  • I will try the clock trick thx! btw, I use psensor to monitor the cpu temperature; there is a single temperature that gets crazed on high load k10temp-pci-00c3, the machine beeps, and if beeps too long it shuts down.. I dont care what other applications are doing, even if IO, the application that has focus should work at best and the other should calm down; I improved the cooling system, may be not well enough.. but I am still not sure it will help considering the load goes above 4.0 (on quad core)? so I am focusing on lowering the load, even if I get a better cooling system (with peltier).

  • You might also be able to turn off a core or two and not have to reduce the clock speed. A computer that is using half its cores is infinitely faster than one that shut down because of thermal overload. Commented Oct 7, 2013 at 17:16
  • but my system load gets above 4.0, if I shutdown any, the limit will lower too! I only get the overheat when load goes above 4.0; below it the machine runs fine! thats why I believe even with a better cooling system I may still have problems.. Commented Oct 7, 2013 at 17:27
  • If the load average (that is, number of jobs in the ready-to-run state) goes above 4, the others will just have to wait. You can't use more than 100% of a core even if there are 23 jobs ready to use it. Commented Oct 7, 2013 at 23:10
  • I just did something interesting; I put all processes to nice 19, less the one process I am currently using; the temperature on psensor graph got much more normal now, it was very unstable (too high/too low); also I saw the system load go to above 6.0 (once only) and the temperature wasnt that high! all processes were working properly as expected also. I think this need more tests to have some better conclusion... Commented Oct 8, 2013 at 2:01
