DD12v-D4 on a Matrix Orbital?

While the voltage is fine and can be controlled, the Matrix orbital has a max output amp rating of 1000ma (or 1a), where the D4 requires 2A. So the answer is no. I have the same setup you just mentioned... I really wish it worked :(

I've looked high and low to an automatic controller for my D4 - but there isn't anything that can handle the current draw. You need to just get a rheobus and do it manually, which sucks, and pretty much defeats the purpose.
 
thats too bad. i was really hoping i can work. thanks for the help man.

anoone know if something like this would work?

I cant find a single Rheobus I like, to me they are all fugly. I figure with this I can hide it in the back, or even take the knob off and mount it anywhere I want.
 
I don't think that will work either. It says it's designed to hook up to a 3-pin header from the mobo. I don't think the mobo header can handle that 2 amp draw.

Just for the record my Fan Master can't handle it either. It will start the pump and vary the voltages but gets too hot and eventually shuts down the channel the pump is on. Which freakin' sucks cuz that's my favorite fan controller and was really hoping it could handle this pump. I have a few other fan controllers I can try out. I'll keep you posted.
 
Well crap!! All my fan controllers are rated at 1.5a.

Hmmm, anyone else have any suggestions?
 
There's another thread here that talks about jumping those 2 pins on the back of the pump and supposedly it will run on less voltage. I tried it with my Fan Master and it seemed to work. Before it would get too hot and kick the psu off in less than a minute. Now it can go about 2-3 minutes before it kicks it off. Each channel on my Fan Master has a little heatsink on it. Just for kicks I hooked up one of the temp probes to see how hot it was getting. This thing got up to 215f :eek: before it kicked off. That's smokin' hot!!!! I'll have to wc my fan controller to get it to work. ;) Not sure what rheobus can handle this pump.

Voltage isn't the problem; the Max Orbital can handle the voltage just fine, it's current draw (or amps) that is the problem. With a little bit of creative tinkering, you could put 24v through the MO without a problem, but when you start exceeding 1A current draw, the MO is going to heat up (and eventually melt).
 
oops I don't think that other rheostat will work try this one

went to an electronics store they suggestion trying a rheostate out of one of those electric floor heaters they mentioned it doesn't matter if it is AC or DC either will work as long as it will handle the Watts and the amp draw. That it will have to have a big ceramic to disapate the heat.
