Are you *sure* the G5 coolers are liquid coolers? those look more like air coolers.

If using multiple radiators, you have to find a way to split the flow between the two - the simplest way I can think of is two pumps, one dedicated to each radiator.

I don't see how you'd mount those bulky things inside a case, since your picture shows them resting on circuit boards - as is wont for air coolers.

SO overall I think your plan is ill-advised and ill-conceived.

they are air cooled.

I was considering having 2 separate cpu blocs strapped to them in order to have heat transfer to the large heath sinks.

just wondering how good of an ideea is that.

This is how it looks without the circuit board.

the excess metal will be grinded off.

The positioning of the coolers would be ontop of the case, not inside.

not even with fans strapped to them?

Yeah I agree, I can't imagine those parts would be compatible outside of the case, or would be compatible with current Intel sockets.

Nope. The problem is that all you would be doing is passing the water through another block strapped to the heatsinks. The surface area would be the same size as a CPU block. When water goes into a radiator of a normal custom loop or CLC, it is designed so that the heat is dispersed over the entire area of the radiator and onto the fins which then is cooled by air from the fans.

What you have in mind would be so bad at efficiency that even most mid end air coolers would perform better because the water would not have enough surface area to dissipate all the heat causing warmer water to be sent back through the pump and to the CPU water block.
