Hey folks, so my Alphacool AP1510 pump recently started to leak due to a hairline fracture on the output. As such I am looking at a replacement pump, the pump I have been looking at is the MCP355 Laing DDC-pump 12V DDC-1Plus 18w. Will this pump be a suitable replacement for the AP1510 considering that the mcp355 has only a 4.7m head and 600l/h flow, compared to the 6m head and 1500l/h for the ap1510? I beleive the ap1510 is a bit of a beast of a pump, and perhaps is/has been overkill for my rig? I am using a fairly simple loop consisting of... res > pump > cpu > rad120 > gpu > rad240 > res res = Alphacool Repack-cooling slot Black Reserves and Compensating Reservoir cpu = EK-Supreme HF Full Copper Universal CPU Block AMD,Intel gpu = EK FC5870 5870 CF, Plexi, Full Cover Block The radiators are a bit old and I have no idea what make or model they are. As I tend to overclock my pc, am I likely to experience toomuch of a cooling performance drop if I used the MCP355? I am a little worried that being used to a beast of a pump that I may need to tweak down my overclock to match the temps I was getting previously. Please let me know your thoughts gents, your comments as always are appreciated. Cheers, Delph.
