But I still love my 655 because of the fact that it perform, and never failed me.
Maybe I read this wrong... but are you putting 3 pumps in the same loop ? You say 3 loops, but you only mention one block, which is the CPU...

I guess I am just confused as to what possible situation would require three separate loops when one large loop would be more efficient.

Also, you are assuming people use a reservoir at all. If anyone is concerned about space, they use a T-Line.
