Notebook is overheating, couse BIONIC is not paying attantion to the CPU temperture
cant do anything if BIONIC is not starting the reduce itself on high CPU temperature i know u can set the CPU usage to 10 % but it change it back to 40 % with a reboot or just byitself..i m really angry about this. BIONIC seems not to take the user setup integrity serious |

I was not aware that BOINC had a throttle control based on heat of host. tell me more.
----------------------------------------I have used TThrottle with great success for this purpose. For a laptop I've used a cool pad with fans or sometimes just slightly elevate to ensure intake fan is not blocked. Also, I've been able to reduce the temp of a laptop but blowing out the dust with caned air through the intake and output air ports  |

thats the problem, it DOESNT check the cpu temperature and it DOESNT reduce the cpu on high temperature!!!

Most modern laptop CPUs such as my I7-2670QM throttle themselves when it gets too hot for their liking.
----------------------------------------EfMer's TThrottle tool as augmenter for BOINC is great on non-hyperthreaded devices, Windows only, BUT it's in effect doing the same as the internal BOINC % of CPU time control, with much finer resolution, i.e. at end of day you still see that the computed/reported time is much less than 24 hours in a day (per thread). So what have I done in recent times when having little personal use... just set the CPU Ghzs down in OS power management to the point where it's not blistering me fingers at the touch and just let it run at that speed and the fans are not howling. (Regrettably ThreadMaster nolonger works under W10, else I'd have used that). Of course, you have read the Dust-Bunnies thread in the chat forum. Can of compressed air, insert tube in fan exhaust/ventilation ducts and blow as the gunk collecting there is often much to blame... easily gain 10-15C drop in operating temps if really tardy.

Sek made a good point. Laptops are not as easy to clean out as desktops, but still need regular cleaning of the cpu fan. Very important to keep dust out, especially on laptops. As B2I mentioned, a laptop cooler will force cool air over the bottom of the laptop, helping some as well.
What model laptop is it? What processor? How old? |

its very nice u trying to help me out. but thats not my point of view.
i just want:* the program should respect user integrity by setting it on 10% cpu usage and stay there. and the program should watch the cpu temperature and reduce usage by 75C i have problems with my notebook: the Thermal Compounds is waste, the cpu Thermal Compounds and the graphiccard Thermal Compounds is waste, it should not be there anymore (notebook is 6 years old.) couse notebook is shuting down when i open a stream and youtube. (overheating) i m not good in opening a Notebook and cleaning it and i m not good in puting better Thermal Compounds to the cpu and gfxcard. i dont want to break anything. so i cant do anything about it. |

A) With the compressed air approach, NO opening needed... keep the can vertical, spray-head up, as you don't want to freeze the internals while pushing air in at high speed (which drags the dust out through other vents)
----------------------------------------B) Of course you've set BOINC in the menu to 'Run Based On Preferences'. If you don't it will run to the max. (Never ever heard of BOINC forgetting what the settings are, it just needs to be told to actually use the variable part of the settings... parts of the preferences work no matter what activity setting selected, others only when RBOP was picked). --//-- [Edit 2 times, last edit by SekeRob* at Oct 19, 2017 6:11:07 PM] |

i found a easy solution:
changing the power plan advanced settings. u can set there minimal cpu usage and max cpu usage puting it down to the point where the notebook dont overheating and dont shuting down. |

 , you did what was proposed 'just set the CPU Ghzs down in OS power management' |

It's a bit more than this. Up until a few days ago, BOINC respected the "use at most X% of CPU time" setting which would prevent overheating (and BOINC being too resource greedy.) A day or two ago, this seems to have stopped working entirely. Even at 50%, my CPU was being max'ed out on my desktop.
This was before I installed the recent BOINC software update. Something is wrong. |
