I've noticed one hot issue too. My pclos 2010 KDE is much 'hotter' than pclos 2010 Gnome. Both were fresh installed and gnome installation was a way cooler for my laptop cpu, than it was kde. CPU fan is much louder on KDE. Fglrx driver is corectly installed. No desktop efects are enabled. Frequency scaling is on. On idle cpu usage is always about 3-10% (on gnome was 0-2%)? Why is that so?
