No, you link them by running two in series. Instead of going from the C1 to radiator, you go C1 to C1 to radiator.
Is series linking multiple C1s still the way to go?
I've got my hands on a couple of C1s to play with. I know they are way past state-of-the-art these days, but the price was right and I've got access to some cheap electricity so I thought the time is ripe for adding to my meager mining setup. I'm not doing it to make money... more for the fun of it I guess.
The guy who had them before me used one pump/reservoir then a Y adapter feeding coolant to both C1s, then two radiators, another Y and then back to the pump/reservoir.
Running them in series would certainly reduce the number of junctions in the coolant hoses which would make me sleep easier at night.
Lunokhod.
