Athlon x2 High temps even when not playing games.

It is high if it is in °C on idle, check if your cooler needs cleaning dust and lint will hinder it in cooling your CPU properly!

I noticed you have the black edition, did you overclock it? If so, are you using the stock heat sink?

Athlon 64 X2 runs hot... the 6400+? Very hot.

your not wrong but even on stock cooling it should max out ay 55'c

clean out the case/fans and vents of dust. clean out the cpu hsf and make sure your pc can breath (you dont have it in a closed box.
go into bios and turn down the vcore from 1.45 to 1.35 the lower volts may increase instability or may have no effect what so ever but bring a temp drop... so its worth a try.

It's not overclocked. I've also noticed it runs at 80 when I play minecraft, but when playing SKyrim it's stable at 70!!
Shutting down to clean my pc...
