Never used a water block, so don't know how it works. I just think that expensive electronics and water usually don't match well together, therefore other coolant might work, hence my question.
Don't expect you to know, maybe others have more experience.
Oh I didn't know if you knew some other type of cooling with waterblocks thats why I had asked, but if you look at the pics there are 2 lines that run under the mobo tray, that is where my pumps are.
