I see the mcp35x pump has pwm capability. Just wondering if the fan head on a 6950 is the same pin out as a CPU fan header. Can I plug the pumps pwm wire into the video card header? Will the video card control the pump speed? Note the pump does not draw power through the pwm wire it has a seperate power connector. Anybody have one of these pumps hooked up to the video card fan header instead of the CPU fan header?
