I don't think you should run pumps on PWM. No idéa why but someone told me not to on some forum.

I didn't even know there where an 18W version? I got mine from alphacool and they don't mention how many watts the pump use. So I read over at vcore.dk that the Ultra version uses 10W. My DDCs are the 1Plus version /w plexi top called DDC-Ultra so they are probably the 18W ones? I thought thought they used a bit too much power but I assumed it was because I ran them on 13.5V at the moment.

The miniNGs got over 100W peak in analogue mode, the only reason you can't use all that power 24/7 is because of the cooling. Hence if you cool it better you can use more power. It's got some kind of safety function so that if you overload it in analogue mode it switches to PWM mode. I've run my two DDC-Ultras from the miniNG in analogue mode at 12V for a few hours w/o any problems. I had a fan blowing directly at it. My rig isn't very organized yet so I run them of my external PSU untill my chassi is done. I guess I should look for some better cooling for the miniNG.
