Ideally what I'd like to do is pull the PWM control from the fan header on the GPU, and put that into some kind of controller to adjust the speed of ... has a DC variable resistor rather than ...

An enterprising individual has shared a quick step-by-step guide showing how to convert an old Hard Disk Drive (HDD) into a small but useful variable ... Amp Electronic Speed Controller (ESC ...

It provides continuously variable motor speed in response to 0-10 VDC or 4-20 maDC input signals. A free, four-page data sheet on the controller is available.
