I have the very same model and also suffer from the high temperature problem. I should probably clean the fans, but another thing I usually do for normal usage is to limit the cpu speed. As root: #echo 60 > /sys/devices/system/cpu/intel_pstate/max_perf_pct Or whatever number you feel good with. Unless I am doing heavy usage, I do not notice performance penalties and temperatures do not get that high. Luis
