OK, finally got my first loop up and running...waiting on second pump + male QDC's for my main rig, this is my test rig, haha. Cost was less then $200, and I was able to cool the CPU + NB.
I have a NB heatsink that someone fabed themselves, which is working really slick, but kind of brutal mounting.
Otherwise, my temps are definitely lower on full load, so I am happy with that.
40C on full load, which used to be well into the 55-60 range. Now my MB temp is always below 40C, which used to be around 60 (very hot NB on this p5n-d board).
