Amd 6300 fx 6 core. I recently changed cases. The case has 3 fans, two on top and one on the back. Im useing the stock cpu fan. Idle is fine, running anything im fine. But when I download anything, mainly large files due to duration, the temp has climbed to 69c. As soon as the downloading has stopped it goes back down to 40-50c. Is this normal? Could there be an issue somewhere?
