"OCZ has come out with what I consider one of the most innovative products to hit the market in a long time. The FlexXLC (Xtreme Liquid Convention) copper / aluminum heatsink has the "flex"ability to function as a passive air cooler or as a liquid cooled solution. The ability to watercool the memory right out of the box will allow you to really crank up the voltage and push these modules to the limit. The watercooling barbs are 1/4" ID (inner diameter). This kit has timings of 4-4-4-15 and is backed by OCZ's Lifetime Warranty up to 2.2V."
