Frag Maniac, good that you mention the water cooling part of that, i don't have water cooling :roll: .
Currently going for the Kingston 2x1GB DDR2 SDRAM PC9200 CL5.0 HyperX
No, no, big mistake. It's just an option, that's why they call it a hybrid heatsink. It runs just fine without water cooling, note the air cooling fins the heatsink has too. The water cooling option is mainly for those whom want to get max use out of them via overclocking or setting the timings lower (eg: faster). In fact this RAM is one of the best designed I've seen in ways other than the heatsink design. Even the memory chips are 8 layered and polished for maximun heat dissipation. Sorry for the confusion, I was only commenting on the water jackets to clarify that it could be used with a copper system with no galvanic corrosion should you eventually choose to use water cooling.
