Hi. This is an odd feature request.
I wish there was a way to adjust CPU time of Boinc manager so that the CPU core temperature would keep a relatively stable temperature. I'm used to program Autohotkey script and I was planning to make something that would work. However there is two problems stopping me from continue:
That is why I form this as a feature request. The idea is that a stable CPU temperature will keep an computer alive longer, because repeatedly temperature changes is a source of motherboard prematurly failure. Bug in the forum: The first item in list is lost, so I have to write same text twice. |

----------------------------------------Install Throttle, configure it to your liking and be done with it. You can also just set the BOINC to use 100% of CPU if you are comfortable with the temperatures at that level (I am :) Also, this would be more suited in the BOINC Forums, since they are responsible for developing the BOINC software, not WCG.  - AMD Ryzen 5 1600AF 6C/12T 3.2 GHz - 85W - AMD Ryzen 5 2500U 4C/8T 2.0 GHz - 28W - AMD Ryzen 7 7730U 8C/16T 3.0 GHz [Edit 1 times, last edit by Falconet at Aug 23, 2015 4:24:53 PM] |

SpeedFan has to be opened as admin as else it is not allowed to read the system temperatures. Still using it to this day when my multi-boot is running in Windows mode, but each time have to answer the UAC question [though it does not bother me much... it's what windows world does to you... stumping the user into submission, which is why it mostly runs in Linux ;]
Feature requests in first order have to be directed at the Berkeley Alpha mail list where the [volunteer] developers and testers write in and report issues. As for TThrottle, it works for many but not for me to satisfaction. Just limits computing unnecessarily too much on hyper-threaded CPU systems... the desired temps not achieved until lowering to 25%. When doing it through the CPU power control panel in e.g. Windows same target temp can be reached by limiting computing to 75% of standard speed, plus, you get a really flat load curve, not the saw-tooth you get with the BOINC in-build throttle and other fixes. Am open to other solutions but that have to be automated. Now things run as fast during cool nights as they do during hot daytime. Oh yes, there's ThreadMasterGUI [In FAQs]. This allows you application level control and gives a smooth load curve [millisecond control]. Application level control is great as the different sciences do load CPU/FPU/APU differently. |

Hi.
----------------------------------------I've an old computer running XP, so I have installed TThrotle 7.30 (latest version that support XP). The problem is - I've no idea how to set ut TThrotle in a way that make Boinc processes reduce cpu load when a given temperature is reached.  [EDIT] I think I got this to work now. I haven't found how to make TThrottle to control only Boinc processes. Anyway - I've set the temperature limit to 90 degrees, and the graph shows that TThrottle tries to keep the temperature there. This is OK method for me - I don't need a very stable temperature, the main objectiv is to prevent this old laptop from overheating. Graph. Before limit was set and after limit was set to 90 degrees: Setup: [IMG]http://i67.tinypic.com/whxuf4.png[/IMG] [Edit 1 times, last edit by Grabbaren at Feb 1, 2016 1:12:59 AM] |

Ref "I haven't found how to make TThrottle to control only Boinc processes."
TThrottle *only* controls the boinc science apps [as descendants of boinc.exe], so you need not tell it anything. Don't know if it leaves NCI (Non-CPU-Intense) apps alone like the WUProp project that use only a fraction of a percent, but guess it does. P.S. Yes your temp graph makes it very clear what the impact is of you controlling the temperature ceiling. |

Update: I've migrated some of my computers from XP to Linux Mint.
Therefore: Is it possible to control runtime of processes under Boinc in Linux too? Does it exist such a tool. |

CPUFreq I use to manually lower the clock-speed and thus temp, another that after tuning, manages the fan speed to make it run even, for nothing so annoying, audio, as the constant revving and slowing. See the 'Confez' thread on Linux in Chat Room for more info.

See the 'Confez' thread on Linux in Chat Room for more info. For some system that's been so developed by the "know how experts", it still lacks the AUTOMATIC control like Win has on Tthrottle!   I do like Linux, but sometimes (OK, often more than not) I think it's still a s...! |

With Linux it is simple to write a few scripts to control the system. Here in Australia in summer temps reached into the high 30s and low 40s Centigrade. I have no air-conditioning so some of my systems started getting hot - really hot. Using some simple scripts managed to get the temperatures under control by varying both the cpu frequency and <cpu_usage_limit> in global_prefs_override.xml - all automatically. The results of these adjustments are monitored and available as graphs...
----------------------------------------http://www.sraellis.tk/frame-28-cputemp.html - changes noticeable towards end Jan http://www.sraellis.tk/frame-28-cpufreq.html - etc see left-hand panel Machine was taken down twice today for a few hours maintenance and tests...

Can you share those XML files? 'cause I'm not that much expert to write my own scripts... |
