RPM speed curve including water cooling pump?
there is a method to manage the speed curve of a water cooling pump. you have the Swiftech MCP655-PWM-DRIVE, and you want the pump to completely stop when the CPU temperature drops below 50 degrees. msi afterburner can achieve similar results with GTX980 fans, so you're aiming for a completely silent PC during non-gaming times.

This isn't the first time someone said that, but I tried two different pumps and both were quite noisy. Even when the pump was placed on soundproof material, I could still hear it clearly. It's not an extremely loud sound, but definitely not very quiet—much louder than fans.
It seems my i7-4790k can handle passive cooling without a fan, so I wondered if it might work similarly with a massive 3x120 WC radiator dedicated to the CPU in a closed loop.
There isn't a reason why you would want the pump to stop. Likewise, there really isn't a reason to throttle a pump up and down all the time, either. Good pumps are very quiet (or should be) and you shouldn't even hear them...if you do, there is likely something wrong.
But, to address your post, if the pump is not running, the water temp over your CPU would just rise, causing your CPU temp to rise, causing your MB thermal sensors to ramp all your fans up based on that temp. So, you'd just have this endless cycle of your CPU heating up, all fans, etc. turning on for a few seconds, turning off, then starting over again. This cycling of fans (and pumps) is actually damaging and will lead to sooner failure. These types of components like to be left on if they are already started. Continual cycling isn't that good on them.

Apparently, my i7-4790k can handle cool operation with passive cooling, so I wondered if it might work well with a large 3x120 WC radiator dedicated to the CPU in a closed-loop water system.

I've been told this before, but I tried two different pumps and both were noisy. Even when the pump was placed over soundproof material, I could still hear it through everything. It's not a very quiet noise, just much louder than fans. Apparently my i7-4790k can run cool with passive fanless cooling, so I thought maybe it could work with a big 3x120 WC radiator dedicated to the CPU in a closed-loop water system. But I guess you need the pump to move the water to the radiator. Without it, the water just sits in the block and won't reach the heat exchanger.
