Roughly the same:
[root at bast:/home/dan/tmp] # smartctl -a /dev/ad2 | grep -i temp
194 Temperature_Celsius 0x0022 080 076 042 Old_age Always - 51
[root at bast:/home/dan/tmp] # smartctl -a /dev/ad0 | grep -i temp
194 Temperature_Celsius 0x0022 081 074 042 Old_age Always - 49
[root at bast:/home/dan/tmp] #
