There appears to be no difference on ram overclocks with no cooling and with sinks with active fans. It just doesn't get hot enough to matter. You are talking maximum thermal dissapations of under 2W. DDR3 != DDR2.
You can spend the extra money for the DD block that also cools the ram, but it is all bling for no zing.

What temps are these memory chips rated for?
Because 80C in my opinion is a bit higher - maybe not thermally stressed - but I'll feel better knowing they aren't so close to their thermal maximum.
About the core cooling - it has more surface area then some crappy cheap blocks... so It can't be THAT bad, although the block seems to be pretty thick? :shrug:
