What is your definition of considerably hotter? 1F, 1C, 10F, 10C? What is the ambient temp? Is it hotter today than yesterday's ambient temp?
Doesn't surprise me at all. I have an old netbook I use for comparisons and it seems to run noticeably slower, I'm certain Bat said his old PC ran noticeably slower as well. I've read here that Ms has raised the minimum specs for X86 to 2 Gb ram for this release. Everything points to Windows AE needing more resources to run than TH2.
