FX6300 temperature readings

im rather confused as to what the temperature of my cpu actually is.
The basics:
AMD FX6300@4.15ghz @~1.365v
hyper 212 evo cpu cooler (push/pull configuration)
4gb corsair vengance ram
gigabyte 78lmt-s2p 'ultra durable' motherboard
500w psu

airflow/fans:
1x120mm intake fan bottom front
2x80mm fans blowing intake air over motherboard
2x120mm fans on hyper 212 cooler
1x120mm exhaust fan.

anyway, AMD overdrive says that under full load, my cpu temperature is ~58c.
at the same time, core temp claims the temperature to be ~40c.
and hardware monitor says it is around ~45c.

i know under full load the core/on-die temperature sensor is more likely to be accurate. however, which does this refer to? which temperature is likely to be correct to indicate the core temperature of my cpu?

cheers in advance

Most likely the reading in your BIOS would be correct. If I am not mistaken, the CPU thermal diode is read by your firmware and would thus be more accurate. This is how it was explained to me.

If I am wrong, hopefully someone here wil correct me on this.

There are temperature sensors on the motherboard itself. Many pieces of software read those. The BIOS reads the temperature right from the core.

Gotcha, my mistake. Forgot about the MB sensor.
