I know what you are talking about goodie. Thought it was just a visual bug in Everest. I still believe it to be a bug, and you didn't reach that temperature. However, you said Asus probe reflects the same thing???
I've seen 3 cases of this so far. All on Maximus Formula boards. So, I'm thinking it is either a faulty sensor, or some bug in the DAC or reporting at the hardware level. Mine spiked up to 90c! I freaked out until I saw the cores were at normal load temp.
Or maybe just a quick BIOS flash will fix it
I just don't like to flash the BIOS if I don't need to. Everything is working great now. No sense in futzing with it to fix a not even irritating visual bug.
It may just be an Asus problem. Now that we know it's reproducable, I'll shoot Asus an email and post any solution I find here.
