I have a dtek version csp 750 pump(which apparently sucks now) that has been running for about 6 months now and is still fine. It is cooling my mobile axp with a dtek pro120 heatercore. I want to w/c my new 6600gt also, and i dont know if i should get a new pump like an aquaextreme/swiftech 600 series, or get another dtek csp750 and run either 2 seperate loops or use them in parallel or series. Also, would the single 120 heatercore be enough to cool my cpu and gpu or should i get a newer dual 120 bonneville rad or something similar? THanks for the input.
