i made a previous post about my fan going crazy but that was me not communicating very well as that was what i was hearing and in fact looking at the cpu usage it was jumping around. I have the same problem on malaria control, so im on world community grid right now, was on docking. |

You might already know this stuff, but in case you don't, and the above is correct then on the latest version of BOINC that setting is under Tools > Computing Preferences > Processor Usage > Use at most X CPU time. If that's less than 100% then BOINC will make the project application take a break from crunching for that percentage of every second (I think it works on the basis of 1 second anyway). |

yes i am aware of the 100 percent usage setting issue and took that into consideration, i still have the same problem. |

I believe BOINC achieves the CPU % desired across a 10 second interval. This still provides the desired control on heat levels, without imposing excessive overhead on the computations being done. So if you tell BOINC to run with 70% of CPU, it will allow tasks to run for seven seconds, and then not allow them to run for 3. I word it that way because these tasks are still marked to run at low priority. So if higher priority work is ready for CPU during the 7 seconds, the tasks may not get 7 seconds, they might only get 4. The 3 second suspension from running though would always be 3 seconds.
