This is rather inaccurate. First of all, the G5 does not *require* 9 fans; Apple *chose* to use 9 fans because then all of them can run very slowly, generating as little noise as possible while keeping the machine well within its normal operating temperatures. The liquid cooling is also fairly unnecessary, and is mostly used because the G5 is a much smaller chip than any of Intel's chips, hence its power dissipation is much more dense. So, even though the G5 takes significantly less power than most Intel or other x86 chips, cooling is sometimes more difficult because everything is so dense. So, in reality, the cooling system in the G5 is incredibly overpowered for what it's doing.
