For those who want to take the jump to water cooling, 2FastCPU wants to tell you about the Z4 Copper Intercooler Kit. here's a snip:
"This kit comes with many parts, all which we will be explaining in extensive detail. First, we'll start off with the radiator. The radiator coming with this kit is 5x7" and they also sell a 12x5" as an upgrade. For most, the smaller 5x7" radiator will do great. A notable feature of this radiator is it has the capacity to have two 120mm fans, one for each side, allowing overclockers to gain even better performance if needed."
