In the review you stated: "The battery backup is an odd feature. The Eudemon draws power from the PC power supply. If the PC power supply fails then the PC shuts down. Cooling is no longer the main concern. The odds are astronomically against only the 12 volt lead that powers the Eudemon failing. If it does then the fans would shut down and bigger problems would arise very quickly."

You completely missed the purpose of the battery. It is there to keep the clock running when the PC is turned off...without the battery you'd have to set the time and date every time you powered on.
