I have looked and can't find a definitive answer. I have lurked these boards for over two years and just realized I never registered :P I recently switched from straight water to chilled. Approx -27C . My temps were nowhere near what I was expecting. 14c according to MBM at idle. I had an old maze2 block. This is on a xp2400-m currently @10x220/ Abit NF7 btw. I upgraded to the rbx with brass top and now my pump flow is weak. I tried the #1 and #5 nozzles so far, my temps are better at 8c . I had two pumps laying around and tried them separately and in series. Eheim 1048 and mag2. Obviously not enough flow as it seems the rbx shines above 2 gpm. Question is what will pump 2+ gpm and withstand the temps ? The mcp-650 isn't rated that low. I had to epoxy both my pumps because the inlet cracked from the temps. :shrug: I don't want to spend a fortune , but I don't want to drop 75+ on a pump and have it crack either. Any suggestions ?
