All have shown issues and while it's fun to see such things the problem is that all seem inaccurate as you noted. And to make matters worse for you if you get one that does work but looks wrong, so far all the others will give you the same reading.
It's a shame you didn't include make and model since at the office we have a Tosh with that APU and I would have tried Speccy but the missing detail means I didn't.
In the future please try to post the full detail or flame me if I missed it as some may know that on such and such model you take the reading and divide it or such.
I have noticed my laptop seems to be overheating a bit and I want to monitor my internal temps. I've tried Speccy and I feel like it is really inaccurate because it says my cpu is basically always running at 80-111C. I've tried Core temp but I don't think its compatible with my A10-4600M (says 0C). I've been using AMD override, does anyone know how accurate it is, or if there are any better programs specifically for AMD? Thanks!
