A 15.3K cheetah runs at about 32dB idle btw - high speed scsi drives are available below 30dB that I've been able to find.
bob, as volts go up amps also tend to rise for CPUs, you'll often find overclocked CPUs exceed the maximum ratings for current draw specified by AMD. I estimate that for 110W at 2400MHz you'd be looking at 1.95V, which is quite reasonable. Roughly speaking this gives a current draw of 56A (this is only an estimate is the power formula is not exact and CPUs are not ohmic devices).
The general cpu power draw estimation formula is:
P
oc = P
stock * (f
oc / f
stock) * (V
oc / V
stock)^2
