I just use a 92mm fan nestled in the tubing for my waterblocks, or you can thread some string/elastic through the fan and hang it off the RAM.
It was the RMA process that put me off the OCZ modules. Great service from the OCZ people, but they wanted to send the modules to the US, and as they were 350 at the time, and quite heavy, it worked out expensive.
Those HR-07 memory coolers, are what was the Team xtreme RAM that I had, and they all died within days/weeks.
The Geil memory wont even need any extra cooling (i wouldnt think).
