Comment 7 for bug 1389077

Yes, intel_powerclamp is set to default to 85C as the default thermal limit. It spawns these kidle_inject threads to help slow down and cool the cpu. I believe there is a way to set the threshold higher, but it's probably not a good idea. It would be better to see what is causing the cpu to get that hot. Is the fan working as expected, maybe it's gotten really dusty and needs a cleaning. I know that minecraft is pretty graphics intensive, maybe run top before kidle_inject kicks in and see what the top processes are.
