I'm planning on cooling CPU, NB and Gfx and seeing as many watercooling blocks, especially some of the best CPU blocks, are quite restrictive, wouldn't it be better to run 2 loops rather than one.

I'm gonna be using the Typhon III reservoir and from there run two loops like this:

Res -> Radiator -> Res
Res -> CPU -> NB -> Gfx -> Res

Depending on how restrictive the full Gfx block is that might go onto the radiator loop too.

My reason for doing this is that then there wouldn't be any flow restriction on the radiator loop, like there would be if for example the CPU was in the same loop, and this should result in maximum heat transfer.

Would there be any problems doing this? The only potentiel problem I can see is if the water doesn't get mixed well enough in the reservoir and alot of the warm water from the non-radiator loop would be send round and round. Considering that the Typhoon III is designed by a real enthuisiast and not some company clown i don't expect this to be the case though.

Since i don't think i've ever seen this before I'm kind of thinking I'm overlooking something here, enlighten me
