well, before I start PMing people, I would like to know if a independent loop with a Thermaltake Tide Water Plus will give a overall better temp for all my components, since the CPU is also being cooled by the 1/2" loop.

Tell me if moding a Tide Water Plus this way will give better temps overall:
The WC case will be verry close to the case, and the overall tubeing will be verry short to maximize head pressure. My plan is to change the Tide Water Plus's design from a parallel cooling solution to a series cooling solution with shorter transparent tubeings, a T-line instead of the reservoir, the copper radiator will be cooled in between two SanAce fans (the spot with less blind spots that I found), and the tubeing wont be bent as narrow as the Tide Water's interior. Without the mod these blocks (Which have a copper interior) could cool a 7950GX2 core at about 35 C Idle and 42 C Load. They will probably perform even better with this mod.

This is how the Thermaltake Tide Water Plus looks like out-of-the-box:


This is how I want to mod it:



It looks like a pretty good solution for those who want to OC a 7950GX2 and cant find or dont have the money for a custom block.
If the custom block kills performance on the whole 1/2" loop, or if its too complicated to build, then I will probably go with the Tide Water Plus solution shown above.
If this solution it more efficient than running it with the 1/2" loop, is there a custom loop that will perform about the same or better that will cost cheaper?
