Help to choose a pump

I'm pretty sensitive to my computer noise. I have to slow down my pump to ~ 2000 rpm (full speed is 4500)before I can tolerate the noise. I also run my fans @ 5V or lower if possible.

CTR-SPD24X2 Dual 24V Pump Controller

They also make them for one pump.

interesting. i am already not sure that my 1 655-b pump is going to be enough for the system i am building, i was going to add a mcp 350 pump that i have also in the loop somewhere. would bumping up the voltage on the 655 be a better idea for a cleaner install and still push through everything in the loop?

Don't mix and match pumps. Stick to one type. Either way you'll be fine. Flow rate is hugely overrated. You also can't bump the voltage past 12V on a D5 unless you have the D5 strong model.

Cool, thanks for the info.
