The quad G5 has a much lower rate of LCS failure or compromise than other
liquid cooled G5s. If it were, say, a dual 2.5 like my folks', I agree
I'd check the LCS first. But on this quad, I'd do the clean-up and thermal
paste renewal first because you'll have to do it anyway, and it's more likely
to be the issue. For relative failure rates, see this handy table:

Of the three quad G5s I have personally owned, none of them had an LCS issue.
The one that's "dead" fried its logic board for some other reason, and the
other two are still going strong.
