I'm building a PC with a Silent Loop 280 to cool my CPU. Since the Silent Loop 280 uses standard fittings and can be disassembled/rebuilt I'm considering in the future possibly adding an additional radiator, a reservoir, and a GPU block into the loop. If I simply unplugged the pump on the waterblock would it be safe to put something like a D5 pump in to run the loop? I'm concerned that the built in pump wouldn't generate enough pressure to run a larger loop, but I'm worried about whether the existing pump can handle having another more powerful pump forcing liquid through it. I know it's a bad idea to run two pumps in series at different rates, but is it still harmful if the pump isn't running?
