How to check CPU temperature on i2x00 series device?

How can I query CPU temperature? I've read through BIG-IP mib files and tried snmpwalk but it seems that CPU temperature info is not available on this device. I'm getting only following info when querying "sysCpu" branch:

snmpwalk -On -c public -v 2c sysCpu
. = INTEGER: 0

And that's it. Querying sysCpuSensorTemperature or sysCpuTemperature returns error that there's no object available at this OID. I can only get sysChassisTemp but it's not really what I'm looking for.

I think cpu temperature information is available (at least should be I guess) since I'm getting TCTL-Delta temp high(crit) alerts in AOM. So I wanted to check out what's is exact value of temperature.
