All of this is totally irrelevant because the 300 series stainless steel parts of the D5 are totally isolated from any other metal parts in you cooling loop ELECTRICALLY. My original point in bringing up the D5 was to demonstrate a REAL example of dissimilar metals that have been in everyone's cooling loops for years without any galvanic corrosion rather then resorting to the heard it from a guy who heard it from his brother type anecdotal evidence we normally see posted.

Here is the link again:

Keep in mind that that is written by a professor of applied sciences...

As for the CPU leaking an electrical charge to the block. I would doubt this but I can't say for sure. It would not matter if it HAD happened though because adding electricity to an OPEN branch still would not provide a closed contact electrical coupling. For that to happen the cpu block would need to be in contact with another dissimilar metal in the loop still...
. . .and you completely ignored my Koolance example which is a far greater distance of metal nobility than the stainless/copper example.

*sigh*Agree to disagree it is then.
