I understand very well what you are saying. The reason i opt for the block without the extra reservoir is that if you look at the original block designed to normally go with the OMNI system, its just as large, if not larger. Now of course I do not have inner volume measurements of one block vs another in terms of how much liquid it can contain, but I think they are awfully close. Given this, wouldn't the limitation you spoke of earlier not exist in this scenario???... I mean I read many many positive feedback from those whom have used the OMNI system in its original stock form, and they are all positive.
I just want to say that in essence, all I am doing is changing one type of block for another, and with this there is direct contact, if you would look at the OMNI, one block takes heat off another, hence there is a loss of heat transfer between the two metal objects.
See original block assembled:
Anyhow, I read on another forum that someone did exactly something like this with an i7 based CPU, and it worked out well... Yes I am aware that GPU's get way hotter than CPU's, but again, I think even this with what I have in mind will give me improved results over what I have now. I am not taking things to an extreme.
So if anyone has any suggestions as to my other concerns/questions, please let me know.... and they are:
Do I add extra coolant liquid to the current one?
Do I simply replace all the current liquid with a different one?
How do I know how much liquid is enough?
What liquid should I use (just distilled water)?
My prev Question about the Dye?
My prev Question about the anti fungal/corrosive etc... liquid?
What would an educated guess be as to how to connect the two 1/4' tubes to the current radiator:
Thanks for all the input from everyone so far.
