I wound up redoing my loop when I got my new motherboard. Among the things that came about as a result was me replacing the gold-plated barbs on the cooler with the "silver" 45 degree fittings I had. This time I also added concentrated antifreeze though.
I also did a new approach to the tubing from my res given the pump's new place... I'm gonna have to redo that when I actually get a GPU in there though, since it currently blocks the PCIe slot.
