PowerMac G5 Cooling/Sensor Issues?

Appleinsider points to sensor issues causing delays in the PowerMac G5 updates.

According to a "reliable" Appleinsider source, "Apple was recently forced to completely rework the internal temperature sensors inside the current G5 case design to accommodate the new 90 nanometer G5 processors."

The information is somewhat consistent with early rumors of cooling issues with the new PowerMac revisions.
