I won a Corsair h100i gtx on a giveaway and I'm planning out how I'm gonna fit the radiator and where to plug in the cables. I want to have a constant 12 volts to the pump, so I'm not going to use the CPU fan header, but there's a 4-pin fan connector in a great place for cable management. So I was wondering, if I plug that 3-pin pump connector on the 4-pin, will I still get a constant 12 volts?

You can plug it into the CPU fan header and just set a manual fan profile that runs at 100% for any temperature, which I believe would give you a constant 12V. Or set it to any other constant level really, if all you're worried about is fluctuations. Alternatively, I think you can run it right off the PSU (might need a 3 pin molex adapter).

I'm with mcnumpty23 though, this does seem unnecessary. Even if fluctuations are bad for it, it seems to me that running the pump at max 24/7 wouldn't be much better. And if you set a smooth fan profile, the fluctuations should be minor.

Because that's bad for the pump and the fluctuations can ruin it. That's where most of people's "pump noise" issues come from.

That's what I've heard and I don't want to risk it. Can you answer the original question?
