I hear what you say but I think I have got a solution to my problem. That is a bit cheaper than my original solution.
I saw a C-Systems CSP750 Mark II for 37$ so I thought why not let the to system share water. I will run the small loop with chipset cooler and CSP750 pump into the watertank that the Big loop have. In that way I not have to buy a extra radiator.
And I just have to drill two extra holes in the tank. This way I will not have the trouble with any chipset block restricings my flow in the future, and can add things like voltregualtions blocks and so on to the small loop. And that the pump can be connected to a 3-pin on the motherboard (maybe the 3 pin fan connector from the chipset fan) and that's just bonus for me. If this is a extremly bad ide just tell me and I will go and buy a new board =)

This will maybe be a bit expensive, but for me building and solve the problems is probably the biggest reason I do this. For me it would be cheaper not to buy a water cooling system at all and go for a air chilld system. But it's just so damn fun building and planing and hacking up the chassi to make it all fit that I just can't stop doing it =)

Thanks for all the help I really appreciate it!

Edit: Will 2 loops sharing watertank cause any problems??
The two loops will looks like below.

Big loop: Pump (MCP655)--->Cpu--->Singel Radiator--->Tank--->Dual Radiator--->Pump
Small loop:Pump (C-Systems CSP750 Mark II)--->Chipset Block--->Tank--->Pump
