Well, that looks a bit like the system I'm setting up....
Only I use P4
For my setup, I chose 2 different loops. One all copper 1/2":
- 2x MCP600
- WW cpu
- D-Dek z chipset
- Innovetac "pateched" GPU (don't lauch.. I have a Gforce4, and I don't want to OC it..)
- Dangerdan Bay-reservoir.
setup:
res - pump1 - pump2 - double heatercore - ww
I will keep the outlet of the WW split, let it go through de GPU and NB.
After this I have one single Heatercore and one BIX. Then back to the bay res.
For the rest I'm making a whole aluminium loop.
This will have the nice small res+ dual pump from Koolance. I might put in one extra pump, as it needs to go through 5 and 6 mm ID

this will have :
- 3x koolance HDD coolers
- home made Mosfet cooler
- South bridge cooler
- PSU cooler
- System Memory cooler
- GPU memory cooler
- If it works out (still designing) back of CPU/Motherboard/mosfet cooler
The alu loop will have the koolance radiator and one radiator of a piaggio.
All exept the koolance EXOS will be build-in into my chieftec tower
This should be able to beat all heat problems

(I like to go for the 100%
