I am pretty sure [NAME]-Ole made an adapter to convert from the Dell/AW version of Asetek cooler to a more readily available Corsair (Asetek) Liquid-Cooler. IIRC, he also posted pinouts here to build your own.  Another option is to buy a new or "working pull" of DPN 01YGW .
I need to replace the water cooler in my ALX but the plug from the pump is a proprietary 7 pin (only using 4) that connects to the top of the computer by the motorized louvers. Problem is any aftermarket cooler is a 3 or 4 pin. How can I rewire this to make it work? I have the tools and knowledge to do this but I just don't know which wire goes to which pin, all the wires are black. Any help would be appreciated.
