I've got a failing pump in my Koolance PC2 rig, it's got a reservoir with two submerged pumps inside (redundancy is a good thing). Problem is, the old part can't be found anymore. So I'm looking for a replacement. The system is failry low key: 1/4" Tubing 3 x 80mm fan radiator Reservoir and pump gets power from the Koolance control PCB (I'm quite sure it's 12v, but don't know the Amperage - must be around 4 or so) Only cooling my CPU at the moment Eventually, I'd like to upgrade to a 3 or 4 x 120mm radiator and larger tubing. So any suggestions for replacement pump(s) and reservoir that would work with 1/4" now, but can take larger tubing later?
