In a round about way, . . . yes.
The Mix 'n Match builds were coming along nicely and I was planning what kind of pump setups and controls and displays to go with.
As it turned out, Lamptron was just releasing their new CW611 controller that's designed for water coolers, as each of the 6 channels has a 36W capability, and each can be set as a fan, pump, or flow meter controller.
Having a flow meter display read out in gpm seemed like a nice idea, as normally they read in milliliters per minute, and you have to have a conversion chart handy
Anyway, I got two of them for the M 'n M builds, but since I have all PWM pumps, and the new Lamptron controller is the usual variable voltage output type, if I wanted to have temp referenced speed control for my pumps, then I'd need to build a "Voltage to PWM" translator . . . . .
So I did, here: http://www.overclock.net/t/1395117/diy-voltage-controlled-scalable-pwm-controller
Anyway, as it turns out, after so much creation and development, that I really don't see where there's any advantage, and there are disadvantages, to having the pump controlled like a fan based on temp.
So ultimately, I kept the really perfect manual PWM controller portion of the system and designed a PCB to make some up.
Of course about the same time, Koolance comes out with this nice little bay mount flow meter display that reads directly in gpm, or lpm: http://koolance.com/dcb-fm01-flow-meter-adapter-with-display
So I got 2 of them for the M 'n M builds, and I'm going to put the 2 new Lamptron CW611's in the stretch and take advantage of all that display capability for the fan speeds, pump speeds, and flow rates and water temps for all three loops. I'll also gain temp controlled fan speed as well, really a plus with 2 dozen rad fans running.
Of course I needed to design a circuit that allows me to let multiple channels control from 1 sensor's input to get that. . . .
And yet another pcb I'll be trying to make tomorrow, having already designed it.
I'll be moving the FC9 controller and both X-Vision displays from the stretch, plus 1 new FC9, to the M 'n M builds to control and monitor fan speeds and pump rpm, putting in the new design PWM controllers to control the pumps' speeds, and the new Koolance flow displays to monitor the flow rate.
It works out to be a win for both the stretch build, and the M 'n M builds.
I just have a ton of electronics work still left after having done so much already, that hardly even shows since it's so peripherally related. . . . . . . . but then that's part of what sets my builds apart.
Here's the Lamptron CW611 thread, starting from when the first units were in the hands of end users: http://www.overclock.net/t/1357575/introducing-the-lamptron-cw611-water-cooling-assisted-fan-controller/110
