Liquid Cooling More than One Component?

static0verdrive asks: "I am new to liquid-cooling, and I have designed a system for use in a micro-ATX OpenBSD server, with the following layout: Fillport > Reservoir/Pump > Y Split (one to CPU and the other to chip-set) > Y Reconnect > Radiator/Fan > Back to the fillport. I don't like the idea of having the hot coolant coming from the CPU going directly to the chip-set, hence the Y split. Could this split cause any problems? Would there be a difference in pressure (considering the CPU is most likely a lot hotter) that could cause an issue? How would you handle liquid-cooling more than one component? What if I wanted to cool 3 components, such as in the case where I add a video card to this setup later on?"

I think the idea is potentially suspect because you have no guarantee that both sections of the split line will have equivalent flow resistance. if one is more resistant than the other, more of your flow will go to the path of least resistance. It seems overkill to liquid cool the chipset's core chip. I'd suggest doing a series connection, cool water going to the chipset then CPU because its heat output should be much smaller than the CPU.
