I have both a DNS-323 with FW 1.06 and a DNS-321 with FW 1.01 running in the same room with an air temperature of 67F/19C. Both the 321 and the 323 have their drives in standby and no server services are running on either system. Both systems contain one WD 500G drive and one WD 1T identical drives.
The 323 shows a temperature of 87F/31C and the 321 shows 109F/43C. The fan on the 323 is always off and the fan on the 321 cycles on and off, but is off at the present time.
I would not expect to see such differences in temperature between the two units, so there is either a temperature calibration problem, a bad temperature sensor or a software error. If it is a calibration issue, then the firmware should allow users to set an offset.
Does anyone else out there have two similar units in the same location?
