Pressure requirements seem to be the most confusing thing in the new setup I'm building. First, since I'm going TEC, the components are the polar opposite of restrictive- Swiftech MCW50 on GPU and MCW462 on CPU, most likely MCW20 on NB, and 2-342 heatercores (one for each loop, since the gpu/nb and cpu are going to be two separate loops). If this was for a setup going directly in the PC case, I have no doubts that just about anything would do it... I could just throw in a Hydor and be done with it. However, the fans/radiators are going to be mounted in a box that is about 7-8' away from my pc, with tubes routed on the floor behind my bed. The box setup has a minimum of elbows, and the ones that are there are either just bent tubing (1/2" Clearflex 60- no kinks

) or 1/2" PVC, so they don't terribly restrict flow. Would a single Iwaki MD-15RLT, with a Y splitter on the input and output, be enough to handle both loops?
