I switched from Gnome Elyssa to KDE Elyssa CE evening before last. Gnome Elyssa usually ran about 105-110F (38-41C) during inactivity, and up to 125F (52C) during periods of heavy CPU activity.
Now, with KDE, the system IDLES at about 125-130F (52-55C), and last night, while running VirtualBox, got up to 165F (74C)!
This is probably at the upper end of what my system is supposed to run (it's an AMD Turion X2 64 Mobile Technology). I don't know what the max temp spec is, but I know not many processors are supposed to run this hot, and even fewer are supposed to run hotter. If it is hitting this temp frequently during regular use, then my CPU will not last long.
I open ksysguard, and I find no processes consuming over 5% CPU. Xorg, which is usually a resource hog, is only drawing about 2-3% CPU. Firefox stays at 0%; even so, the temp doesn't drop when I close it out.
I installed and ran sysvconfig, disabling several of the services that I know I don't need, with no effect. Still runs way too hot.
I thought maybe it was a KDE problem, so I installed XFCE. Logged in, and opened Ksensors. It dropped the temp about five degrees, but it still ran way hotter than Gnome Elyssa did. And, if I'm not mistaken, Gnome should require more resources than XFCE, right? So, I don't think it's a problem with any of the desktop environments. Beyond that, I'm stumped.
What could be causing this? I just installed it day before yesterday. I can't install anything else that might run in the background, out of fear that the temp will hover at a constant 140F (60C) or higher.
Does anyone have any ideas what might be causing this?
