Automatically adjust the pump speed

post #1 of 7
Thread Starter 
is there a way to control the speed curve of a water cooling pump ? i have the Swiftech MCP655-PWM-DRIVE

basically i would like the pump to totally stop when the CPU temperature is under 50 or something like that.

MSI Afterburner allows to do the same thing with GTX980 fans so i would like to do it with the pump of my CPU closed water cooling. objective is to get a 100% silent PC when not gaming

Well presumably, your motherboard is controlling your PWM pump so whatever software your motherboard has for controlling fans is what you would use. Or barring that, the bios.

With that said, it is unlikely that it allows you to turn the CPU FAN completely off and even if it does, it would just turn right back on again; with no water circulating the CPU is going to heat up very very fast even with no load on it.

That's a very bad idea the pump would always be starting and stopping since a water block can't dissipate heat like the radiator of a gpu without movement of the cooling fluid at all you would either bake your cpu or burn out your pump from it starting and stopping all the time.

If you it quiet go full external and put the pump and rad s in another room.

I agree with the post above, if you want to go 100% silent just go air with an passive fan curve. Your CPU will never stay under 50C with the pump shut off at idle.

the pump doesn't shut off on a pwm. that isnt how things work and isnt what a loop is designed for.

Just set a corresponding RPM curve on the header those fans are connected to.
