Thanks Shazza and Skinnee for your fast response to my questions, you have been very helpful and I do appreciate your time and effort you have put in to answering it.
I will look at the list of items “Aquero/TMS-200/HeatMaster “you have mentioned for me later Skinnee, as I need sleep.

Just one other question, the DDC 3.25 pump is only rated to 60 degrees C.

If I was to have my set-up running in a TJ07 like, res (home made large in size) going to-DDC 3.25 pump's (in parallel, hopefully watercool's dual res top)-rad XSPC 120x2-rad XSPC 120x4, then split into two, one line to the CPU i7, and the other one going to graphic’s cards, 2x GTX 285 SLI, then both lines back to res/ end of loop.

How hot might the water get when it gets back to the pump?

I know you can only guess, however, if water temps in the res do reaches 60 degrees. Do the pumps die fast at this temp?

I understand there are so many variable’s. Now I have written the question out in front of me. I think I may have lost the plot asking it. Perhaps I am just too tired to think straight.

Hope you are both well.
