Also, could I add the northbridge into that loop by any chance? I know I don't need to but I would like to so if I can I would do it.
Forgot to address this.
Yes, you can, you simply need to determine which block fits your NB on your motherboard. The amount of heat put out isn't huge, so you can fit it into your current loop config without really needing to make any real adjustments for more rad space.
