Don't you hate replying to your own posts.  Restarting the 
dataeng service has helped a lot.  Reading the fine 
Dell SNMP manual again after posting is also useful.

snmpget -v 2c -c public localhost 1.3.6.1.4.1.674.10892.1.700.20.1.6.1.1
SNMPv2-SMI::enterprises.674.10892.1.700.20.1.6.1.1 = INTEGER: 430

snmpget -v 2c -c public localhost 1.3.6.1.4.1.674.10892.1.700.20.1.8.1.1
SNMPv2-SMI::enterprises.674.10892.1.700.20.1.8.1.1 = STRING: "PROC_1 Temp"

and the fine manual explains that the temp unit is 0.1 C.  Perfect.
