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.

How have you come to this conclusion? A guy at the jungle tried to passively cool his ram and WC his core... Well the mistake ended up costing him $400/his 6800GT. If anyone thinks it is safe to passively cool the memory on this card they are foolish. Here's a link to the forum where the guy talks about how he fried his water cooled 6800 GT while passively cooling the memory.

The dangerden WC block that covers the core and ram will definitely save you some frustration and isn't all "bling for no zing"
ps. the guy rma'd the 6800 after he melted it and donated the $400 to three different charities, then bought another one! he defnitely won't be passively cooling his next 6800
If you don't want to WC the 6800 go with the leadtek cuz it is overclocking to 425/1100 in my rig air cooled and that case is stuffy too.
