New mobo same temps...
I'm gonna try with a lidded 3400+ i think this athlon is bugged.

I've a K8V SE with a 3400+ in an older case, and it runs pretty hot. It has the stock all aluminum cooler, Noctua thermal compound, and under load the CPU varies between 50° and 60° with the case temp at 40°. It's overclocked a little (FSB is set to 212 MHz) and it never has an issue when I'm playing a game. For example I just ran 3D 2001 - CPU temp was 49° at the start, 58° at the end.

Mine idles at 60 and it's delidded.

Ok just tested a 3400+ lidded with the prism.
39 in idle, stable.

Maybe you should look into some other means of measurement. I wonder if the CPU's thermal diode is just inaccurate. I have a feeling I've read about this with the Athlon 64.

Hm, I know that back in the day Intel had a thermal diode bug, when it refused to pick up the temperature below a certain threshold. Maybe that's the same thing? Have your tried doing stress test to see the difference between idle and full load? If the diode is "stuck", you won't see any significant difference.

I tried another thing, heavy modding the bracket and leaving as much space for pressure on the die, well i was able to go as low as 47c in idle, this by adding pressure by hand.
By all accounts this should a form of overheating with any athlon 64 at idle and the temps are correct or i wouldn't be able to go as low as 47c i even saw a glimpse of 46, this with a prims mind you, on the damn naked die.
At this point i don't know what to think.
