4-Wire Voltage Controlled PWM InnovationJMC has developed a new design to eliminate the cost of a PWM controller on driving motherboards or fan control circuitry. This is especially useful if you use more than four PWM fans in your chassis because you will eliminate the cost of multiple PWM fan controllers on your motherboard. The method is explained in the attached presentation that you can
view by clicking on the button to the right. JMC sets the PWM frequency
internal to the fan at

40mm PWM Fan JMC has now miniaturized the PWM control logic
to fit into a 40mm DC fan. In order to achieve PWM fan speed control
of a 1U application almost any duty cycle to RPM curve can be customized
as needed.

Attached is an Intel presentation from Nicholas Weber presented at the past Intel Technical Symposium (ITS) that explains the new efficiencies Intel has planned for eliminating excess air flow to reduce noise. If you have any questions about this presentation please reply to this article and a JMC engineering can further explain this future fan speed control concept.
