I just noticed an odd thing on my HD 6870.
I don't normally run CPUID HWMonitor outside of gaming sessions, but I noticed after leaving it on, with Facebook open, the temps rises to ~60c. It normally idles around 46c. As soon as I close the browser (IE11) it drops back down.
It's not a big issue, as I have a new GPU coming for Xmas, a Sapphire R9 270 Dual X. I was just wondering if it's normal.
