What does this software-controlled clock disabled (full speed) mean in this output? Can I manually enable it again so that system would not run hot like crazy?Recently for the past couple of months I have been noticing that when I start firefox my system fans go mad and CPU temp rises significantly by at least 5Celcius. When I use Google plus the CPU usage reaches at least 40-60% and I assume _javascript_ is making the system go crazy. This rarely happens in chrome though. I found this same behavior in other distros as well. Debian unstable, Gentoo, arch. I thought if I switched to some recent versions(stransky's copr packages) of Firefox 29 would help but to no avail. Did anyone else notice this kind of thing on their systems?
I think its specific to recent Intel core processors.my output of x86info isx86info -m
