CPU temperature

[crisbduck]

So I was using the asus temp software to measure temperatures but decided to try core temp and the temperature is 18'C lower, 39 vs 21, thats a huge difference so which should I be trusting?
btw its an amd motherboard running a 1055t 95w if that makes any difference
Thanks for your time

There's also a motherboard temp on the asus software at 26, really hoping core temps more reliable but it seems pretty low

Downloaded that and the TMPIN0 is under the 5850 and is at 40, motherboard monitor is at 39 and from the cpu tab all cores are at 21/22
