Your crave made you cave.I caved and reinstalled windows 10 preview...
Yup, I was constantly reading this thread, had downloaded the iso a while ago just didn't install.
What web browser is everyone using? I did notice internet explorer is also a culprit in high fan use. I changed over to chrome and haven't had any issue. Does Opera or Firefox work better? Or maybe another browser? I've read for Windows 8 internet explorer is the best for battery life but with the fan on time with Windows 10 I think those stats may not be the same.
