tune your fans speed.
