Important question, Can I use a single pump if one LCS pump is broken!!!!!

Now I have a really insane question, if I do the plumbing right, could I run my system using only one pump?

Yes one of the pumps just up and died on my after the PCB released the magic smoke and burnt itself (see pictures). Now I think that I have found a replacement PCB, but I would like some help identifying if it will work and also if anyone might have some spare units or something like that, or even a place I can get the parts cheap(ish, basically not $70 to $400).

In the mean time I got to thinking and believe that I have mapped out a loop that could feed both loops from one pump, now I know that there might need to be some wiring modifications done, but I was just wanting to know if I would be able to pull this off and have it run just fine, or if it would burn the motor out? Also would adding a resistor to the wires to bring the voltage down to 10v - 11v be OK too?

OK!!! Update this is my plan for a single pump dual loop. Please excuse how crude it is, I am needing to get proper tubing (and maybe fittings and joints and maybe even pipe), but I want to know if this would work at all. So I will just do a quick test to see if it can pump water through it.

Please if anyone knows if this will work please let me know ASAP.

I did find some other threads in google of other people using alternate pumps (other part numbers), but I have not seen anyone convert a dual pump to single pump. In theory it should work as long as the pump can keep going. @HrutkayMods has several G5 videos on Youtube about converting LCS to air cooled as well.

What pumps can I use? Is it able to be any type of pc pump? Also where would I get the air cooled heatsinks?

Also it was kinda working bleeding the system is a nightmare. And I also found out that the pmv PCBs die because of a particular component.

I will look into the pump options.

There's a couple Quad G5 air cooling threads on MacRumors. They use third party air coolers - 92 mm.

Could you maybe link that thread?
