2.3.0, unexpected average temp, no individual readings

[superman-lopez]

I realise there are a number of closed issue cases on this topic since 2.1.0. However I feel there is still something wrong with the average temperature that is calculated/shown.

I have included a screenshot of Macs Fan Control and Fanny, the independent sensors in MCF all show much lower temps than the average that Fanny is showing. Also when I select specifically core 1 through 4 in Fanny the temperature reading is --.

This is on a 27" 2017 iMac, macOS 10.15.3.
