Over the weekend yum pulled in the newest version of kde for f13 (4.5.2 I think). Since I rebooted and logged in my laptop seems to have the fan going most of the time. Gkrellm shows both CPUs are doing something, and top confirms that kwin and plasma desktop are each using between 10% and 30% CPU. For comparison on my f12 desktop at work they use between 2 and 5% cpu. I don't know what the used before the upgrade, but I do know the fan was usually off except when the machine was loaded.
This happens with only one window (firefox), and that only having a couple of tabs open.
Is this something I can change? If so, where do I need to look?
Thanks,
Chris

Depends on a lot of things.
What video driver is in use?
What arch?
Is flash installed, and any applets running in any of those flash tabs you mention?
Are destkop effects enabled? Which effects? (blur in particular, is known to cause degraded performance/load with many driver combinations).

Latest nvidia, from rpmfusion

Yes it is installed, but none of the tabs are visibly using it (I had/have gmail and a bbc news page open - the latter is static).
Are destkop effects enabled? Which effects? (blur in particular, is known to cause degraded performance/load with many driver combinations).
Desktop effects are enabled. I had blur enabled and I've just disabled it. No immediate effect - the fan is still spinning, though the cpu percentages are now down to 10-15%.
Switching off all desktop effects makes a big difference. kwin is no longer in top's list of cpu hogs, and plasma desktop sits around 1% until I actually do something, when it goes to around 15%.
Thanks for your help.
Regards,
Chris

I think it was shadow that was actually doing the damage on my laptop. I started disabling the effects I didn't care about until the cpu dropped.

1.- Reset your KDE Settings by deleting the ".kde" folder of your home folder
2.- Disable all desktop effects
3.- Get Chrome or another browser
4.- Customize your KDE as you like
I have the same problem with KDE with nvidia drivers - it seems worse with the latest ones from rpmfusion, and worse in 4.5 compared to 4.4. (Not sure when the change came in, first betas of 4.5 seemed fine).
There are a bunch of bug reports already (eg https://bugs.kde.org/show_bug.cgi?id=234463) - though there seem to be multiple issues and a lot of noise in the bug reports. For me, turning off the blur effect helps, but not much. On my laptop I have switched to gnome for the moment as it gives me approx 50% more battery life in normal use (OO Word + calc, kmail, firefox, amarok, R etc) than same apps under kde. KDE apps under gnome are a pain though (you have to start kmail twice to get akonadi running first, super slow scrolling in akregator etc etc).
Nouveau didn't work well for me last time I tried, but will probably make the jump to F14 and try again sometime soon.
sorry! M.

@moabi2000: Try out to reset your KDE settings as I mentioned before, then turn off the desktop effects and see if KDE's behavior get's better. About the Opensource Graphics drivers a lot of people say that they work great in F14!! Make the switch if you want.
Same probs with a new test user account.
I use the 'expose' effect a lot, it is a great productivity tool, so don't really want to turn off effects.
You allude to another problem - I can't simply nuke .kde since there is a lot of data in there. Why aren't there two directories - .kde-data .kde-config?

FWIW I just tried the nouveau driver in F14 and am very impressed. KDE desktop effects work great, and scrolling is much smoother than with nvidia blob and less tearing. Google earth is a bit slow but perfectly usable.
However, still have high kwin cpu use, so not necessarily nvidia-related. Reported here: https://bugs.kde.org/show_bug.cgi?id=234463
I would strongly suggest giving nouveau a try, it is MUCH better than even 6 months ago, at least for my hardware (quadro 140).
Cheers M.
