Note that power consumption won't change with the "office friendly" kit.
So the unit would still dissipate the same amount of BTUs. (but perhaps
less air movement but air will exit at higher temperature).

The power supplies have their own fans inside. So pulling one out does
reduce fan noise, but those are not the big noise producers.

Since motherboard power consumption will remain the same, the one
remaining power supply will get hotter since it will handle all the load.


If I look at my Xserve, the firmware controls fan speed and fan speed is
dictated by various temperature sensors on the motherboard.

If you change fans to have less CFM and tolerate higher output
temperature, then perhaps the firmware needsto be updated to reflect
that. (assuming that the IA64 box has variable fan speed controls).

In the case of x86, it has variable power consumption based on CPU load.
 Not sure if that IA64 thing has that level of sophistication. The Alpha
doesn't.
