Has anyone tried one of these pmw fan adapters to see if it works, or does the sp20 have a different wiring solution? http://www.amazon.com/GELID-Graphics-Cooling-Connector-Conversion/dp/B005ZKZEQA I was thinking about using a delta I had lying around and seeing what difference it makes for noise, but I would like to keep the wiring clean.
I'd be interested in knowing if this adapter worked as well. Have a few 4 pin PWM fans I would like to try to experiment with in the SP20's.
